C-nav 5000

[Glendora Starr]

The C-Nav5000 offers integrated GNSS capabilities that allow tracking of multiple systems. It features triple L-band channels for correction tracking and is software-configurable to user requirements.

The C-Nav LEO Correction Service exclusively uses the Iridium satellite communications network to deliver GNSS (GPS, GLONASS and Galileo) augmentation data to the C-NavX1 GNSS Receiver. Utilizing the Iridium LEO satellite communications network we can offer a true global service from pole to pole.

C-Nav correction service is the oldest precise point positioning corrections service, offering corrections for the C-Nav3050 and C-Nav5000. The C-Nav5000 offers an improved accuracy level over legacy products implementing an improved positioning solution.

The C-NavX1 is a quad-band GNSS receiver built to deliver precise positioning for the most challenging of marine operations. Supports decimeter-level multi-constellation positioning utilizing the latest C-Nav LEO correction service delivering precise positioning from pole to pole through the Iridium LEO satellite communications network.

For high-integrity systems with dual GNSS receivers, the interface will "OR" the two TTL sources for output to peripherals that require a continuous 1PPS for time stamping. This output is maintained should either GNSS input fail.

The SAAB R6 is a type approved IMO-compliant navigation system featuring sensor and 7" CDU(Control and Display Unit).
The R6 NAV includes a Bridge Alarm Management system, dual LAN interface, 1PPS output, 8 output and 5 input ports, IALA and RTCMv2 input, Multi constellation GLONASS, GALILEO and BeiDou GNSS.

The C-Nav289 is a GNSS antenna that tracks all GNSS constellations, C-Nav corrections, and SBAS satellites. It has special out of band rejection filters for INMARSAT and IRIDIUM. It is housed in an all-polymer enclosure for marine application. The antenna is listed in the NOAA GNSS Antenna Calibration tables as C-Nav289.

The C-Nav Combiner enables the use of separate GNSS and L-band antennas. It is used in high-latitude operations where the low look angle of the separate L-band antenna enables reception of correction signals that is not possible with a standard integrated GNSS/L-band unit.

C-NaviGatorIV is the next generation of Control Display Unit providing real-time system accuracy and performance indicators for multiple GNSS receivers; with options for various NMEA inputs and outputs. Improvements over the previous generation include a larger higher resolution display, multiple Display port output for remote display expansion, AC/DC power options, double the USB ports and a move to Microsoft Windows platform. It is fully compliant with the latest guidelines for GNSS positioning within the oil and gas industry, as per IMCA standards.

The C-Monitor application provides a graphical interface for supervising the operation and performance of one or more differential GNSS systems. It is compliant with the latest QA/QC guidelines for GNSS positioning within the oil and gas industry per the International Association of Oil & Gas Producers (IOGP) and the International Marine Contractors Association (IMCA).

C-Scape position monitoring and situational awareness software provides independent real-time monitoring of any dynamic positioning (DP) system. The simple, intuitive interface furnishes situational awareness to users during drillship, dive boat, remotely operated vehicle (ROV) vessel, and other operations by blending multiple sensors with map file overlays.

C-Tides is a worldwide tidal data software package that combines the exceptional vertical accuracy of the C-Nav3050 receiver with advanced ocean surface models to deliver real-time elevations relative to the mean sea surface (MSS) and EGM2008.

Correction signal tracking has been increased to three channels to ensure continuous precise point positioning (PPP) data, improving satellite tracking, accuracy and safety. Following the philosophy of the C-Nav3050, the C-Nav5000 hardware is designed to offer optimisation and longevity supported by a multi-year plan for software feature additions. Additional improvements on the existing C-Nav3050 include an upgraded I/O system featuring an increased number of serial ports and Ethernet connections. The C-Nav5000 will have the same world-class support structure as the rest of the C-Nav product portfolio and will be available this summer.

Why is Control Center on Monterey listening to port 5000 and port 7000? I have used these ports for years for local development, but now find them in use by Control Center. Is this worth filling a Feedback about?

