SRMSAT is a Nanosatellite built by faculty and 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.
SRMSAT's primary mission was the development of a nanosatellite platform for future missions. Its secondary mission was monitoring of greenhouse gasses{{cite web |url=https://timesofindia.indiatimes.com/city/chennai/TN-university-plans-centre-for-space-technology/articleshow/10310194.cms|archive-url=https://archive.today/20130126064719/http://articles.timesofindia.indiatimes.com/2011-10-11/chennai/30266441_1_srm-university-nano-satellite-ground-station|url-status=live|archive-date=2013-01-26|work=The Times of India|title=TN university plans centre for space technology }} using an Argus Spectrometer.{{cite web |url=http://thoth.ca/spectrometers.htm |title=Argus Infrared Spectrometers |publisher=Thoth Technology Inc. |url-status=dead |archive-url=https://web.archive.org/web/20131127085357/http://thoth.ca/spectrometers.htm |archive-date=27 November 2013 |df=dmy-all }}

Launch
It was launched from the Indian Space Research Organisation (ISRO)'s Satish Dhawan Space Centre at Sriharikota in October 2011.{{cite news |url=http://timesofindia.indiatimes.com/india/PSLV-C18-carrying-weather-satellite-launched/articleshow/10323961.cms|title=PSLV-C18 carrying weather satellite launched |publisher=Times Of India}} atop a Polar Satellite Launch Vehicle (PSLV) C18 rocket. The launch was a multi-payload mission shared with Megha-Tropiques, VesselSat-1 and Jugnu.{{cite news|url=http://www.thehindu.com/news/national/article2530847.ece|title=PSLV-C18 puts four satellites in orbit|last=Subramanian|first=T.

Parameters
SRMSAT{{cite web |url=https://nssdc.gsfc.nasa.gov/nmc/spacecraft/display.action?id=2011-058D |title=SRMSAT |publisher=NASA}} 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.{{Citation needed|date=March 2023}}
