CRYOSAT ISVV

Customer/Partner
ESA (ESTEC), Astrium Gmbh, Softwcare Ltd

Description
Cryosat is a three-year radar altimetry mission, scheduled for launch in 8th October 2005, to determine variations in the thickness of the Earth’s continental ice sheets and marine ice cover. Its primary objective is to test the prediction of thinning arctic ice due to global warming.

The Cryosat Independent Software Verification and Validation (ISVV) project started May 2002. CSW is leading this program for the CryoSat satellite prime – Astrium Gmbh.

The project features both verification and validation activities targeted at the spacecraft Central Data Management Unit (CMDU), including both the Attitude and Orbit Control System (AOCS) software and the Onboard Data Handling (OBDH), as well as a set of several instruments, including a Star Tracker and SIRAL, and the Solid State Mass Memory (MMFU).

Still at an infancy stage, the ISVV scheme, as presented in ECSS standards, was significantly tailored by CSW for this project. The consortium is responsible for the definition and execution of the test plans at the customer premises.
