Innovation: Orbit determination of LEO satellites with real-time corrections Posted on 24 Apr 2017 in the Featured Stories & From the Magazine & Innovation categories.

Precision on Board
Described are the results of realistic simulations carried out to precisely position a low-Earth-orbit satellite using a source of real-time GPS corrections actually transmitted by a network of geostationary satellites. Even accounting for data outages, 3D positioning accuracies better than a decimeter have been obtained. Precision on board? Not right now but likely coming real soon. Read more»
