SRMSAT is a Nanosatellite built by students at Sri Ramaswamy Memorial University(SRM University,Chennai) in India. It was launched from the Indian Space Research Organization's Satish Dhawan Space Centre at Sriharikota in October 2011. atop a PSLV-C18 rocket. The satellite is an Indian technology demonstration and Earth observation satellite which will be operated by the SRM Institute of Science and Technology. This nanosatellite will be used to monitor Greenhouse gases in atmosphere. It is a 10.4-kilogram (23 lb) spacecraft, which measures 28 centimetres (11 in) in length by 28 centimetres (11 in) in height and width. Its development programme cost around 1.5 crore rupee. It has a design life of one year. The launch was a multi-payload mission shared with Megha-Tropiques, VesselSat-1 and Jugnu.
SRMSAT is controlled by a 28.8 MHz Atmel microcontroller. Communication is via UHF, with a downlink at 437.5 MHz providing a data rate of 2.4 kbit/s and an uplink at 145.9 MHz with a 1 kbit/s data rate. Attitude control is via an on-board magnetometer and GPS receiver that provide data for magnetorquer coils which interact with the Earth's magnetosphere to change the satellite's orientation.
