DubaiSat 1 is the United Arab Emirates' first Earth observation satellite .
Mission and Payload
It was launched on July 29, 2009 with a Ukrainian Dnepr launcher at 18:46 UTC from Baikonur together with two satellites of the global disaster control system DMC , the Spanish Deimos-1 and the British UK-DMC 2 . In addition, the Spanish technology satellite NanoSat 1B and the Argentine communication satellites AprizeSat-3 and 4 (each around 12 kg) were brought into space as planned. The satellites will orbit the earth at an altitude of 680 km on a sun-synchronous orbit at a speed of 27,000 km / h. DubaiSat 1 was developed by the Emirates Institute for Advanced Science and Technology (EIAST) in collaboration with the South Korean Satrec Initiative GmbH in Daejeon for 50 million euros (184 million Dh ) and had a planned lifespan of five years. The satellite has an optical imaging system with a black and white resolution of five meters and a resolution in the multispectral range (four channels, red, green, blue and NIR ) of ten meters. There is also a radiometer on board to determine the ionizing radiation. DubaiSat 1's images are intended to be used for urban planning, scientific research, telecommunications, transportation, construction and mapping. The satellite is based on the South Korean SI-200 satellite bus and weighs around 200 kg. It has a cylindrical floor plan with a diameter of 1.20 meters and a height of 1.35 meters. The energy supply is ensured by three solar cell booms with around 330 watts and three batteries of 18 Ah. The telemetry transmission takes place via two S-band receivers and transmitters (2 watt power), the data transmission of the images via two transmitters with 5 watt power each, whose signals are QPSK- modulated.
The successor DubaiSat 2 was launched on November 21, 2013. In 2016, DubaiSat 1 went out of operation and is only occasionally contacted for tests.
