Brad Parkinson, the father of GPS and PNTAB, they've been trying to lobby the US government to remove ITAR from that technology so the civilian can benefit from anti jamming, and finally they managed to do it sometime last year. Now it falls under EAR

- This study is the source of LinkedIn ads from climate change where they try to convince people to move from gas to electric because of bad health effects

- But it doesn't invalidate the study, because of course burning something indoors creates some sort of emission, which may causes asthma in kids

- But its not relevant for me because I'm a single adult not a child and I don't cook that much anyway

- And even when I used to have a gas stove, I used my induction burner more often as its more powerful and makes less waste heat compared to my gas stove

- and the reason I bought an induction wok burner from aliexpress, it can go much hotter than my gas stove

- But one thing that gas stoves excel is even the cheapest gas stoves have a smooth analog control, making it possible to gently heat things, which is important for cooking omelette. For the induction burners I have, it uses on off control, which will scorch the food if your setup (food + cookware) have low thermal mass to smooth it out. You think with the advancement of power electronics because of EV, ebikes, drones and AI data center power supplies someone is able to make a cheap induction burner with analog power control

That plain text looks like what a software GNSS receiver outputs as its very verbose, and this paper: https://radionavlab.ae.utexas.edu/wp-content/uploads/2022/10... , a paper about a software receiver mentioned this:

> PpRx has been licensed through the Radionavigation Lab to multiple commercial companies, but notably a major aerospace company that uses the technology across their suite of advanced spacecraft and satellites. The SDR is deployed across the company’s mega-constellation of satellites used for broadband Internet

Yeah no, your language will be DOA if you don't have bit twiddling, because you can't write arbitrary binary file parser / writer without some sort of bit manipulation.

Even matlab have bit twiddling function

Another example is high frame rate thermal camera, US companies are banned from exporting cameras above 9 fps, while chinese companies freely sells 50 fps cameras

1. Public ephemeris from space-track (celestrak) is notoriously inaccurate after a while. Less of a problem for starlink as they give free access to high accuracy ephemeris from their onboard GPS receiver: https://starlink.com/satellite-operators

2. For proprietary signals like starlink they can change signals whenever they want without telling you and break your positioning algorithm. For example, starlink used to transmit some sort of narrowband CW wave at their frequency band, which can be received by cheap ($20 ish) RTL-SDR dongle and satellite TV antenna: https://www.rtl-sdr.com/receiving-starlink-signals-with-an-r... . Everyone speculates that its a beacon signal, research papers were written trying to exploit doppler positioning from those signals. Then the signal disappears, as its possible that they don't intentionally transmit those signal. They you can't use cheap hardware to capture the signal, you need expensive hardware that can capture the full 250 MHz bandwidth. This is not a problem if you use standardized signals where they can even intentionally add positioning signals like 5G or digital TV

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
