Gravity and Precise Orbit Determination system
GEORB (Gravity and precisE ORBit determination system) 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 is currently being utilised and further developed at DORUS Space Lab. It has also been deployed at Aristotle University of Thessaloniki (GR) and Aalborg University Copenhagen (DK) and has supported projects of the European Space Agency (ESA) and Geoscience Australia.
GEORB specialises in data analysis of satellite gravity missions and simulation of future space gravity 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.

Data Products
Data products are being computed within in-depth orbit analysis along with space-borne observation data processing. GEORB delivers data products of precise orbits, orbit simulation data, in-orbit calibrated accelerometer data and time-series of gravity field models.
Data, as aforementioned, are available upon request or agreement. Details are available at georb.gr/data-products/
