ooooo Yea forgot about RTK GPS. I’ve always found them to be so brittle but that’s because I’m in a city.
In the wide open sky, I’m guessing it’s pretty reliable.
Vision systems would be pretty useless with the low visibility of the smoke and fire. So I thought maybe it was some kind of radar configuration.
Anyways, I’d pay a lot of money to pick the brain of the GNC team here.
- psb217 2y agoWhy bother with GPS or other "absolute" coordinate systems? Once the rocket's in close, all that matters is relative position and orientation of the rocket with respect to the landing apparatus. Eg, if you had many sensors in known locations on the rocket and many sensors in known locations on the landing apparatus, and you could measure relative positions between all pairs of these sensors, you could get extremely precise relative position/orientation information without beaming information to satellites or whatever.
