1. Main MCS

The Main MCS monitors and controls the satellite. It is located at EIAST’s ground station in Dubai, UAE. The Main MCS performs satellite operation planning, which includes imaging and download scenarios, mission timeline, and orbit maintenance operation. It has direct interface with the Subsidiary MCS, Main IRPS, and EIAST’s ground station antenna system. All imaging and downloading requests are received from Main IRPS.

2. Subsidiary MCS

The Subsidiary MCS is located in ground stations other than EIAST’s ground station. It is connected directly to the Main MCS and the antenna system of the ground station where it is located. The Subsidiary MCS relays telecommands and telemetries between Main MCS and Dubaisat-2 through TCP/IP connection. The Subsidiary MCS does not perform any satellite operation planning tasks. The main purpose of the Subsidiary MCS is to utilize the satellite when it is not over Dubai.

3. Main IRPS

The Main IRPS is located only at EIAST’s ground station in Dubai, UAE. It has direct interface with Main MCS, Customer IRPS, and the end users. The Main IRPS generates schedule requests, which includes imaging and download schedules. It also archives image and ancillary data for product generation and distribution. Ancillary data consists of attitude and ephemeris data.

Main IRPS receives imaging requests from Customer IRPS and imaging orders from end users. It prioritizes and schedules the received requests and orders accordingly, then generates and transmits schedule request to the Main MCS for satellite operation planning.

4. Customer IRPS

The Customer IRPS is located at any ground station, other than EIAST’s ground station, that desires to receive images data directly from DubaiSat-2. It has direct interface only with Main IRPS and the ground station’s end users. The Customer IRPS archive image and ancillary data for product generation and distribution. It receives imaging orders from end users and sends imaging request to the Main IRPS. Image request is generated based on the received imaging orders. When installing Customer IRPS, geographical location of the customer’s facility is taken into consideration to avoid overlap with other ground stations.

5. Antenna System

The Main MCS and Main IRPS share the same antenna system. The primary antenna used for DubaiSat-2 mission operation is an 11.28 meter S/X-band antenna located at EIAST’s main facility in Dubai, UAE.
