The first developmental flight of SSLV. The mission target was a circular orbit of altitude 356.2 km with 37.2° inclination. The mission carried two satellite payloads. The 135 kg
EOS 02, an Earth observation satellite and the 8 kg
AzaadiSAT
CubeSat.

Due to sensor failure coupled with shortcomings of onboard software, the stage as well as the two satellite payloads were injected into an unstable transatmospheric Earth orbit measuring 356×76 km and subsequently destroyed upon reentry. According to S. Somanath, an anomaly lasting 2 seconds in one of the accelerometers during second stage separation initiated salvage mode by onboard computer. Guidance, navigation, and control software switched from 'closed loop guidance' where it received real-time feedback from all sensors to an 'open loop guidance' where accelerometer data gets isolated and a predetermined path is followed. [5] This resulted in velocity shortfall from the required 7.3 km/s to 7.2 km/s. Being in salvage mode, Velocity-Trimming Module didn't rectify this shortfall which led to mission failure. | ||||||||

EOS-02: EOS-02 is configured around MicroSat-TD bus platform to demonstrate launch on demand capability with SSLV. It is expected to meet the ever-increasing user demands for cartographic applications, urban and rural management, coastal land use and regulation, utilities mapping, development and various other GIS application. The mission life of the satellite is 9 months.
Global-5 through Global-8 are currently scheduled to be launched in November 2019 on a Small Satellite Launch Vehicle (SSLV) by the Indian Space Research Organization from its Satish Dhawan Space Center
