Brassboard Acquisition and Tracking Requirements Study.
Abstract
The objective of this study was to define the hardware design requirements of a brassboard acquisition and tracking subsystem, based on the preliminary subsystem design documented in SAMSO-TR-71-251. The work includes detailed design for the acquisition and tracking subsystem, simulation equipment, and precision instrumentation equipment; and detailed descriptions of the integration of components and experiment test plan. The brassboard acquisition and tracking package is configured to verify the performance for all three primary stations; low altitude satellite, synchronous satellite, and ground. It is capable of demonstrating the total automatic sequence of operations required to detect and sense initial errors as large as + or - 8.75 mrad, align the optical boresight and point a simulated communication laser to within + or - 50 micro-rad using 10 pps information, change modes from acquisition to tracking, and track and fine point with an error of less than 1 micro-rad. The precision instrumentation equipment is designed to measure the pointing capability of the brassboard acquisition and tracking subsystem to a fraction of the 1 micro-rad tracking error. The simulation equipment is configured to provide beacon laser signals, realistic satellite rotations, satellite flexure effects, and orbital kinematic motions of the line-of-sight during acquisition and tracking.
