PRISMA

• Schweden constructs both satellites (Mango and Tango), provides the ground segment and participates with the following experiments
• High Performance Green Propellant drive system (HPGP)
• Newly developed micropropulsion drive system
• Newly developed mass spectrometer
• Some other tests
• Techno Systems, Italy, provides an innovative and versatile digital video system
• DLR is responsible for the GPS navigation system, demonstration of autonomous formation flying experiments and for the flight operations during the second mission phase
• CNES, France in co-operation with CDTI, Italy, provides a RF sensor (FFRF) for the autonomous formation flight und operates some more experiments
• Technical University of Denmark, provides a visual sensor (VBS) for the autonomous orbit keeping and distance measurement

The project started 2005 with the design of both satellites and the concept of the experimental phase. On June 15, 2010 PRISMA was launched from the Russian launch site Yasny using a Dnepr rocket. The first part of the satellite qualification and testing could be successfully done by the Swedisch flight operations team of SSC in Solna near Stockholm. This team also carried out flight operations during the first half of the mission. GSOC took over responsibility for the mission control during the second mission phase. The handover to GSOC was in March 2011 - the return to SSC on August 22, 2011.
