AOCS's Units Functional Tes t Met hod Res ul t For Small Satellite

摘要

A KOMPSAT-2 (Korea Multi Purpose SATellite-2) satellite, developed by KARI (Korea Aerospace Research Institute) as a small satellite, consists of several subsystems which are EPS(Electrical Power Subsystem), TC&R(Telemetry Command & Range Subsystem) and AOCS(Attitude Orbit Control Subsystem). Regarding to AOCS part, the one of the subsystems, it has good accurate sensors and actuators due to a 1meter FOV of required imagining data. AOCS hardware – Gyro, Sun Sensor, Star Tracker, Reaction Wheel, SADA, Earth Sensor, MTQ, Magnetometer, Thruster, etc - needs to perform some tests such as function, polarity and performance test in the AIT level in order to verify that all hardware units generate their ability in the requirement. Those are tested by GSE(Ground Support Equipment) and Test-aids. In this paper, it introduces and describes the AOCS part of KOMPSAT-2 and its test methods and results.
