A Python package that takes in GPS observations of formation flying satellites
LEOGPS
LEOGPS is an open-source Python package that takes in GPS observations of formation flying satellites in pairs, to perform single point positioning (SPP) and precise relative positioning via carrier phase double-differential GPS (CDGPS). It currently supports only observations from the GPS constellation (L1/L2 frequency), with observation files in RINEX v2.XX format.
LEOGPS gives credit to the University of Bern, for their kind sharing of CODE precise GPS ephemeris and clock files.
Note that for formation flying applications, the purely kinematic CDGPS approach in LEOGPS is usually accurate up to 1m for baselines less than 200km.
Installation and First Steps
First, clone this repository. That’s the only step in installing it. The user can then run the application by running ‘leogps.py’, in the main directory, and you should
