本文作的工作是利用信号仿真器仿真GPS数字中频信号，并借助这些仿真信 号完成对GPS信号的捕获和跟踪性能的研究。(This article is for the use of GPS signal simulator simulation digital IF signal, and make use of these simulation signal completion of the GPS signal acquisition and tracking performance study.)

航空航天通信技术一般采用模拟通信的频率调制和数字通信的移相键控调制方法。这有利于充分应用信道带宽和能源。频率调制是在一定程度上改变载波或副载波的频率来传输信息的调制方法。移相键控调制是利用载波或副载波的相位跳变来传输信息的调制方法。移相键控又分二相移相键控、四相移相键控和多相移相键控，其中以四相移相键控和八相移相键控调制方法的效率较高(Aerospace communications technology commonly used analog communication of frequency modulation and the digital communication phase shift keying modulation method. This is helpful for making full use of channel bandwidth and energy. Frequency modulation is changed to some extent carrier or subcarrier frequency to transmit information modulation method. Phase shift keying modulation is the use of carrier or subcarrier phase jump to transmit information modulation method. Phase shift keying and binary phase shift keying, four phase shift keying and multiple phase shift keying, of which four phase shift keying and eight phase shift keying modulation method of high efficiency )

在TOA测距的基础上，提出了一种三维无线传感器网络节点定位算法，并对其性能进行了分析，给出了算法的时间同步误差和定位误差。最后在现有仿真平台OMNET++的基础上构建三维仿真模块，对算法进行了仿真实现，给出了该算法的定位精度和覆盖率(This paper proposes one three-dimensional localization algorithm based on TOA distance measurement and analyzed the performance of the algorithm calculated time synchronization error and localization error. Finally it constructed three-dimensional simulation modules based on OMNET++ and implemented the algorithm educed the localization precision and coverage.)
