ELISA [CNES]
ELISA [CNES] |
ELISA (ELectronic Intelligence by SAtellite) is a demonstration project sponsored by the French defence procurements agency (DGA). It will prepare the ground for the future operational programme ROEM (Elint) for mapping the positions of radar and other transmitters throughout the world and determining their technical characteristics.
The programme will attempt to meet two needs:
ELISA involves Elint payloads which will be carried on board four Myriade micro-satellites. These will be placed in Low Earth Orbit a few kilometers from each other and will record all signals intercepted. When the measurements stored by each micro-satellite are combined, it will be possible to locate and characterise the source of each signal.
The ground segment is made up of two connected units, one for controlling the satellites and transmitting operating schedules, the other for preparing the schedules and processing the measurements.
CNES is providing the SSC and is also chief contracting authority for the project
together with the DGA. The industrial prime contractor is a consortium of EADS-Astrium SAS
and Thales Systčmes Aéroportés SA as joint contractors, with EADS as the mandated
representative.
