I wish... I'm on Windows 11 Enterprise with corporate Teams, definitely 100% Microsoft approved combination and:

- on one channel my message never got sent, while on another channel it does work

- sometimes when I scrolled up the old messages doesn't show up, with a 'message removed by organization retention policy' text.. but those are messages from yesterday and sometimes when I restarted Teams it shows up again.. sometime it doesn't but when I opened web Teams it does show up

- sometime I can't connect to Teams for no reason, restarting Teams and computer doesn't help either, went to the IT helpdesk and they spent several minutes redoing what I did until they just googled it and delete the cookies or something

I also used slack and from my perspective its 100% reliable at delivering text messages

Some considerations:

- They don't use GPS frequencies because there is receiver on the moon that receives GPS L1 signals (LuGRE and potentially more in the future)

- Make it easy to acquire for low complexity hardware

- Use 5G forward error correction code to reuse existing hardware implementation

- Design the signal in a way so that the user can easily find start of a data frame

And those are RF level considerations... there will be more considerations needed for the data transmitted over those navigation signal that the receivers need to use to determine navigation satellite position as lunar orbit is much more complicated than Earth orbit

- Building windows GUI apps

Some more questions because the website isn't clear:

- does the FPGA handle digital beamforming in the FPGA fabric? or it controls RF phase shifters for analog beamforming?

- will we have access to FPGA pin constraint file so we can write our own verilog

- can I get IQ samples from the antenna elements and run my own beamforming algorithm / calibration in a separate PC with possible GPU acceleration? or it will be bottlenecked by rpi5 gigabit ethernet?

You do need access to a large telescope (at least 1.2m based on the wiki article), a sensitive detector (is photomultiplier tube sensitive enough??) and most importantly, access to your local laser clearinghouse so you don't accidentally shoot an airplane, blind the pilot and got arrested, or a satellite and start a war (if you believe some guy on quora). Probably the last part is the hardest thing for an amateur

As much as I want to fly with Chinese rocket to encourage launcher competition and redundancy, export controls prevent me from doing that.

It does work at the end, but shortly after we got our first data from space, I decided to quit the space industry and become a test engineer at a terrestrial embedded company instead
