23 September 1993 Infrared earth sensor for detection of solar sail deployment of INSAT-2A
Author Affiliations +
INSAT-2 series satellites are second generation, multipurpose satellites developed by Indian Space Research Organisation for telecommunication and meteorological remote sensing. INSAT-2A was launched successfully in July 1992. The solar sail mounted on the north face of the satellite balances the differential solar radiations torque on the solar panel mounted on the south face. The sail, being lightweight, during its deployment causes very little attitude disturbance on the satellite to sense the deployment. A novel utilization of an earth sensor (ES) mounted on the same face of the satellite gave a clear indication of the deployment initiation and the progress of the boom extension during this period. This paper briefly describes the observations made using the earth sensor during the sail deployment and analyzes the data received in terms of the sail extension in this period.
