Design and validation of flight dynamics system

Abstract

This paper presents the architecture design of flight dynamics system (FDS) known as "EMERALD" developed by Geo-Informatics and Space Technology Development Agency (GISTDA) and Mahanakorn University of Technology (MUT). The capability of the system enables to provide the state vector of a satellite, mission analysis, orbit events and mission monitoring. The methodologies of orbit determination and event prediction modules implemented for mission management are presented and the validation is performed by comparing the prediction results with the performance of the mission operation. As a result of the implementation, the reduction of the operation time consumption is improved significantly and the prediction performance is high accurate and reliable when comparing with previous FDS (Quartz) developed by EADS ASTRIUM.

Development of Space Traffic Management System: ZIRCON

“…Based on GISTDA's experiences that success to develop and implement in-house flight software dynamics known as "EMERALD" [2][3][4][5][6][7][8][9], the accuracy of orbital prediction consists of 2 main factors in order to high accuracy to define TCA and miss distance. Firstly, perturbation forces in ZIRCON are decided to consider gravitation potential, third body perturbations (the sun and moon), solar radiation pressure and atmospheric drag.…”
