Must have missed something about why this is not available? Will it be back and if not is there an alternative. Feel this is a real safety benefit.

It is still available via direct link http://glideport.aero/map
I sure hope someone will take it over and continue maintaining and improving it, integrate OGN and ADS-B for a complete integrated tracking. Frankly with all the smart and creative folks we have, I am surprised it is taking so long to find someone to take it over. I will be happy if some of my SSA membership fee will be used to cover it. In fact, this is not just SSA, it is used worldwide, a very valuable tool.

Well, "smart and creative" when it comes to software development, along with an extensive knowledge of the requirements necessary for the soaring environment is pretty much an accurate description of YOU, Ramy. So, what are you waiting for?

I'll put up the price of a couple of six-packs of Sierra Blanca Cherry Wheat, as I seem to recall from a couple of weeks ago that the Cherry Wheat is your personal preference.

Uhh.... OLC shows you have gotten 246 hours of airtime and 22,982 km in 42 flights from six or seven airfields since last October. I'd say you have plenty of free time- you just are too picky about what your priorities are.

Heya;
I was just trying to connect to glideport.aero today and saw this thread.
It's not "down", but if you try to access it via the SSA website, you'll get a broken page.

The problem is with glideport.aero; their SSL Certificate expired on 1 July 2021 (about the same time this thread started!)

The certificate is a "Let's Encrypt!" site SSL. While free, the downside is you have to renew every 3 or 4 months. The good news is that there are all sorts of automated programs that do the renewal for you automatically if you run a "Let's Encrypt!" enabled SSL website.

I sent a note to the "Contact Us" link on the webpage.

Yeah it is still available when accessing directly.
The problem is that no one maintains it anymore. Hopefully someone will take it over. Some suggested I should do it since I have too much time in my hands, but I don’t have the required technical knowledge.

Let me clarify my previous post.
Maintaining an up to date SSL on the webserver that runs glideport.areo is definitely a glideport.aero problem. The only way to get into glideport.aero is to tell the browser, "Hey, don't warn me with all that pesky security certificate stuff. It doesn't matter anyway. I want to log in!" That's definitely a glideport.aero problem.

The SSA's just linking to an ssl enabled page, and the SSL is what's causing the SSA's iframe to have that broken icon logo:

https://members.ssa.org/SailplaneTracker/default.asp?
^^ this doesn't work

https://ssa.glideport.aero/app/gp/map.php?p=Country:US&units=imperial&lang=en&nomenu=1
^^ because this doesn't work

The last link doesn't work because the SSL certificate is expired.

Somebody's gotta have root on that webserver to solve this problem. Who used to maintain it?

It was created and maintained by Pedja Bogdanovich.
I believe the SSA purchased that service from him at the time.
However as of few years ago Pedja is no longer available to maintain it and no one took over as far as I know. Few folks looked into it in the past so don’t know where it is standing. Frank Whitely may know.
The SSLcertificate is only one of the issues, and probably the easiest to resolve.
A bigger issue is with registration and updating profiles on this web site which as far as I know no longer working well so many folks can not register or update their tracker information.
Also there is room for enhancements such as integration with OGN and ADSB.
I don’t have all the technical experience to maintain and enhance this service but am willing to help someone who has the time and technical expertise.

If I just go to glideport.aero it is working fine, although that's via
http, and because it still remembers my login. Why does the SSA site
need to connect to it via https?

Pedja developed the app and supported/improved it when he was excited about its possibilities. SSA signed a users agreement with Pedja years ago. Pedja has never charged us for this service and in fact pays for the server from his own pocket. Once I stepped down as Tracking Committee Chairman I fell out of touch with Pedja.

The maintenance of the site is involved as Google changes their map protocols from time to time and that causes issues. Also there is the customer support from Pedja and SSA volunteers. It is continuous as various user issues arise. Some of the interactions are very frustrating as some users have minimal technical ability while others spend a lot of time talking about ADSb and other improvements that should be made. It does eat up a large amount of time if you desire to help people get acquainted with their equipment and the possibilities. It can be rewarding.

The system was/is very nice and the phone app had/has great potential. However, the limitations of free use and volunteer labor hinder accountability. The SSA is between the proverbial rock of having a free service yet needing the customer support that a paid service would provide. There are other alternatives but none that offer what Pedja has done at the “free” cost of Pedja’s service.

Big thanks to Pedja for what he has done! I hope somebody else picks it
up. Could be a group of people instead of one, to spread the load?

