Abstract

A lasercom pointing, acquisition, and tracking (PAT) testbed has been developed at The Aerospace Corporation. The current setup represents a GEO-to-GEO link, but depending on the target PAT subsystem, this testbed can be reconfigured. No communication aspects are currently implemented. The system operates in small beam space and consists of a far field space simulator, and two identical lasercom terminals implemented with representative hardware (fast steering mirrors, optical detectors, etc.) and differentiated only by two laser sources operating at visible wavelengths of 473 nm and 633 nm. In this paper, the design process will be examined, and aspects of the pointing accuracy will be discussed.
