Hi everybody, I’m trying to understand how Orekit could be used to estimate the (x,y,z) coordinates of a GPS satellites at a given instant using a YUMA file.
My knowledge is very limited at the moment, I’d like to explain what I have understood so far. Using
YUMAParser I can generate a
GPSAlmanac for the target satellite. Knowing the orbital parameters and when the almanac was generated I should create an
Orbit instance (maybe creating a
KeplerianOrbit instance) providing the right
Frame instance. Using a
Propagator, I can then estimate the
SpacecraftState at the target instant and lastly get the coordinates I’m looking for.
Am I on the right path? Thank you very much!!
