Free-Space Laser Communications XXXII.
The development of large Low Earth Orbit (LEO) satellite constellations is driving the need for autonomous satellite orbit determination. The present state-of-the art is the use of global positioning system (GPS) receivers on individual satellites th

The most important single attribute of a Laser Communications Ground Station is the receiver aperture area to maximize the received signal and hence signal-to-noise ratio (SNR). However, the larger the aperture, the greater the negative effects impar

The Air Force Research Laboratory is developing a space-based sparse-array aperture system, called TechSat 21. The TechSat 21 experiment is a cluster of three satellites that will fly in formation and operate cooperatively to perform the function of

This paper investigates the performance of a spaceborne, distributed aperture system operating in a moving target indication (MTI) mode. A cluster of microsatellites, orbiting in proximity, house the antenna subapertures of the distributed array; the
