Abstract

Precise formation flying (PFF) missions require formation acquisition and maintenance through interactions among spacecraft by inter-satellite communication and relative navigation. That requires the network architecture to satisfy dedicated system constraints of time-criticality for updating navigation measurements and flexibility for implementation across various phases of mission operations. Potentially applicable architectures that combine different multiple access technologies, half-duplex/full duplex configurations, and network topologies are discussed and evaluated. Half-duplex CDMA with roles rotating among all spacecraft is shown more suitable and efficient for PFF missions. Its limitation in terms of multiple access interference is analyzed as well.
