First flight of SSLV.
The separation of the second stage produced higher than expected vibrations, which caused Inertial Navigation System accelerometers to be saturated. Flight software then erroneously switched to "salvage mission mode", the 4th stage was commanded not to ignite and the satellites was deployed into an unstable 360 x 75 km orbit, which they quickly re-enter.
EOS-02 is an earth observation satellite designed and realised by ISRO. This microsat series satellite offers advanced optical remote sensing operating in infra-red band with high spatial resolution. The bus configuration is derived from IMS-1 bus.
AzaadiSAT is a 8U Cubesat weighing around 8 kg. It carries 75 different payloads each weighing around 50 grams and conducting femto-experiments. The payloads include a UHF-VHF Transponder working in ham radio frequency to enable voice and data transmission for amateur radio operators, a solid state PIN diode-based Radiation counter to measure the ionising radiation in its orbit, a long-range transponder and a selfie camera.
