Abstract

Gravity and precisE ORBit determination system (GEORB) is a software for precise orbit determination of low Earth orbiters, gravity field recovery based on satellite gravity missions and orbit design of future space missions. GEORB has been applied in orbit determination of the Gravity Recovery And Climate Experiment (GRACE), GRACE Follow-On (GRACE-FO) and Gravity Field and Steady-State Ocean Circulation (GOCE) missions. GEORB has been recently released as open source on GitHub (https://github.com/Thomas-Loudis/georb). The current release provides features focusing on orbit determination of the GRACE missions including the calibration of the on-board accelerometers and the analysis of intersatellite ranging observations.
