The low Earth orbit (LEO) operations of the RADARSAT spacecraft require high performance batteries to provide energy to the payload and platform during eclipse periods. Nickel-hydrogen cells are currently competing with the more traditional nickel-cadmium cells for high performance spacecraft applications at GEO (geostationary Earth orbit) and LEO. Nickel-hydrogen cells appear better suited for high power applications where high currents and high depths of discharge (DOD) are required. Although a number of GEO missions have flown with nickel-hydrogen batteries it is not readily apparent that the LEO version of the nickel-hydrogen cell is able to withstand the extended cycle lifetime (5 years) of the RADARSAT mission. The problems associated with nickel-hydrogen cells are discussed in the context of the RADARSAT mission and a test program designed to characterize cell performance is presented.
