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
multispectral (colour) bands. These images provide decision makers in the UAE as well as MBRSC 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. 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. The instrument utilizes four
p-type Metal-Oxide-Semiconductor Field Effects Transistors (MOSFETs). These devices measure the current-voltage characteristics of the satellite. Subsequent analysis will allow measurements of the amount of cumulative ionizing dose, and of the total ionizing dose of the devices. ==Structure==
