Abstract

We are developing an inter-satellite omnidirectional optical communicator (ISOC) that will enable gigabit per second data rates over distances up to 1000 km in free space. Key features of the ISOC include its high data rates and its ability to maintain multiple simultaneous links with other spacecraft. In this paper we present design considerations for the ISOC, including selection of the mission-appropriate geometry, telescope design, receiver design, as well as beam pointing considerations. We also present experimental results obtained with the ISOC prototype. In addition, we present design considerations for a low-Earth-Orbit mission where four ISOC-furnished CubeSats form a swarm suitable for remote sensing. We believe the ISOC could be a technology enabler for future constellation and formation flying CubeSat missions for Remote Sensing.
