Metop introduction OLD VERSION
The MetOp Satellite is part of a European polar orbit satellite system which will fulfil a combined operational meteorological and climate monitoring mission.
MetOp is comprised of two major modules:
- The Service Module (SVM) the design of which is largely derived from SPOT 5/Envisat programmes, (ENVIronment SATellite) which provides the main satellite support functions, such as command and control, communications with the ground, power, attitude and orbit control, and propulsion. It also interfaces with the launcher.
- The Payload Module (PLM), derived from ENVISAT, on which the MetOp instruments and associated payload support equipment (data management and communications, electrical distribution) are accommodated.
This split provides the basis for a convenient physical and functional separation between the SVM subsystems and the instrument dedicated equipment. In addition, the interface decoupling at module level facilitates parallel development and integration of service and payload modules, and allows for a schedule-efficient satellite integration programme where only the minimum of system level activities is needed for final verification.
A structural model programme has been performed with both modules coupled and representative instrument models or mass dummies also included.
