Abstract | The paper presents the mission and system design of the S-Net mission, which consists of four nanosatellites to demonstrate intersatellite communication in S-band. The goal is to demonstrate multipoint to multipoint communication with high data rates and optimized communication protocols to push further the technological boundary of nanosatellites. To overcome the cross-communication limitations of a nanosatellite, the Technical University of Berlin developed an S-band (2.0-2.3 GHz) transceiver with 100 kbps crosslink and 1 Mbps downlink capability suitable for nanosatellites. Modern transmission techniques such as Adaptive Modulation and Coding (AMC) with Turbo and convolutional coding and up to APSK8 were implemented and tested on ground. The transceiver accommodates the physical layer and data link layer while the satellite controller is responsible for the network layer. Each nanosatellite will be equipped with the above mentioned S-band transceiver. Hence a mission analysis as well as the design overview of the space segment and ground segment will be described. Different network architecture and corresponding routing algorithm will be demonstrated and verified within the mission. |
