Abstract

This paper describes the first in-space demonstration of a “Green” propulsion system on the PRISMA main satellite. The PRISMA mission is a unique opportunity to demonstrate the High Performance Green Propulsion (HPGP) system in space, and thus take a significant step to towards its use in future space applications. The PRISMA mission objective is to perform autonomous rendezvous and formation flying (Main and Target Satellite) including homing and proximity operations. The PRISMA satellites were launched on Dnepr from Yazny in June 2010, Figure 1. The HPGP system is used both for providing the required delta-v for the PRISMA main satellite manoeuvres and as an experiment with the objective to demonstrate performance in space. Delta-v is nominally generated in an autonomous and combined operation of the HPGP and Hydrazine propulsion systems while the performance measurements are performed with one propulsion system at the time. PRISMA is an international technology demonstration program with Swedish Space Corporation as the Prime Contractor and major contributions from DLR, CNES and the Technical University of Copenhagen.
