Attitude control
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.
