Technology Experiment Satellite (TES) is Working Well

The Technology Experiment Satellite, TES, which was launched by ISRO's Polar Satellite Launch Vehicle, PSLV-C3, from Sriharikota yesterday (October 22, 2001) is functioning well. The tests on various subsystems like telemetry, command and power have been completed. The Satellite Positioning System (SPS), which helps in accurate determination of the satellite's location, has also been tested. The data handling systems are planned to be tested in the coming days before the camera payload on board is turned on.
It may be noted that, immediately after its injection into orbit by PSLV yesterday, the two solar panels of the satellite were automatically deployed and the satellite was put in three axes stabilisation mode using Reaction Wheels as per plan. The satellite is being monitored from the Spacecraft Control Centre (SCC) of ISRO Telemetry Tracking and Command Network (ISTRAC) at Bangalore along with its network of stations at Lucknow, Mauritius and Bearslake in Russia.

The two other satellites, PROBA of Belgium and BIRD of Germany, which were launched by PSLV along with India's TES, are also reported to be functioning well.
