【摘要】：北斗衛(wèi)星導(dǎo)航定位系統(tǒng)是我國自主研發(fā)的衛(wèi)星導(dǎo)航定位系統(tǒng)，具有完全的獨立自主性，最終目標是提供全球范圍內(nèi)的定位服務(wù)，由于定位導(dǎo)航系統(tǒng)在社會各個領(lǐng)域的作用愈顯明顯，北斗衛(wèi)星導(dǎo)航定位系統(tǒng)的研究愈發(fā)重要。 本文首先介紹了北斗衛(wèi)星導(dǎo)航定位系統(tǒng)的基本原理，包括跟北斗信號通信相關(guān)的通信知識，還有北斗衛(wèi)星導(dǎo)航定位系統(tǒng)的定位原理。然后，介紹了一種北斗衛(wèi)星接收機的實現(xiàn)辦法，簡要介紹了其硬件結(jié)構(gòu)后，詳細介紹了其軟件系統(tǒng)的設(shè)計，包括系統(tǒng)的選擇和部分界面的設(shè)計。 隨后，我們分析了造成北斗系統(tǒng)定位誤差的因素，針對每一個因素，介紹了提高定位精度的措施。最后，主要對北斗接收機定位解算算法進行了簡要的分析，首先是利用最小二乘迭代法進行定位解算，為了提高解算效率，又研究了卡爾曼濾波法進行定位解算，但是以上兩種方式是線性系統(tǒng)的處理方法，，由于北斗的定位解算模型是非線性的，我們又研究了擴展卡爾曼濾波法和無跡卡爾曼濾波法，兩種算法的定位精度和計算速度均優(yōu)于以上兩種算法。
[Abstract]:Beidou Satellite Navigation and Positioning system is a independently developed satellite navigation and positioning system in China. It is completely independent and autonomous. The ultimate goal is to provide positioning services on a global scale.The research of Beidou satellite navigation and positioning system becomes more and more important because the role of positioning and navigation system is more and more obvious in various fields of society.This paper first introduces the basic principles of Beidou satellite navigation and positioning system, including the communication knowledge related to Beidou signal communication, and the positioning principle of Beidou satellite navigation and positioning system.Then, this paper introduces a method to realize the Beidou satellite receiver, briefly introduces its hardware structure, and then introduces the design of its software system in detail, including the selection of the system and the design of some interfaces.Then, we analyze the factors that cause the positioning error of Beidou system, and introduce the measures to improve the positioning accuracy for each factor.Finally, a brief analysis of the Beidou receiver positioning solution method is given. Firstly, the least square iterative method is used to solve the problem. In order to improve the efficiency of the algorithm, the Kalman filter method is also studied.However, the above two methods are the processing methods of linear systems. Since the Beidou location solution model is nonlinear, we also study the extended Kalman filtering method and the unscented Kalman filter method.The positioning accuracy and computing speed of the two algorithms are better than those of the above two algorithms.
