Operational validation of the flight dynamics system for COMS satellite

Abstract

As a multi-mission GEO satellite, COMS has three payloads including Ka-band communications, geostationary ocean color imager, and meteorological imager. COMS flight dynamics system provides the general on-station functions such as orbit determination, orbit prediction, event prediction, station-keeping maneuver planning, station-relocation maneuver planning, and fuel accounting. There are some specific flight dynamics functions to operate the Eurostar 3000 spacecraft bus such as wheel off-loading management, oscillator updating management, and on-station attitude reacquisition management. In this paper, operational validation of the major functions in COMS flight dynamics system is presented for the first six month of operations period.

Overview of the Flight Dynamics Subsystem for Korea Pathfinder Lunar Orbiter Mission

“…At the same time, in-house software, especially the core algorithm related to the flight dynamics of the planetary mission, is now being developed based on KARI's heritage of past LEO and GEO missions [34][35][36][37][38][39][40][41][42] to prepare for future space exploration in Korea. During the operation of the COTS-based FDS, the performance of the developed in-house software will also be validated using the real navigation and flight data of the KPLO.…”
