SRMSAT (Sri Ramaswamy Memorial Satellite) was launched from Sriharikota on 12 October 2011 at 05:30 UT by a PSLV-CA rocket. The satellite is an Indian technology demonstration and Earth observation satellite which was built and will be operated by students of Sri Ramaswamy Memorial University. It weighed 10.9 kg and is intended to monitor greenhouse gases in the Earth's atmosphere. It will also be used to develop future satellites to be operated by the university.

The satellite will use an infrared spectrometer to collect data on the concentration of water vapor and carbon dioxide in specific regions of the atmosphere by studying their absorption spectra. SRMSAT's primary instrument is the spectrometer. It also carries a GPS receiver to aid tracking, and is intended to demonstrate a microelectromechanical inertial measurement unit.
