resurrecting a hab project

[Phil Newman]

Hi all.

Over the last couple years i've been on/off building a hab, primarily following the guides on ukhas. I've been doing it by myself so sometimes my motivation has waned.

I wanted to build as much as possible from scratch, so I built my own circuit boards and RTTY tracker using a rpi pico and ntx2b. I pretty much had everything complete last year but stalled when it came to buying the chute, balloon, and the rising prices of helium.

And now that habhub has gone i find myself wondering how best to move forward.

I'd like to keep my tracker if i can. I understand that the basic lat, long, alt, fields are supported by horus gui + sondehub amateur. Or that HAB Base can also support the additional fields of the ukhas sentence (temp etc) which would be nice to keep. So I think i'm ok to stick with my tracker? Is that right? or should i really consider switching to LORA or horus binary? 

Another issue I was facing is that I live very close to Gatwick Airport. I'm pretty sure that rules out launching anywhere nearby. When looking further afield for a launch site, do you have to have the landowners permission or could I use a public park as an example? 

Thanks for any assistance you could provide.

Phil.

SR: Yep - helium is very expensive - you could consider Hydrogen - or cut Helium requirements to a minimum - reduce you payload weight and ride on a smaller balloon.

SR: If you already have RTTY working the Horus GUI support of basic UKHAS RTTY is the way to go IMO (loosing the extra fields).   There is HABbase - but that only works on windows I believe.  An alternative is to build your own decoder to parse your messages and upload to SondeHub.  It could run on the same machine as FL-digi read the telemetry port and upload to Sondehub.

SR: personally I'd always get the landowners permission - if its public land check the by-laws (release of balloons is sometimes covered). I certainly would not use Hydrogen where Joe public can turn up smoking a cigarette.  The CAA permit request now asks if you have got landowner permission - although I'm not sure what happens if you say no.

Thanks for any assistance you could provide.

During the flight of "X1" last month, I was using FL-DIGI linked to Dave's HAB Base, which was indeed automatically uploading to Sondehub (as G6GVI-B).

However I was simultaneously receiving LoRa (mode 0) from the same antenna and got many more packets from that (compare G6GVI-L on the Grafana chart below) - perhaps because I didn't need to keep manually adjusting the frequency, as I did to track the RTTY signal.

Re HAB Base only being on Windows, if there's enough interest then I'll do a Mac version.  Let me know if interested.
