  1. Based on the theory of software architecture, the hierarchical structure is used for designing the software system because the aocs demands real - time and high reliability. the integrated environment for software cross - development of vxworks is used for simulating the schedule of several multi - tasks, the managing of work mode and the communication among the modules. an approach of software architecture for the attitude and orbit control system of satellite is developed in this paper, which is based on a deep study and analysis of modern software techniques

    本文運用軟體體系結構的理論，通過對多種軟體體系結構的分析比較，針對衛星姿軌控系統實時、高可靠、復雜等特點，採用層次結構方案進行了體系結構設計，並運用實時操作系統vxworks的集成開發環境，完成了姿軌控系統多任務調度管理、工作模式管理和應用模塊間相互通信的模擬實踐。
  2. Each mission had a satellite designed to photograph the surface of mars from orbit, and to act as a communication relay for the viking lander that each mission carried

    每次任務都發射一枚具備從火星軌道拍攝火星表面能力的人造衛星，同時充當與海盜登陸者進行聯絡的中間站。
  3. Methods of in - orbit testing for communication satellite payload performances

    通信衛星有效載荷性能的在軌測試方法
  4. The advantages of using leo satellite are as following : on the one hand the satellite orbit is low, so the transmission delay is short, the power loss is small ; on the other hand the development of cell communication, multi - access, frequency multiplex and etc also provide a technique guarantee to the leo satellite - mobile - telecommunication. so the leo system is considered to be a satellite - mobile - communication system with a great future

    低軌道衛星是一種運行於1000公里左右的高空中的人造衛星，利用leo衛星實現個人通信的優點在於：一方面衛星的軌道高度低，使得傳輸延時短、路徑損耗小，多個衛星組成的星座可實現真正的全球覆蓋，頻率復用更有效：另一方面蜂窩通信、多址、點波束、頻率復用等技術的發展也為低軌道衛星移動通信提供了技術保障。
  5. Influence of doppler shift on narrow - band interference suppression in low - orbit satellite communication

    高速移動通信中的多普勒分集技術
  6. Analysis of termination - concerned qos performance in nongeostationary orbit satellite communication systems

    非靜止軌道衛星系統考慮通信中斷的服務質量分析
  7. Case 1 : when there is no relative measurement, each satellite uses its own on - board attitude sensors to determine its attitude, and exchange the information through the communication link between formation satellites, and then the relative attitude is determined through simple mathematical operation. case 2 : based on the range measurements of gps like sensors, using two - point measurement of the relative orbit state to establish relative orbit and attitude kinematics and measuring equations. and state estimation is achieved through the extended kalman filter technology and unscented kalman filter technology, respectively

    方案一，在星間無相對測量時，由衛星自身攜帶的姿態敏感器實現單星高精度姿態確定，利用星間通信鏈路進行信息交互，通過簡單的數學計算獲得星間相對姿態;方案二，利用類gps相對測量，建立了編隊衛星相對軌道運動和相對姿態運動模型及相對距離測量方程，推導了兩點相對軌道運動模型，設計了擴展卡爾曼濾波器及uscented卡爾曼濾波器，對相對位置、速度和姿態進行估計。
