TOPEX/Poseidon battery performance

Abstract

The following observations were made during the first occultation period: (1) C/D ratios tend to be higher during the initial and final segment of the occultation period; (2) the net overcharge parameter is useful in assessing C/D's; (3) small peak power cusps were present during the initial and final segment of the occultation period--no cusps during the remaining period; (4) small differential voltages (less than 12 mV) were recorded; and (5) the peak charge current was within the recommended limits. In summary, the batteries are operating within recommended limits, and their performance is excellent.