Not sure what you mean the the phone app. Perhaps IGCdroid, which feeds
data in real time into Glideport. It still works, assuming you've
registered with Glideport back when that was possible. It is nice to
have a method for real-time tracking that does not require any extra
hardware: not a satellite communication device, not an OGN tracker nor
OGN ground stations - it only requires a cellphone with data service
(even if it's spotty), and the bandwidth needs are very small. The
developer of the app is hoping to improve it further.

But then, OTOH, maybe the SSA should stop trying to do its own tracking,
and instead join forces with the OGN (glidernet.org)? Why re-invent the
wheel, or rather, shoulder the burden of maintaining a separate system
with similar functionality?

Thanks for clarifying. And many thanks to Pedja for providing this service.
Sounds like there are 2 issues:
1- Lack of SSA tracking committee to handle the support side of things. I am willing to volunteer to help with that.
2- lack of technical person to maintain the service as Pedja did. We need someone with the technical skills and time to do the work.

As for OGN, I have yet to see a tracking tool which come anywhere close in functionality and usability to the SSA tracking capability.

Because it takes its data from the widespread tracking capabilities of satellite based InReach and/or Spot, there is global coverage fed directly into a widely used information bank. As I understand it, OGN tracking primarily comes from dedicated receivers that are privately funded and receive only the weak PowerFlarm signals. I am currently funding one receiver in the Moriarty area and will soon sponsor another when a suitable host with internet and extra bandwidth is found.

SSA is working the issue. There is project access and account access, but that's about it at the moment. Admin control remains elusive and a coaching session is needed. When the new SSA front end launched, some of the links were broken when members.ssa.org was launched. The tasks still upload and existing users can update, but the e-mail responder is not working. As Piet pointed out, the SSL expired, so the embedded SSA Tracker Page won't load. New tracker info for SSA members from the ssa server are not loading and new direct registrations are not working. The final SSA regional for 2021 is in progress. After that we'll see about breaking/fixing it. Pedja has some significant personal issues that occupy his time when not working. He hasn't logged a flight on OLC since he flew the longest recorded flight ever in Colorado at 1272.59km on 9/2/2019. Others looked at or volunteered to take it on, but nothing materialized and somehow their non-involvement did not get communicated. Hoping to get a coaching session on how it's configured so the obvious issued can be fixed. Further development is another topic. Pedja donated his work to the SSA, SSA pays for the hosting, but there are some things that need to be put in order in that regard.

Mark and everyone else,

If the main benefit of glideport is that it displays Inreach and SPOT locations, then glideport as a website is not needed.

I'm doing the exact same thing, parsing Inreach positions, except I'm uploading to the OGN (as if I were a ground station) so that all consumers of OGN data can see it. https://glidertracker.org/, other OGN websites, they can all see your position.

See https://github.com/DavisChappins/InreachToOGN and fill out the google form to add your information to be tracked. I'm running the script on my pi at home. The google form just sends me an email so I can add the info to user.csv (which the script pulls from).

This is essentially the same thing as glideport's user login except I don't need a web UI, a server, an email configuration, a SSL certificate, and all the other overhead that comes with a website. There are already websites out there that display OGN data much better than glideport and don't look like they were made in 1998. If I could get in contact with the glideport guys (contact info is behind a login and I can't create an account) I could pull over all Inreach info and run everyone's Inreach locations on my pi.

What about SPOT? Same data path and I am working on it.
What about ADS-b locations? I'm testing a script that parses an ADS-b API for gliders and transmits their location to the OGN network. When a glider has FLARM and ADS-b, the FLARM signal has priority until it's out of range then the ADS-b position takes over. This would "expand" the range of OGN in the US significantly.

Also Mark, it's cool that you are sponsoring another OGN receiver. I've assembled a few so far and if you need help with an image let me know. I can provide one that you just plug in the SD card with no configuration at all and it will "just work".

Glad to hear someone is working the issue. Tracking is an awesome use of technology. The Albuquerque Soaring Club is trying to install OGN tracking receivers around the flying area to enhance awareness of pilots' locations, both for general information about their status and to upgrade the information given to the NM State Police (who coordinate Search and Rescue operations). Hopefully, SAR won't be needed, but the information is invaluable in an emergency.

The problem with glidertracker web site, as I mentioned earlier, it is a far cry in functionality and usability and doesn’t come close in usefulness for glider tracking. Every time I am trying to use it I find it an exercise in frustration.

