Scientific paper

A novel design for a optical intersatellite link terminal is presented. The terminal has a mass of 22 kg, uses approximately 25 W of power, and is extremely compact. Moving mass is also minimized, making it ideal for applications on microgravity platforms. The terminal can support a data rate of 1 Mbps over a distance of 45,000 km, using available 800-nm semiconductor laser diodes. The primary mission is expected to be data relay. However, with projected advances in laser technology, the design will also have application to telecommunications links between geostationary spacecraft and be able to support higher data rates over the baseline mission.
