  2. Metropolitan circle is the result of industrialization and urbanization, which is the embodiment of centralization and radialization when the metropolis is developing to a certainty, in order to advance the space and economy to conform, to form a corporate area, fabricating the new type of metropolitan circle in which the metropolis is the core is new topic for discussion of innovative space structure of the big ciry this paper combine the theory expatiation and demonstration analysis with comprehensive and new statistics data, and theory model, and discusses the all - around regional development in chengdu area from a new angle, ie : using space structure model of metropolitan circle to develop the overall enhancement of strength in chengdu first, the thesis defmitudes the concept, connotation, and character of metropolitan circle, after that, it discusses the formative mechanism of metropolitan circle from the factors such as market, institution and ect moreover, from the practice of metropolitan circle ' s development in ho me and abroad, it summarizes the significance of the metropolitan circle form for the economic and social development, as well as the experience for reference and the problems we should pay attention to = based on these theories and practice, it brings forward the necessity and strategic significance of building metropolitan circle in chengdu, and analysis its possibilities, it also makes a research on the model of this circle, it innovatively brings forth that the double - polar circle structure of central city - sub central city - satellite town should be builded, through the establishment of index system, the sphere of metropolis circle in chengdu can be set which means the central city, sub center city and satellite town are sett it also analysis how to determine the gravity between center city and circumjacent area, and discusses the function orientation of center city and satellite town at last, it briefly analyses the transportation designing of suburb and city which are imperative for constructing the metropolitan circle in chengdu

    本文將理論闡述和經驗實證分析與較全面的最新統計資料,以及理論分析模型分析結合起來,從新的角度深入探討成都的區域整體發展,即以都市圈的空間結構模式促進成都整體實力的全面提高。本論文首先明確了都市圈的概念、內涵及特徵,從市場、等因素探討了都市圈的形成機理,並從國內外都市圈的發展實踐中,總結出都市圈這種空間形式所引起的經濟和社會發展的意義所在,以及我們值得借鑒的經驗和需要注意的問題。在此理論和實踐基礎上,提出構建成都都市圈的必要性及戰略意義,分析其可能性;並且對如何構建成都都市圈模式進行了探討,主要是創新性提出構建中心城市-副中心城市-衛星城鎮的雙極圈域結構,並通過指標體系的建立以確定成都都市圈的范圍,即中心城市、副中心城市和衛星城鎮的確定,以及測定中心城市與周邊地區的引力大小,以及對中心城市和衛星城鎮的功能定位進行了探討。
  3. Its main contributions include the following several aspects : firstly, the dissertation constructs the mathematic model of short baseline orientation determination using two geostationary satellites and analyses the applicable conditions of carrier phase interferometry. orientation determination precision is analysed in depth through both the conventional linearized method and monte - carlo computer simulation method, and the mathematical simulation results show that the linearized method has the shortcoming of fairly low elevation error analysis precision in high latitude area so as not to be very appropriate there. by analyzing the definite factors influencing orientation precision, the dissertation develops the concept of orientation dilution of precision, which uncovers the internal cause of exotic error behavior of bi - satellite orientation, and has important guiding significance for practical engineering applications

    本文系統地研究了基於「北斗一號」衛星載波相位干涉測量原理實現地球靜止雙星定向的相關技術,主要研究成果包括以下幾方面:首先,建立了利用兩顆地球靜止軌道衛星進行短基線定向的數學模型,分析了載波相位干涉測量的適用條件;採用傳統的線性化解析法及蒙特卡洛隨機模擬法兩種途徑對雙星定向的精度進行了詳細分析,數學模擬結果表明在高緯度地區線性化解析法由於俯仰角誤差分析精度略有下降而不太適合;在分析定向精度確定性影響因素的基礎上,提出了雙星定向精度衰減因子odop的概念,揭示了雙星定向誤差特殊表現的內部機理,對實際工程應用具有重要的指導意義。
  4. This dissertation introduces a kind of car navigation system which use inertial navigation equipments and gps navigation satellite to realize the real time orientation. this instrument for navigation can measure informations of vehicle instantaneously, such as altitude, longitude, latitude and display these information on tft lcd

    本文介紹了一種利用車載慣性導航設備和gps導航衛星進行車輛實時定位的導航系統,該導航儀用於實時測量車輛的經緯度、高度等數據信息,並顯示在外掛的tft液晶屏上。
  5. In the management of city transportation, navigation of satellite cannot meet the practical requirement because of shielding and interfering of satellite signal. therefore, map matching and dead - reckoning ( dr ) is used to assistant navigation. this combination is defined as gps / dr integrated navigation system, in which the map matching is used for correcting the orientation and distance errors of dr

    而在城市交通管理的應用中,由於衛星定位信號經常會受到建築物的遮擋和干擾,衛星定位無法滿足導航的實際要求,通常需用地圖匹配和航位推算器( dead - reckoning , dr )的方法進行輔助導航,這種導航方式稱為組合導航系統,其中地圖匹配可用來修正dr的方向和距離的系統誤差,以便在衛星信號失鎖時,提高dr自主定位的精度。
