PISAT

The Full Form Of PISat is PESIT Imaging Satellite.

PIsat  is a remote sensing nanosatellite developed by the PES Institute of Technology, Bengaluru. 

The satellite was launched on 26 September 2016 by ISRO using the PSLV-C35 rocket.

PiSAT is 25×26×18 centimetres in size and weighs 5.3 Kilograms and carries an image camera that can capture pictures with 80-meter resolution. 

The satellite body is covered with 52 Advanced Triple Junction solar cells This solar cells having 13 strings to deliver a maximum power of 13 Watts fed to a 5.2 Amp-hour battery.

The PiSAT spacecraft is three-axis stabilized using a magnetic control system. Attitude information is collected by four sun sensors and a three-axis stabilized system using gyro system and magnetometer unit.

Power converters deliver 5 and 3.3-Volt power supplies to the satellite’s electronics which require a continuous power of 4.5 Watts to stay alive.

PISAT is a Low-cost Imaging satellite with pointing accuracy of ±5 degrees about Yaw, Roll and Pitch axis. 

This satellite was launched at an altitude of 720 kilometres with an inclination of 97.886 degrees and in Polar sun synchronous orbit.

This satellite used System engineering concepts in the development of PISAT and students has benefited in getting good hands-on experience in system engineering.

PISAT is designed to receive S‐band modulated signal, which is demodulated and extracted from the ground station.
