Playing with Meshcore. My companion doesn't have GPS built in but of course my phone does. Updating my location info requires a bunch of clicks through Meshcore so Claude and I just wrote an Android App that discovers my companion using Bluetooth and with one button updates the location on my companion. Still testing but it looks good so far. It took about an hour including breakfast!

DARPA wants to replace GPS dependence with new class of sensors

Every GPS signal on the battlefield is a vulnerability waiting to be exploited, and Russia, China, and Iran have all demonstrated the willingness to exploit it. DARPA just announced it is going to solve that problem from the inside out, by building a navigation sensor so precise that it no longer needs GPS to know

How The Heck Does #GPS Work?
Answer is in some ways simple, and in other ways more complex. GPS is fundamentally a translation tool: it converts time into distance. A #satellite sends a signal, your phone catches it, and the delay between those two events tells the phone exactly how far away the satellite is. Everything else is about making that measurement precise enough to be useful: accounting for bad clocks, satellite geometry, and eventually, #Einstein’s theories.

Creating a carrier-to-noise heatmap from my #GPS data. Just because I can. Now wondering why those QZSS satellites (194-197) seem to be taking turns in sending.
