Radar altimetry data for GEOSAT were acquired by a single ground station that also archived, preprocessed, and distributed the data. The ground station commanded and controlled the satellite and monitored its health and status. Because all GEOSAT data dumped over the ground station had unique ocean-surface coverage with high value, the program required a 24-hour-per-day operational station with a high degree of reliability and maintainability. The satellite command and health-monitoring functions were free from single-point failures, and automation reduced operator error. Store-and-forward techniques minimized altimetry data loss and facilitated recovery from failures. In support of the recently completed geodesy mission, the GEOSAT ground station recovered more than 99.85 percent of the altimetry data collected on board the satellite.
