EDUSAT was put into orbit at 1014 seconds about 5000 km away from
Solar array deployment
Soon after its injection into GTO, the two solar arrays of EDUSAT were automatically deployed. The deployment of the arrays as well as the general health of the satellite were monitored by the ground station of the ISRO Telemetry, Tracking and Command network (ISTRAC) located in the Indonesian island of
Its designated orbital slot is 74 degree East longitude in the
