摘要

To meet the 0.012 deg, 3-sigma, per axis, absolute bus attitude knowledge requirement flown-down from Remote Sensing Instrument (RSI) for meeting its geo-location accuracy, the micro-Advanced Stellar Compass (mu-ASC) consisting of three Camera Head Units (CHUs) along with four single-axis fiber-optics gyros is mounted on a stable optical bench common to the RSI structure. The mu-ASC is a highly advanced and fully autonomous star tracker produced by the Measurement & Instrument System (MIS) Section of the Orsted Department of the Technical University of Denmark (DTU). The gyroscopes considered in this mission are the fiber-optics rate sensors, mu- FORS3UC, manufactured by Litef, a Northrop Grumman branch in Germany. The mu-FORS3UC is originally designed to meet the requirements of a wide range of air, land, and sea applications, and was later certified by NSPO for space applications after a series of environmental tests.
