Design And Implementation Of B1/L1 High Dynamic Navigation Receiving Terminal

In this era of rapid development of science and technology,the application demand of satellite navigation is very huge.In recent years,the demand of special environment has soaring,such as high dynamic environment,and its role in strategic missiles is self-evident.Now,the strong development of China's Beidou navigation satellite system has promoted the progress of localized high dynamic navigation receiving terminal.Therefore,the research and development of a receiving terminal capable of position and navigation in a high dynamic environment is the focus of this project.Among them,the construction of hardware platform of navigation and receiving terminal is the premise,navigation and positioning algorithms are the basis,and these algorithms directly affect the performance index of high dynamic navigation and receiving terminal.In this paper,the hardware platform and the software algorithm are designed by B1/L1 high-dynamic navigation receiving terminal are studied and improved in detail.The specific contents are as follows:1)For the theoretical verification before the realization of the high dynamic navigation receiving terminal,the paper analyzes the basic positioning principle of the satellite navigation receiving terminal;then the whole high dynamic navigation receiving terminal is simulated by MATLAB,including the separate simulation verification of the key algorithms such as fast acquisition,high dynamic tracking algorithm and PVT solution,initially has a preliminary evaluation on the algorithm performance of the whole navigation solution;In addition,the software platform environment of hardware design and software program development joint debugging is introduced in detail.2)After the completion of theoretical verification and simulation,the overall architecture of satellite navigation receiving terminal,including the main functional parts such as RF and A / D conversion,baseband signal processing,as well as the key parts such as hardware circuit,acquisition and tracking in high dynamic environment,is realized and analyzed through Vivado and other tools.3)Test and simulate the internal simulation source,external signal source and the whole hardware of the navigation receiving terminal,and verify whether the design of the high dynamic navigation receiving terminal meets the normal requirements through the test of various aspects.
