The Mission

Prisma is a technology mission primarily aiming at the demonstration of different sensor technologies and guidance navigation strategies for rendezvous and formation flying in space.

The project consists of two spacecraft, one advanced and highly maneuverable called Mango, and one called Tango. Mango is equipped with several sensor systems for formation flying and rendezvous purposes such as GPS, a vision based camera (VBS) and a radio frequency based navigation instrument (FFRF) together with advanced guidance, navigation and control algorithms. Several high level demonstrations have been performed successfully.

OHB Sweden contribution

OHB Sweden acted as Prime contractor for the Prisma mission and designed, developed, manufactured, integrated and tested both spacecraft, Mango and Tango.
We also operate the spacecraft in orbit since the launch in 2010.


The Prisma mission was financed by the Swedish National Space Board (SNSB).

The major partners in the PRISMA project were:

    • German Aerospace Centre (DLR)
    • French Space Agency (CNES) in cooperation with Centre for the Development of Industrial Technology (CDTI), Spain
    • Danish Technical University (DTU).

Launch date

The satellites were launched from Yasny in Russia on 15 June 2010 to a sun-synchronous orbit at 700 km altitude by a Russian Dnepr rocket.
