EOS-08
Earth observation micro-satellite for ISRO designed to test new technologies for building an Earth observation satellite in a micro-satellite bus. The satellite hoists an Electro-Optical Infrared Payload (EOIR) for Earth observation, a Global Navigation Satellite System-Reflectometry payload (GNSS-R) for weather studies, and an UV Dosimeter to measure UV radiation in low Earth orbit.
Other payload includes the cubesat Space Rickshaw-0.

Орбита явно нерасчётная, что неудивительно, учитывая недоработки всех ступеней.

Цитировать"The third developmental flight of SSLV, the SSLV-D3 with the EOS-08 satellite, has been successfully accomplished. The rocket has placed the spacecraft in a very precise orbit as planned. I find that there are no deviations in the injection conditions. The current indication is that everything is perfect," ISRO Chairman S Somanath said after the successful launch.

Уже 18 августа объекты B. C. D резко подпрыгнули, а А - провалился.: начальные элементы сильно отличались от истины.

С тех пор EOS не менее трёх раз приподнимал орбиту на фоне общего понижения.
