Abstract: Delay Tolerant Networks (DTN) is a technique to communicate when there is discontinuous connectivity between endpoints in a data transmission. This method can be useful where a satellite is not in direct visible contact with a ground station. A system can be created with many satellites to establish a communication network to expand the range that satellites can communicate. This system would reduce the requirements on individual nanosatellites satellites as they could utilize dedicated communication satellites to transmit messages. DTN can be used on nanosatellites to develop low mass, power and cost communication subsystem to transmit data. Objectives of this research are to design and demonstrate a novel nanosatellite Delay / Disruption Tolerant Network Topology that uses low mass and power on each individual nanosatellite. The result of implementing this technology is that the mass and power requirements for the communication subsystem are less than when compared to existing traditional communication payloads.
