laika VS rtkbase

Cool, so it looks like they take the “raw” GPS location (after the GPS module does processing to spit out a lat/long) and applies statistical methods with a model of the actual 3D geometry. Seems like a smart way to improve the accuracy from “userspace”.

This reminds me of the Comma.ai project, Laika [0]. Since they have access to the raw GPS module data (Ie the actual timings of each received satellite transmitting), they can do things such as correcting for troposphere/ionosphere delays by looking up the relevant astro data as recorded by NASA and others.

Thank you for the information, fascinating. I've been curious about this for a while, how drone swarms are coordinated by software to perform intricate shows. There must be some interesting questions to solve, like how to avoid collision, or if they need error correction in case of wind, etc.

I learned RTK means "Real-time kinematic positioning". https://en.wikipedia.org/wiki/Real-time_kinematic_positionin...

Apparently it's possible to set up one's own RTK station. https://github.com/Stefal/rtkbase https://learn.sparkfun.com/tutorials/setting-up-a-rover-base...
