Technology Experiment Satellite (TES) is an Indian remote sensing and photo-reconnaissance satellite.

Launch

Technology Experiment Satellite (TES) was launched by the

Indian Space Research Organisation (ISRO). TES was successfully placed in a 572 km Sun-synchronous orbit on 22 October 2001 using PSLV-C3. PSLV-C3 also deployed two additional satellites: PROBA, a Belgian satellite, and BIRD
, a German satellite.

Mission

The technologies demonstrated in TES are

attitude and orbit control system, high torque reaction wheels, new reaction control system with optimised thrusters and a single propellant tank, light weight spacecraft structure, solid state recorder, X-band
phased array antenna, improved satellite positioning system, miniaturised TTC and power system and, two-mirror-on-axis camera optics.

TES has a pan chromatic camera for remote sensing. The camera is which is capable of producing images of one metre resolution. One metre resolution means the camera is able to distinguish between two objects which are separated at least a metre.

The launch of TES made India the second country in the world after the United States that can commercially offer images with one metre resolution.[2] It is used for remote sensing of civilian areas, mapping industry and geographical information services. TES, helped the US Army with high-resolution images during the 11 September 2001 counter-terrorism offensive against the Taliban.
