1979年6月7日,苏联帮助印度发射了第一颗地球观测卫星,该卫星进入512×557公里的轨道,倾角为50.7度,周期为95.15分,与预定轨道(525公里高,51度倾角)非常接近。由于星上某些设备的调试迟缓以及印度在去年遭到的国内困难,尽管有苏联技术人员的协助,地球观测卫星仍推迟发射将近一年。该卫星重量为442公斤,设计寿命为一年。星上装有一台两通道的电视摄像机和一台两通道的 On June 7, 1979, the Soviet Union helped India launch the first earth observation satellite that entered a 512 × 557-kilometer orbit at an inclination of 50.7 degrees with a periodicity of 95.15 minutes, which was in line with the planned orbit (525 kilometers high and 51 degrees inclination )very close. Earth observation satellites have been delayed for nearly a year in spite of the slow commissioning of certain devices on the planet and the domestic difficulties India suffered last year, despite the assistance of Soviet technicians. The satellite weighs 442 kg and has a design life of one year. A two-channel TV camera and a two-channel TV set on the satellite
