T711-803sd Robust Atmosphere Error Modelling for Sustainable Operations (expro+)

Objectives: The objective of this tender is to develop robust atmosphere error modeling for sustainable space operations, which supports spacecraft operators in understanding and mitigating orbit uncertainties induced by atmospheric inaccuracies and solar/geomagnetic conditions. This involves creating new products and services to aid New Space operators in orbit planning tasks, such as collision avoidance and long-term disposal strategies, especially for small satellites and low LEO (below 600 km) applications. The project emphasizes the derivation of real-time calibration parameters using historical and current data, which will be integrated into the GODOT flight dynamics software, enhancing both short- and long-term orbital predictions.