1) My post was not about the website glidertracker.org specifically, it was about me replicating the functionality of glideport (spot/inreach tracking) with no server/website overhead and uploading them to the OGN, to be consumed by any website that subscribes to OGN data. Not just glidertracker. It could be https://live.glidernet.org/ or https://glideandseek.com/ or https://www.gliderradar.com/ or maybe a website you want to create based on OGN data.

2) European data laws prevent the retention of data gathered without "consent" so the OGN does not store any data. glidertracker.org goes back 24hrs but that's it. That's all it was designed for. Further back you have the olc and weglide.

3) What part about using it is frustrating? You zoom in and look at what you want to look at. Just like google maps. Just like ADSBExchange.

4) I fear that people have just read and responded to the first sentence and the last sentence while missing the stuff in the middle. I'll repeat it here: I've created and am running a script that gathers Inreach data (Spot soon) and uploads it to the OGN to be visible on any website that gets OGN data. https://github.com/DavisChappins/InreachToOGN if you want to sign up and be visible. In fact, please sign up to help me test the google forms.

I would like that too. But I expect that Alan's app (IGCdroid) only
knows how to talk to Glideport - Alan worked with Pedja on that. If
enough people end up wanting to have it send data to OGN instead (or
additionally), perhaps we can convince Alan to add that feature.

Alan has explained to me that there are two methods of sending data
packets through the interwebs, TCP and UDP IIRC. The first one sets up
a two-way channel and can confirm that the data has gotten through. But
in conditions of poor signals - common when communicating with the
cellphone data system from the air - those connection attempts often
fail. Thus IGCdroid may wait a long time before getting data through,
somewhere, although it then sends all the data accumulated meanwhile.
Alan was considering adding the other type of data sending, which sends
out data packets "in the blind", not knowing whether they were received.
IIRC that's what OGN trackers do. The advantage is that in case the
data is needed for search and rescue, there may be data points from
closer to the accident site. The disadvantage is that the compiled
flight track would be incomplete, since many of the data packets will be
lost. Having the app use both methods simultaneously would achieve both
purposes. But the receiving server needs to be set up to receive both,
and de-duplicate. OGN is only set up for the blind method, which fits
its in-the-moment, no-long-term-memory approach.

Good questions, I will reach out to the developer of IGC Droid and see.
I do know if you send OGN a location packet that is "old" then it displays the time as the time in the packet. It's conceivable that you can feed OGN a list of old packets leading up to the present time and position and it would create that track.

Davis,

There used to be a sailplane locator with a directory of all pilots and their tracker url on the old SSA web site. It does not seem to be available in the old site (which is a bad thing since it was useful to be able to quickly locate the tracking url of a missing pilot) but after pondering around I found it in the old web site:

https://members.ssa.org/MyHome.asp?mbr=6867486834

You may need to logon to access it.
Originally glideport used to sync up automatically with this directory but I believe that over the years it got out of sync and new folks registered directly on glideport.aero so not sure this list is up to date.
I’ll PM you with more information.

"Would it be worth exploring if an established platform such as Flightradar24 could be used to host our aircraft. In addition to ADSB their website indicates potential integration with OGN including FLARM and SPOT. https://www.flightradar24.com/how-it-works."

The people at WeGlide are willing to add satellite tracking if there is enough interest. If enough people contact them requesting it (maybe what Davis has done can speed this up for us/them) it would do more for us feature wise than all the websites listed combined. Take a look at this website in Europe on the weekends..gliders everywhere with tasks laid out. Anyone can easily upload/download a task for a race or badge flight, Skysight integration is coming, LXnav uploads, "Stories", mobile viewing optimized on all platforms etc. Seems to be the way the world is going and BTW, they answer emails and are actively soliciting input. I wouldn't hurt my feelings to see OLC get knocked around a little either...

I also haven't heard much input from Davis question "What functionality does glideport.aero have that the rest of the OGN (glidertracker.org for example) not have?"

A lot!......at least when it was working 100%
1. NATIONAL acceptance of a single platform that works well on all devices and for all users ranging from the casual pilot to sanctioned racing with help from the SSA. Actually many people across the world still use it parallel to OGN (probably for the same reasons I am). It worked really well worldwide (arguably still does) without the infrastructure cost albeit with a small delay (some would say this is a good thing). I'd still like to see a diverse U.S. OGN network, but I don't want to lose satellite tracking either. Thankfully Davis's solution partially combats this, thank you!

