System Aspects on Clusters of Small Sensor Satellites
ABSTRACT
A single large satellite can be replaced with a configuration of several smaller satellites which together perform the same
function as a larger satellite. The report deals with how such ‘formation-flying’ satellites can be used for military applications
and what sensor system can be used. Sensor systems discussed are SAR, SIGINT (passive interception), and optical systems.
An overview of a few of the multitude of on-going projects around the world is given. A short review of orbits for
formation-flying satellites is also given. The advantages with systems of satellites in comparison to solitary satellites are
presented. One of the main ideas behind the concept of formation flying is that by using several small satellites the costs are
reduced and the reliability of the system is increased. The costs may diminished when the microtechnology is mature enough
for mass production of microsatellites.
