Technology Experiment Satellite (TES) is Indian remote sensing and photo-reconnaissance satellite. The 1108 kg satellite carries a one-meter resolution panchromatic camera is an experimental satellite to demonstrate and validate, in orbit, technologies that could be used in the future satellites of Indian Space Research Organisation (ISRO). It was successfully placed in 572 km Sun-synchronous orbit on 22 October 2001 using the PSLV-C3. The PSLV-C3 also injected two more satellites: PROBA, a Belgian satellite and BIRD, a German satellite.
TES was lifted into orbit during the mission ‘PSLV | TES’, on board a PSLV space rocket.
The launch took place on Oct. 22, 2001, 4:53 a.m. from Satish Dhawan Space Centre First Launch Pad.
