The objective of the S-Net mission is to investigate and demonstrate the inter-satellite communication technology within a distributed an autonomously operating nanosatellite network. As space born systems have become an essential element in facing global challenges such as climate change, disaster management and maritime systems monitoring, rapid response and low cost systems are in high demand.
A key technology to increase the operational efficiency of distributed satellite systems via formations or even autonomous swarms is the miniaturizing of intersatellite communication technology. In cooperation with IQ wireless GmbH, TU Berlin developed an S-band transceiver (SLink)  with 100 kbps crosslink and 1 Mbps downlink capability suitable for accommodation in nanosatellites.

|Abstract||This paper describes the mission design and analysis of an S-band network con-sisting of cooperative nanosatellites (S Net). The mission goal is to demonstrate the inter satellite communication capability of distributed nanosatellites in space. The state-of-the-art network will consist of four nanosatellites each equipped with a miniaturized S-band transceiver which was developed by the Berlin Institute of Technology. This configuration will allow multi-point routing with relatively high data rates compared to other nanosatellite communication experiments. Different inter satellite link protocols will be implemented, tested and verified within the satellite network while simulating various network topologies in orbit. It is expected to show that nanosatellites have the potential to carry out demanding communication applications.|
