“…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.…”

In near future, commercial companies have proposed to launch the extreme large constellation of small to medium-sized satellites over new 20,000 satellites in orbit. As a result, satellite operators will face a new challenge and have to prepare some solutions to mitigate huge potential collision risks. Under current practices, operators receive collision warning messages (Conjunction Data Messages: CDMs) generated by the Combined Space Operations Center (CSpOC). It is possibly to receive huge conjunctions that exceed warning threshold control each day but many of them are false conjunctions because the result of a combination of inaccuracies in the sensor measurements, predicting error and especially inadequacy of satellite information (e.g., GPS data and satellite size) To reduce the false CDMs and effectively mitigate the potential risk in time, space traffic management system can minimize the problems. The key system capabilities are able to automatically screen potential risky objects and provide an analysis tool to decide effective maneuver planning. As a result, GISTDA initiates the project to develop the space traffic management system known as “ZIRCON” to monitor and mitigate the risk of GISTDA’s satellites and future satellites (e.g., THEOS2 project). This paper presents the operational collision avoidance process and algorithm analysis of space traffic management system. The accuracy of analysis results is validated by comparing the analyzed results of CSpOC and Space Data Association (SDA) serving the commercial space sector to monitor and provide warning message for membership. The last section describes the future development planning and services for satellite operators.

“…This module is processed when we receive a notification (Conjunction Data Message: CDM) by Joint Space Operations Center (JSpOC). Finally, the de-orbit module [5] is capable of analyzing a strategy to re-entry to the Earth by performing the guidelines of Inter-Agency Debris Coordination Committee (IADC) [6] that post-mission orbit lifetime no longer than 25 years is in active regions. All analyzed results of all modules will be transferred to store in the database of the ground control system.…”

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.

1 Самарский государственный аэрокосмический университет имени академика С.П. Королёва (национальный исследовательский университет)2 Северо-западный политехнический университет, г. Сиань, КНР Анализируется устойчивость движения космической тросовой системы с атмосферным зондом. Рассматривается устойчивость положений равновесия тросовой системы вблизи местной вертикали (ста-тическая устойчивость) и при её развёртывании (динамическая устойчивость). Тросовая система состоит из базового космического аппарата, с которого производится выпуск троса, и атмосферного зонда. Мето-дом Лагранжа получена математическая модель движения тросовой системы в подвижной орбитальной системе координат с учётом аэродинамических сил, действующих на космический аппарат и зонд. Полу-чены условия устойчивости движения тросовой системы относительно местной вертикали. Аналитиче-ский анализ подтверждается численными примерами.Космическая тросовая система, атмосферный зонд, статическая устойчивость, динамическая устойчивость, условия устойчивости, метод фазовой плоскости, численный анализ.
