The Prisma mission was funded by the Swedish National Space Board (SNSB) in partnership with CNES, the DLR (Germany), and the DTU (Denmark).

The Swedish Space Corporation (SSC) was the prime contractor, in charge of design, and space and ground segments integration and operations. The SSC also implemented the in-orbit experiments involving Autonomous Formation Flying, Autonomous Guidance and Rendezvous, as well as Tri-dimensional Proximity Operations including Final Approach and Separation. All flight operations were controlled by the SSC using its ground station in Kiruna.

PRISMA/FFIORD Organization


Development of the FFRF subsystem was co-funded by CNES and the Spanish Centre for Industrial Technology Development (CDTI). The CNES/CDTI partnership was regulated by a bilateral cooperation agreement.

Within this partnership, CNES acted as the primary technical authority and funded RF subsystem components made by Thales Alenia Space France (TAS-F), whereas the CDTI funded both Spanish subcontractors, Thales Alenia Space Spain (TAS-E) and GMV. TAS-F provided the technical specifications and timetable for Spanish developments, even though the CDTI had signed a direct contract for these.

The CDTI remained proprietor of any element it funded.

A specific agreement was set up to create a framework for the exchange of raw instrument and satellite data between the SSC, the DLR, and CNES, within the Prisma mission.

CNES used raw GPS data provided by the SSC and the DLR to validate the FFRF subsystem by comparing relative orbit data from both instruments.
