Could you track satellites by imaging them from earth? Some are visible to the naked eye at night. It seems like that would be instant and very accurate data.

- sgtnoodle 3y agoI believe that's how satellites are tracked at all? Rather than use visible light, though, tracking stations most certainly use radar, and probably highly directional antennas.
- BenjiWiebe 3y agoI think they are actually measured with lasers, IIRC. Did a lot of research about GNSS when setting up an RTK base station, and used PPP to get the initial location.
