Paper Abstract

A combined absolute/relative navigation experiment, currently under analysis in Italy, is described. Two space vehicles are constrained to take measurements from the same GPS satellites. The absolute and relative state vectors are determined by a Kalman filter that processes the differences between the two vehicle measurements relevant to the same GPS satellite and the absolute measurements of each vehicle. The experiment is implemented using two small coorbiting satellites, Pegasus/Scout II compatibles, flying in circular orbits at an altitude of about 400 km and manuevering to vary the distance between the two satellites. Absolute and relative position and velocity are autonomously computed onboard the vehicles with accuracies sufficiently high to allow GPS-based rendezvous operations and autonomous navigation.