2. Stats.....Running stats for OLC optimization. It's great to see people on a map along with their Altitude/Speed/Climb Rate.....but where the hell are they going, or I guess more important where have they been and for how long and at what average speed? Gliders on a map with position IS the most important thing, but the best thing to me about Glideport is that I can also see how they are doing. My version of an aimless Nascar race I suppose......even more fun with a cocktail in hand when I'm not able to go flying myself.

3. The GlideTrack apps disappeared, but at least Alan Walls had everyone's back with IGC Droid for the Android crowd (Now Free by the way.....Thank you Alan!). In fairness, on the OGN's side of the house the SeeYou Navigator phone app (Android and Apple with SeeYou subscription) seems to do a good job of displaying on OGN sites as well, but still has its limitations (not all sites, anonymous CN).

4. Did I mention Stats?......As an aside Niv Levy attacked this OGN Problem from the opposite direction as Davis. A quick and easy registration process and he had your OGN position displayed on Glideport. Works well and displays a second location that's easily discernible from the satellite/phone track already produced. Only problem is the optimization stats aren't accurate (which I'm sure can be fixed, but unfortunately on the Glideport side of the house), and obviously no new users of Glideport can register. At least some ground was gained here and I still think its easier to use than many of the OGN websites. I'm going to leave it running......Thank you Niv!

5. The Glideport site is easy to operate and view right out of the box and works on all platforms......even bouncing in the back seat of a Duo Discus, driving down a rough road looking for a lost boy on landout walkabout, on an airline flight in turbulence, walking the dog, while I push the cart for my wife at the grocery store, at a dinner with boring friends (non-pilots), etc. Frankly it's a good balance of what you need and ease of use. Just my opinion but Glidertracker is a train wreck for viewing.....at least on android anyway.

6. Notifications (not working currently) I could set up a notification when a friend took off so I knew to tune in. Because I often fly alone during the week this was important and my wife has a Glideport account so all she had to do is open the notification email and click the link when I take off.......it takes her to my contest ID in whatever part of the country I am in, she doesn't have to remember a website, know the name of the airport I launched from, and I never once had to give her a tutorial on how to use it......Done! Now we accomplish notifications through IGC Droid......thank you again Alan Walls! I've learned a lot from watching people like Ramy, and the Dust Devil Dash was a blast to watch everyone head straight out.

7. Waypoints can be displayed as well as a task, although I will say I've never been able to figure out how to do the task part of it. Tasks can be displayed in Glidertracker too......also a PITA and not viewer friendly. 

8. Position IS displayed for more than 24hrs. I get it there's only so much server space in the world and OGN is a free service. In OGN's defense they have their own search and rescue protocol that gets around this. I tried reading about it online and quickly came to the conclusion that after a perfectly safe landout outside of cell service I'd probably die of exposure on an ideal sunny 72 degree day before the average club member figured out my location. Once again thank you to Davis as his solution helps to combat this! Its also nice to quickly see who zigged and who zagged either on the time lapse.....even if it is the next day/week/month.

*ADS-B......I wish we all had this instead of Flarm, but that's another argument. Maybe I'm underestimating the draw, but it seems as though of the very few gliders that have ADS-B the users also have Flarm or a satellite tracker. While it would be nice, this seems to be a lower priority.

Thank you to the guys like Davis and Niv who are actively volunteering their expertise to try to come up with solutions. It doesn't look easy but I appreciate it and I'd be glad to buy your next beer.

Thanks Bryce for the excellent summary of glideport capabilities. If we move everything to OGN, I would like to see the same functionality and usability and more, not less.
One problem with new innovations is that unless/until they become the de facto service, they just add more distractions for most users. Ideally I would want to go to one place where I can see all trackers and all flight traces, rather than multiple places. Currently glideport (aka SSA tracker) and OLC are still the de facto, at least in the US.

Ramy Bryce,

Agree with you except with some corrections. There is no "moving to the OGN" because any website can subscribe to the data coming from the OGN.
Currently glideport and its data is like a one way road with a dead end sign. Anything a user enters or any glider data visible on glideport is only visible on glideport and never leaves that site.

The best solution is the simple one and here it is: just have glideport publish satellite tracker locations to the OGN.
That way data is shared and can be consumed on any site that fits the user's needs. When glideport has someone running it please put them in touch with me. In 30 mins we could have my python scripts hosted on their site using their inreach/SPOT user data publishing to the OGN and viewable on any OGN site.

