(First Indian Experimental Satellite)
Launch Date : April 19, 1975
Weight : 360 kg
Orbit : 619 x 562 km inclined at 50.7 deg
Lauched by : Soviet Intercosmos rocket.
Objectives : The objectives of this project were to indigenously
design and fabricate a space-worthy satellite system and evaluate its
perfromance in orbitr.
* to evolve the methodology of conducting a series of complex operations on the
satellite in its orbital phasei.
* to set up ground-based receiving, transmitting and tracking systems
and to establish infrastructure for the fabrication of spacecraft systems.
The exercise also provided an opportunity to conduct investigations in the area
of spcae sciences. The satellite carried three experiments, one each in X-Ray
Astronomy, Solar Physics and Aeronomy.
