RazakSAT
RazakSat is a Malaysian Earth observation satellite, which carries a high resolution camera and was taken on 14 July 2009 at 3:35 UTC with a rocket Falcon 1 from the island Omelek into orbit.
Details
It is in a RazakSat in Malaysia, developed and built in collaboration with the South Korean company Satreci satellites and also the first commercial payload of the rocket Falcon 1, which is operated by the company, SpaceX. The start was against the plan by more than four hours moved because there had been a minor problem in the helium system of the carrier and traversed some rain showers. Razaksat should have been flying on the fourth Falcon 1 was but after three false starts of the carrier delayed for safety reasons by a further test flight. Three minutes after the start of the payload fairing was separated, and about one hour after the start of the satellite is separated from the launcher and placed in its final orbit. The hexagonal, a good meter high and about 180 kg satellite carries a camera with a resolution of 2.5 m per pixel in the black and white area and 5.5 m with color images at a swath width of 20 km. It was built on the basis of the satellite bus SI -200. The three- axis stabilization of the satellite is (300 watt EOL) ensured by four reaction wheels and the power supply by gallium arsenide / germanium solar cells on a honeycomb substrate and nickel -cadmium batteries with a capacity of 18 Ah. The remote control of the satellite is carried out by an S -band connection, and the data transmission of the user data in the X-band of up to 30 Mbits per second, the data is latched on a 32 Gbit large solid state drive board. Due to the completed almost along the equator start RazakSAT flies with an inclination of only nine degrees, which he flies up to a dozen times a day Malaysia, more than any other earth observation satellites. The life of three years are planned.
The pictures of RazakSAT to scientists, commercial customers and authorities are available, the use for urban planning, crop monitoring, environmental monitoring, forestry and cartography are planned.