The Remote Audio Output Protocol, AKA AirTunes, AKA AirPlay, has been using port 5000 since the year 2004. This is nothing new. All AirPlay receivers including AirPort Express and Apple TV use port 5000. If you've ever used Airfoil on your Mac (Airfoil Speakers was released in 2008), that also uses 5000 for the same reason. AirPlay receiving is new to macOS Monterey, but AirPlay itself is very old, predating Flask and these other web development environments. No, Apple is not trying to make web development difficult.

It seems that port number 5000 was never officially registered with IANA, and has many more conflicts.Can we kindly ask Apple to register their service ports and use IANA assigned ports in the future? _of_TCP_and_UDP_port_numbers

Unfortunately port 7000 was used to hack my iMac Apple Silicon 2 days ago, to control over my app, updated Xcode from unknown source and also changed Viber messenger. The hack thing was almost invisible, performed via previously hacked wifi router. So I decided to restore my system. I performed power button holding to enter my system options. I erased whole ssd and tried to load fresh new system. Well it does not go well, as the update server was unreachable - strange seemed to me. Than I realized that hackers have done something to my system options to force me not to revive or restore whole MacOS. I had to perform terminal destroy disk keys operation, ( terminal> xartutil --erase-all ) than I have found my iMac like diskless/bricked. I used Apple Configurator 2 to get my system back online and here I'm restored and healthy. Port 7000 is definitively dangerous to listen on while bad guys nearby... I almost forgot - my MacOS firewall was set to "blocking all incoming connections". So it seems there is still a way how to enter my MacOS.

This answered two of my questions on port usage, A, but and B, why my Control Center had been receiving incoming connections. However, I like Digitec have tried resetting my mac due to a previously hacked router issue, and just end up setting up another OS in a different partition somehow, and I am not new to this by any means. Files I can't access and the directory is a mess. So, Digitec, what can I do to avoid bricking and having to use the Apple Configurator 2 to revive? Any options there to make this a little easier and less time-consuming?

Back to the Port Issue, I don't understand why this Airplay Feature would use an insecure port AND have control center access on as a privacy setting by default. I've never seen this in my Preferences pane, which made me think that hackers could also access my accessibility settings which have never been set up in this version of OS on my Macbook, but I see now that there are enough options pre-set for a hacker to control my computer right there from the control center, and it's allowing incoming connections by default. Is this a design flaw we think?

On the right you'll see TCP *:5000 (LISTEN) usually listed once for each IP version, and on the left is the name of the program that's sucking on the port, which is ControlCe if its AirPlay. If nothing is using that port, then it won't be listed.

Funny thing just happened: I turned off AirPlay Receiver, started my service on port 5000, turned AirPlay Receiver back on, it is now happily listening on port 54842 in addition to port 7000 on which it was also listening before.

I've also captured traffic that is malformed coming into my brand new Mac Apple Silicon. Port 7000 was open and bound to ControlCenter. The traffic I've captured (PCAP) respembles the airplay protocol RTSP. using a blist00 tag followed by a payload.
Interestingly, the attack traffic (dport 7000) has TCP options set. They are 12 bytes. 0101 and then 10 more bytes for an array of two timestamps. I'm pretty sure this is part of the attack payload.

Plus one above. This is seriously stupid Apple on so many levels - firstly using a known developer port is dumber than a rock. Secondly constantly changing the setting locations under cryptic naming conventions is idiotic as well. Do your Product managers really have such a skewed sense of intuitive organizational structure? Here is an idea -> try alpha sorting by service and functional category (General has no meaning at all lose it). See: is an example

User PreferencesAccessibilityAppearanceControl Center (have the ability to alpha sort anything and everything and frankly create and or rename categories)FocusLogin PasswordPrivacy and SecurityScreentimeSiri & Spotlightetc.

I think you get the idea. This would be a meta organizational standard with a location design pattern, not some random organization stragegy that "seems" to make sense when in reality it does not, and also does not scale at all. the layout changes from OS iteration to OS iteration and makes solution finding nearly impossible as many search results are returned, one for each new change, that do not apply (as happened here). The fact that this is not more obvious a problem is unbelieveable and the same patteren repeats over and over with the Apple development model. C'mon folks do more research on optimal organizational construct logic, patterning, searchability, optimization, and scaling over time. And don't use known development ports for propietary service your users may or may not chose to use.
