Clyde Space delivered two flight model Battery Charge Regulator (BCR) System to The Scientific and Technological Research Council of Turkey (TÜBİTAK). The Battery Charge Regulator is specifically designed for use with Lithium Ion battery technology. Features of the system include: four 85W Solar Panel Maximum Power Point Trackers; redundant battery over-charge protection; digital interface to battery, and solar panel telemetry. The Clyde Space system was ideal for the 120-kg RASAT mission, which uses a 9Ah Lithium Ion battery for energy storage. RASAT is the first earth observation satellite to be built and developed in Turkey. The 120-kg spacecraft is due to be launched into a 700-km sun-synchronous orbit in late 2009. RASAT is 3-axis controlled, has an optical imaging system with 7.5-m resolution panchromatic, and 15-m resolution multi-spectral imaging capability. The satellite will carry a new generation flight computer (BİLGE), X-band transmitter module and a real-time image processing module (GEZGİN-2). Its high-resolution imaging capability will be used in mapping, disaster monitoring/mitigation, city planning, environmental studies, landcover mapping, classification, and forest fire monitoring.
