Definition and Design of an Experiment to Test Raster Scanning with RotatingUnbalanced-Mass Devices on Gimbaled Payloads

摘要

An experiment designed to test the feasibility of using rotating unbalanced-mass(RUM) devices for line and raster scanning gimbaled payloads, while expending very little power is described. The experiment is configured for ground-based testing, but the scan concept is applicable to ground-based, balloon-borne, and space-based payloads, as well as free-flying spacecraft. The servos used in scanning are defined; the electronic hardware is specified; and a computer simulation model of the system is described. Simulation results are presented that predict system performance and verify the servo designs.
