Retrodirective antenna technology for CubeSat networks

In the spring of 2003, the University of Hawaii (UH) began participation in the University NanoSat Program, a multi-university effort sponsored by NASA and the USA Air Force Research Laboratories to encourage small-satellite research and development. Undergraduate engineering students at UH have been involved in small-satellite development for the past two years, particularly for a class of picosatellites known as CubeSat, which has a mass no greater than 1 kg and a volume of 1000 cm/sup 3/.
