Concept
DubaiSat-1
Summary
DubaiSat-1 (دبي سات-1) is a remote sensing Earth observation satellite built by the Emirates Institution for Advanced Science and Technology (EIAST) under an agreement with Satrec Initiative, a satellite manufacturing company in South Korea.
DubaiSat-1 was launched on 29 July 2009 into a 680 km altitude sun-synchronous polar orbit from the Baikonur launch site in Kazakhstan, along with several other satellites on board the Dnepr launch vehicle.
DubaiSat-1 observes the earth at a Low Earth orbit (LEO) and generates high-resolution optical images at 2.5 m in panchromatic (black-and-white) and at 5 m in (colour) bands. These images provide decision makers in the UAE as well as EIAST clients with a valuable tool for a wide range of applications including infrastructure development, urban planning, and environment monitoring and protection. DubaiSat-1 images are also useful for promoting geosciences and remote sensing research in the region, and for supporting different scientific disciplines in private and academic sectors.
For example, DubaiSat-1 images have been used, to monitor progress on The World megaproject, Palm Islands, and the Al Maktoum International Airport.
The United Nations also used DubaiSat-1 images to monitor relief efforts following the 2011 Tōhoku earthquake and tsunami in Japan.
The satellite accommodates two main payloads. The primary payload is the Dubai Medium Aperture Camera (DMAC), and the secondary and experimental payload, the Space Radiation Monitor (SRM).
The DMAC system is pushbroom imaging system with one panchromatic and four multi-spectral imaging channels. It also consists of an Electro-Optical Subsystem and the Payload Management Subsystem. The Electro-Optical Subsystem has a telescope, a focal plane assembly, and a Signal Processing Module. The Payload Management Subsystem consists of the Thermal and Power Module and the Mass storage and Control Module.
The Space Radiation Monitor, the secondary and experimental payload, is capable of measuring the total ionizing dose from the charged particles at the orbits of satellites.
