Timeline visualization is one of the most important features of the scheduling platform of space missions. This paper proposes a visualization framework that supports various time-dependent data categories. To adapt variable data sources and viewing requirements, a data-method separation mechanism is designed, providing optional drawing methods and visual templates for corresponding data. The drag-and-drop...
The Unified Scheduling Language (USL) is an easy-scheduling feature delivered with the next generation of mission scheduling platform of Beijing Aerospace Control Center. As a domain-specific language, it allows the mission designer define scheduling aspects of mission with natural-like language rather than various machine oriented parameters. Unlike general purpose planning languages such as NDDL...
For designing a general scheduling platform, this part of paper discusses logic and process abstraction that can be implemented to different kind of space missions. A logic model extension solution is given to allow defining specific mission related data patterns with custom manipulation methods. The scheduling elements, requirement, inputs and outputs are organized in one solution for estimation...
In modern software, text is widely used as a common data carrier and more human oriented features are applied in texts. This paper introduces how text analysis technology is implemented in the crew collaboration scheduling system for retrieving and using text information. Regex expression is used as a basic tool for composing text analyzers and interpreters. External data is achieved based on conventional...
Scheduling has always been a bottleneck in space mission control in China. Issues at ideology and feasibility level are essential for plotting a brand new scheduling platform. Through introspection on traditional scheduling methods, theoretical and technical solutions are proposed to support advanced scheduling algorithms and products. Academic issues including theory and methodology are quoted to...
By analyzing the defects of traditional scheduling in space missions, sequential mission scheduling architecture, SMSA, is proposed in this paper to cope with progressively increasing number of state modes of spacecrafts and space missions. The improvements of SMSA lie in both methodologies and ideologies, which make it closer to the core of resource and activity scheduling. The key technologies that...
Crew collaboration schedule is a kind of integrated complex schedule used in space missions to help ground crews and taikonauts perform right task at right time. 12Scheduling was finished by hand in China's early missions costing considerable hours. So an automatic scheduling system was designed in Beijing Aerospace Control Center to substitute manual scheduling.
A flight control strategy is a procedure which is confirmed before mission and executed during mission. It imports mission status and produces commands by calculation. In this paper, started from basic principle, status transition of complex human spaceflight mission is defined as status flow. Thereafter, the thought of strategy making based on status flow is proposed. The status flow and strategy...
