- contingencies 7y agoNotably GNSS-SDR supports not only GPS (US), but also Glonass (Russia), Galileo (EU), and Beidou (China). https://gnss-sdr.org/docs/tutorials/gnss-signals/ https://gnss-sdr.org/docs/tutorials/gnss-signals/ However, I believe it's worth mentioning that if you buy a commercial navigation IC these days, it will support them all out of the box, often with the addition of inertial navigation, which is what allows the navigation system screen to update properly while you drive through tunnels without satellite signals. Other ~viable (for various definitions of "good enough") navigation paradigms include celestial, visual/terrain, other signal sources such as cellular, various radio systems, AIS, etc. Here are relevant chips with prices starting USD$2.7 some of which support GSM/GRPS as well: https://lcsc.com/products/Communication-Modules-GNSS-Modules_940.html?q=gps https://lcsc.com/products/Communication-Modules-GNSS-Modules...
