Flight Results from the PRISMA GPS-Based Navigation

Kurzfassung

The paper presents the flight results coming from the GPS-based navigation system of the PRISMA satellites and collected during the first four months of the mission. Overall the mission demonstrates the successful design and implementation of an innovative spaceborne autonomous navigation system based on low-cost GPS receivers for accurate real-time absolute and relative navigation. The onboard navigation system is complemented on ground with an advanced facility for precise orbit determination which serves as verification layer during the operations.
