Gravity and Precise Orbit Determination system

GEORB (Gravity and precisE ORBit determination system) GEORB is a software for Precise Orbit Determination (POD) of Low Earth Orbiters (LEOs) and satellite gravity missions, gravity field recovery and orbit design of future space missions. 

GEORB was created by Thomas as a long-term project, initiated in 2007 and released as open source in 2022. It is designed as a versatile tool to support academic research in satellite geodesy and orbital mechanics, as well as industrial applications in Earth observation and space exploration.

GEORB specialises in data analysis of satellite gravity missions and simulation of future space missions, supporting revolutionary missions such as the Gravity Recovery And Climate Experiment (GRACE), and Gravity Field and Steady-State Ocean Circulation (GOCE) missions. The current release delivers data products of precise orbits, calibrated accelerometer data and time-variable gravity field models for the NASA/GFZ’ GRACE Follow-On mission.
