DubaiSat-2 is an electro-optical Earth observation satellite built by the Emirates Institution for Advanced Science and Technology under an agreement with Satrec Initiative, a satellite manufacturing company in South Korea. EIAST’s objective with DubaiSat-2 is to provide electro-optical images, that can be commercialized, for users within the United Arab Emirates and beyond and to develop and implement new technologies not used in DubaiSat-1. EIAST also intends to continue manpower training for the UAE’s space program. 16 UAE engineers have been working on the design, development, testing and manufacturing of the satellite. The participation of the UAE engineers, who are currently working in South Korea, has increased by 100 per cent from the DubaiSat-1 project and it is hoped that this will take EIAST to the next level in satellite development.
The space segment consists of a spacecraft bus and an electro-optical payload. The electro-optical payload is a push-broom camera with Time Delay Integration (TDI) sensors (1 panchromatic and 4 multi-spectral bands). DubaiSat-2 is designed for a sun-synchronous orbit of 600 km, with a spatial resolution of 1m PAN and 4m Multispectral (MS), and a Swath of 12.2 km.
The modules in the satellite use two CAN Bus networks to communicate with each other and it has the capacity to store approximately 17,000 km2 of image data. It also includes an experimental propulsion system for orbit correction and maintenance. The satellite’s expected lifetime is at least five years.
