摘要

The China-Brazil Earth Resources Satellite (CBERS) project has necessitated some rethinking of traditional Flight Dynamics Software (FDS) system design and development strategies. These methodologies have been towards an integrated approach for Flight Dynamics Software System. These aspects became relevant during the design of FDS for CBERS mission. Eventually FDS was developed for flight dynamics analysis and satellite mission support. The support requirements for mission are entities like performing orbit determination, maneuver analysis, attitude determination, satellite ephemeris generation, and orbit information. Hitherto these activities were performed through groups of tasks and analysts acting in parallel on several types of computer platforms, which led to many operational difficulties. In this scenario an integrated approach along with visual interfaces to provide quick and near real time decision-oriented flight dynamics software is needed. Towards this goal, an integrated software design is being done. A strong need has existed for rigorous quality assurance methods that account for the unique nature and environment of satellite flight dynamics support. This paper describes the product and process assurance methodologies applied to each phase of flight dynamics mission support lifecycle. It is now considered object-oriented programming as an integral part of modern symbolic processing systems. The Object Oriented Design (OOD) approach for flight dynamics system is of a class structure with existing flight dynamics models to produce a very complete, yet re-configurable prototyping tool. The C++ OOD code addresses the development of OOD classes for orbit and attitude determination and maneuver planning and execution. The conceptualization of OO methodology for flight dynamics along with the specific software design applied to CBERS is presented.
