Spacecraft Angular Rate Reference System

Akira Murakami

Abstract:	The objective of this paper is to describe the Angular Rate Reference System (ARRS) so its principle can be adopted by the satellite program to determine accurately, for instance an earthquake epicenter. The ARRS consists of two major processors, the Reaction Wheel Control Processor (RWCP) and the Angular Rate Processor (ARP) which perform the following major functions. The RWCP corrects spacecraft (SC) axes rotation and deviation which are caused by the internal and external torque (4)(Figure-1). The ARP computes the average real Earth Center Earth Fix (ECEF) Range and the average real SC flight veracity every second, then transmits the data to the Ground Station to plot the real equipotential orbit and to analyze the ARRS performances.
