Abstract
The Coral bus design meets the stringent pointing/slew requirements of Electro-Optical (EO) or Space Situational Awareness (SSA) missions, as well as the higher payload power requirements for Communications or Synthetic Aperture Radar (SAR) missions. The power design features two deployed solar array wings along with a Lithium-Ion battery that provides significant payload power during all mission timeframes. The Attitude Determination and Control Subsystem (ADCS) features excellent agility/stability performance and excellent pointing accuracy performance through the use of a Miniature Star Tracker (MST) developed by CAA. Coral’s Communications system features a high data rate transceiver for support to these specialized missions. Coral’s Avionics subsystem communicates over a high bandwidth, standardized bus that provides a number of external interface options to the payload. The Command and Data Handling (C&DH) software architecture allows rapid integration of any payload hardware or software option with little or no impact to the bus architecture design at any point within the program timeline. Coral facilitates rapid assembly and disassembly of the Coral spacecraft and provides clear access to external interfaces at all times. The Coral bus also provides the ability to be easily upgraded for additional capabilities (e.g., addition of propulsion and power, downlink, and encryption upgrades).
