Integrated navigation and communication system for use in distributed spacecraft systems

摘要

An integrated navigation and communication system that enables distributed spacecraft system operations. The system is a modular, extensible system that supports science operations among multiple, distributed spacecraft by implementing the essential functions of navigation, communication and control. Distributed spacecraft systems, also called formation flying systems, extend the capabilities of single-spacecraft missions by providing a platform for complex sensing tasks, including multipoint observation, co-observation, and distributed apertures. To accomplish these tasks, the system enables spacecrafts within a distributed spacecraft system to communicate science and coordination information, to determine relative position, velocity and time for command and control operations, and to operate in a coordinated manner to achieve common mission goals.
