Запуск успешный.

Запуск успешный.

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

Орбита явно нерасчётная

Непонятно. Расчётная круговая 475 км, фактическая приведена выше.

"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.
