汽車、火車、艦船、飛機等運動載體的位置和姿態不斷的在變化，要保持與衛星的通訊聯系和接收衛星視頻等信號，就必須採用衛星天線穩定跟蹤平臺系統。The ming dynasty used besides the technology of forefathers ' monsoon to make certain routes, the compass to gauide marching, they took a lot of records of the constellation oriented datas and the variety of the ocean orb ' s height in different oceanic areas in the book named < constellation chart of acrossing seas > too, which contribute a lot in the archaian astronomy
明朝船隊除了採用前人季風確定航線、指南針導航等技術外，還在《過洋牽星圖》中紀錄了眾多的星宿定位數據和不同海區天體高度的變化，對古代的天文導航有重要貢獻。Through the reaserch of the paper, a satellite transmission and television signal incepting system using stabilization platform which is used on the moving carrier ( vehicle, boat, ship etc ) has been designed. it uses an embedded system which is based on arm7tdmi core microcontroller and c / os - ii real - time operating system to control and scout the movement of the antenna stabilization platform, can realize the real - timable and reasonable stance control of the antenna, and then can realize the real - time communications and the signal receiving between the satellite and the moving carrier
3 .通過論文的研究，開發出了一種用於移動載體（車、船、艦等）上利用穩定平臺來進行衛星通信與電視信號接收的系統? ? 「動中通」移動載體衛星通信與電視接收系統。該系統採用基於arm7tdmi核微控制器和c / os - ii實時操作系統的嵌入式系統來控制天線穩定平臺的運動，可以實現對天線實時而合理的姿態控制，從而實現移動載體與衛星之間的實時通信和信號接收。A new method and the principle is presented for plotting the critical metacentric height curve which meets imo ' s intact stability criteria and weather criteria, and the critical metacentric height curve which meets 1976 solas intact stability criteria. and the critical metacentric height curve is used in the stability check of bulk grain carriers in accordance with the stability rules for bulk grain ca rriers
本文還具體給出了滿足imo完整穩性和天氣衡準的臨界初穩性高度的求作方法，以及滿足1976solas公約散裝穀物船舶的穩性衡準要求的臨界初穩性高度的原理和求作方法，並將由此得到的臨界初穩性高度曲線綜合運用到散裝穀物船舶的穩性校核。Then someone said something about the case of the s. s. lady cairns of swansea, run into by the mona, which was on an opposite tack, in rather muggyish weather and lost with all hands on deck
又有人提起，悶熱潮濕的一天，天鵝海港的「凱恩斯夫人」號輪船被同一航線上迎面駛來的「莫納」號撞沉，誰也不曾給他們任何援助，全體船員喪生。Lastly, establish the rigid - body spaceship attitude kinematics and dynamics equations, and primarily design the spaceship attitude law including limit loop parameters and two kind switch curves. analyze the astronaut ’ s disturbance moments. put the disturbance moments of typical astronaut ’ s push - off act as the input datas of the control system simulation, and analyze the response of the attitude control system after disturbed
最後，建立剛體飛船姿態運動學及動力學方程，並對飛船姿態控制律進行了初步的設計，包括極限環參數的設計和兩類典型的開關曲線的設計;對航天員擾動力矩進行了分析;以典型的航天員推離動作對飛船的擾動力矩作為控制系統模擬的輸入參數，分析姿態控制系統受到擾動后的響應。In addition, this paper succeeful design a ship - borne antenna stabilized system, introduce the hardware design and debug process
