Abstract :
RA-2 has been designed and is under development by Alenia Spazio as instrument prime contractor for the European Space Agency (ESA). The main mission requirement for RA-2 is constituted by global coverage over all surface types. Its operation is no more restricted to the open ocean and ice covered regions as per ERS-1 and ERS-2, and other previous altimeters. This implied a radical different design approach, mainly in the areas of: acquisition, on board tracking algorithm, operation concept
