Description:

• DubaiSat-2 is the second Earth observation satellite of United Arab Emirates Institution for Advanced Science and Technology (EIAST).
• The DubaiSat-2 project is a joint development programme between EIAST and SatrecI of South Korea, in which 16 UAE engineers have been working on the design, development, testing and manufacturing of the satellite. A Hall Effect Propulsion System (HEPS) is installed for orbit control and maintenance. Accurate and agile three-axis attitude control supports precise imaging operations. Dual redundancies are adapted where necessary in the system architecture design to increase reliability of the satellite system.
• DubaiSat-2 is based upon the SpaceEye-1 configuration, which uses a SI-300 bus and the EOS-D camera.
• EOS-D optical payload is a push-broom type camera with 1 m Ground Sampling Distance (GSD) for a panchromatic band and 4 m GSD for four multi-spectral bands. Swath width of the generated image is wider than 12 km. A high performance solid-state recorder is installed to receive, process, store and transmit image data in high speed. During transmission of the stored image data using X-band transmitter, the solid-state recorder compresses, encrypts and encodes the data in real time.

Mission details:

• A Dnepr rocket launched from an ICBM silo at Yasniy in Russia, placed a cluster of 24 satellites in orbit on Nov 21, 2013. Although this is fewer than the ORS-3 launch the day before, the Unisat-5 satellite carries a further eight tiny satellites within it, and one of those (PUCP-Sat) carries a further nested satellite, Pocket-PUCP. Most of the subsatellites were ejected from Unisat-5 between 0810 and 0825 UTC on Nov 21. If all are dispensed successfully, the launch total will be a record 33 satellites.
