SRMSAT is a Nanosatellite built by students at Sri Ramaswamy Memorial University(SRM Institute of Science and Technology,Chennai) in India. The satellite is an Indian Technology demonstration and Earth observation satellite which is operated by the SRM Institute of Science and Technology. This nanosatellite was 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 had a design life of one year, but is still working As of October 2017[update] and can be tracked easily on n2yo.com 
It was launched from the Indian Space Research Organisation (ISRO)'s Satish Dhawan Space Centre at Sriharikota in October 2011. atop a Polar Satellite Launch Vehicle (PSLV) C18 rocket. 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 Ultra high frequency (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 solar cell management system (SCDM), an on-board magnetometer and Global Positioning System (GPS) receiver that provide data for magnetorquer coils which interact with the Earth's magnetosphere to change the satellite's orientation.
