ISRO has launched series of satellites for Earth Imaging for natural resource applications. These applications are being served by various large satellites. Some of the payloads with required swaths & resolutions, which can serve the applications separately in the areas of agriculture, forestry, geology, water resources, land-use, infrastructure build-up, pollution monitoring etc., can be launched on small or micro satellites on stand-alone basis. With the experience of design, development, fabrication and on-orbit operation of earth imaging satellites from IRS-1A to Cartosat-1, the small/micro satellites are planned with advanced technology. The small satellite project is envisaged to provide platform for stand-alone payloads for earth imaging and science missions. The current paper focuses on the first satellite. The satellite is a three axis stabilized bus with two deployed solar panels. The bus carries a miniature dual head star sensor, four micro reaction wheels and micro gyros. The bus can operate in sun-pointing and earth pointing modes and provides good attitude pointing and stability. The details of mission, configuration, and the bus capability details are presented. |
