ResourceSat-2

ResourceSat -2 is an Indian earth observation satellite from the Indian Remote Sensing series of ISRO.

It was on April 20, 2011 at 04:42 UTC with a PSLV rocket from Satish Dhawan Space Centre together with the small satellite YouthSat ( Indian -Russian, 92 kg) and X - SAT ( Singapore, 106 kg) in a circular polar and sun-synchronous orbit brought with an inclination of about 98.7 degrees. The separation of the rocket was made after a total flight time of about 1080 seconds at an altitude of about 827 kilometers. It is intended to support scientists in the measurement of soil contamination, monitoring of water resources and land use, as well as provide data for the security agencies. He also bears an experimental monitoring and identification system (AIS = Automatic Identification System) for ships to collect their position, speed and other information. This was built by ComDev from Canada. The life of five years are expected.

The satellite carries three cameras operating in the visible and infrared range and deliver a maximum resolution of 5.8 meters. They are enhanced versions of the cameras that were used in the predecessor, launched in 2003 ResourceSat -1. So was increased from 23 to 70 km for the high-resolution line scanner LISS -4 (Linear Imaging Self Scanner ) the swath width.

The satellite used for stabilizing reaction wheels, Magnetic torquers and hydrazine thrusters. The solar cells provide a power of 1250 W ( End Of Life ) and are supplemented by two nickel - cadmium batteries of 24 Ah capacity. The storage of the captured images is carried out on two solid- state drives with a capacity of 200 gigabytes.
