Its architecture is designed to accommodate an Earth observation and/or science payload. 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.
