Design of Safety Procedures for a Multi-Satellite Formation Using a Continuous Control Scheme

Kurzfassung

The concept of multiple satellites in formation represents a significant advancement in enhancing the capabilities of synthetic aperture radar interferometry. Maintaining the correct baseline and a safe configuration among the vehicles is vital for high-resolution across-track SAR interferometry missions. This study focuses on across-track single-pass interferometry, based on fixed time-invariant baselines, and introduces a novel guidance and control strategy specifically designed to address safety procedures in case of off-nominal onboard conditions. The research examines the capability for rapid formation reconfiguration to enter safe mode in terms of minimum propellant consumption and passive safety.
