The Saral Satellite is composed of:
- a spacecraft bus IMS-2 (Small Satellite Bus). This platform, developed by the Indian space agency ISRO, is designed for satellites in the range of about 500 kg at launch.
- a payload developed by CNES composed of the following instruments:
- an altimeter-radiometer Altika (CNES contribution),
- a DORIS system for precise orbit determination (CNES contribution),
- an LRA (Laser Retro-reflector Array) instrument used for precise calibration of other POD instruments, through analysis of laser shots from the ground then reflected by the LRA mirrors (CNES contribution),
- the ARGOS-3 instrument
