Paper Abstract

CNES (French spatial agency) will provide the AltiKa high-resolution altimeter, Doris instrument and the LRA (Laser Retro-reflector Array) for SARAL (Satellite with ARgos and Altika) in cooperation with ISRO. The paper presents the LRA, its design and its key performances. The nine corner cube reflectors have been manufactured with very stringent dihedral angle offset precision. The tests done will be described. Specific modelisation and analysis (thermal gradient), specific test (thermo-optical test) and optimizations will be described.