Want to use glideport.aero? Great. inreach/spot locations are viewable.
Want to use glidertracker.org? Great. Glideport is pushing inreach/spot locations to the OGN.
Want to use weglide.org? Great. Glideport is pushing inreach/spot locations to the OGN.

- Should keep in mind that OGN (which stands for OPEN glider network) is
the server which stores the data and offers it to anybody who abides by
the terms of service. There are several options (listed by Davis
earlier) for the front end which one uses to see that data (tracks on a
map). In theory Glideport.aero too could evolve to get the data from
OGN but still do its own display (and task visualization, and searching
and filtering, e.g., show all ongoing flights from a given contest, etc
etc).

Meanwhile the same data would also be visible via all the other ways to
connect to OGN, whether web sites, or apps, etc, independent of
Glideport. That is a major advantage. It also adds resiliency to the
system via redundancy: if Glideport is down at the moment you can still
track a flight via glideandseek or gliderradar or what have you.

The snag is the issue of data retention. OGN policy is to throw away,
or at least lock away (other than for S&R), the data once it is older
than a few hours. If we want Glideport.aero to keep showing past
flights, it can't do that using OGN as the data source. "Can't" in the
sense that the historical data is not accessible on OGN, and also in the
sense that copying the ongoing data from OGN and storing it for the
longer term would violate OGN terms of service.

One solution to that is to abandon the past-flights aspect of Glideport,
and leave that to, e.g., Weglide. The data transfer (from current to
historical) can be set up to happen automatically (with the consent of
individual users).

We now have two things:

1) have glideport publish inreach/spot locations to the OGN to be consumed on other websites. This is easy and should be accomplished when someone is back at the reigns.

2) Pull OGN data to be visible in glideport. Again someone would have to run the site first but this is easy to do. I'm reasonably certain that the reason OGN data is not retained is due to European privacy laws (GPDR and similar). Since glideport is USA and SSA centric, simply don't pull OGN data from Europe. When subscribing to the OGN server you can specify a lat/lon/distance filter so that you only get North American data. Note there are websites that do retain OGN data like https://ktrax.kisstech.ch/contribute.

If we are looking at USA sailplane awareness as a whole, 1) achieves more.

I agree #1 achieves more, or at least has the potential to achieve more and personally I also think this is a step in the proper direction. I'm not married to Glideport (I was just trying to answer the questions regarding features.....sorry it droned on a bit) or WeGlide. What you've accomplished is huge, but I think what Ramy and I are trying to get across is that without someone providing a good user interface to display the data without the features people are already relying on (especially SSA Sanctioned events) the #1 functionality of Glideport (National Acceptance) is tough to replace. Until that interface is developed moving away from the nationally accepted system interweaved in how our governing body operates would be a lateral and temporary adjustment. Then again If the average Joe just wants glider shaped dots on a map he's all set.

The thing I appreciate the most about Davis's approach is that it allows anyone to create that solution and perhaps being tied to one interface isn't a good thing. I only mentioned WeGlide because it seems to be the only website I've found so far that comes close to offering the functionality of Glideport (Id be willing to give up post 24hr viewing) and more important a developer that is willing and actively incorporating input. This seems to be the closest thing to the second half of Davis's solution and as I said before I encourage him to contact them. Perhaps its just a matter of the folks at WeGlide unfiltering the data he's already pushing to OGN? Cant hurt to try and costs nothing, after all they are already pulling the OGN feed.

For those interested below, is an excerpt from WeGlide's response a while back. Take off your tinfoil hats, I didn't give out anyone's contact information, but only directed them to the more prominent users they already had. If you want to add input, I suggest contacting them.

"The points you mention concerning the tracking seem very sensible and I agree that this would be a very nice addition to our live tracking. I have added this to our ToDo list. It will take a bit of time though.
While we are the premier gliding platform in Germany and other parts of Europe already, we struggle to attract gliding pilots from North America. So we would be very interested in
1. Knowing what pilots from the US are looking for and why WeGlide is not very widely used (yet)
2. Getting some contacts to popular pilots and to the Soaring Society of America. We would love to host an online event to have the opportunity to talk about some of the features and get some feedback by the pilots. We have done this for Australia some days ago and it was accepted very positively."

I think 2 is the best solution, until weglide or someone else come up with a better UI for OGN data (including Inreach/spot and even ADSB) ,and become the de facto tracking platform in the US.
