BILSAT-1(1) is a 129 kg enhanced microsatellite developed by SSTL with TUBITAK-BILTEN engineers as part of a technology transfer programme. The main objective of the mission is remote sensing. The multispectral imager of the satellite has a 26-metre ground sampling distance at 686 km altitude giving a swath width of 55 km and the panchromatic imager of the satellite with 12-metre ground sampling distance gives a 25 km swath width. The satellite has off-axis pointing capability, provided by the ADCS systems, which (amongst other benefits) reduces the revisit time for any given point on the Earth. The advanced and capable Attitude Determination and Control System including star cameras, sun sensors and rate gyros provide accurate and precise attitude information allowing a very high degree of attitude knowledge. Tetrahedral mounted four reaction wheels on board will make the satellite extremely agile, allowing fast slew maneuvers about its roll and pitch axes.
