| 摘 要： | Z跟踪技术是民用GPS接收机为消除或减弱AS（Anti—Spoofing）政策影响，实施精密测距和高精度导航定位的一种有效方法。通过分析Z跟踪技术载波相位测量的基本原理，研究了GPS接收机Z跟踪技术的抗压制干扰、抗欺骗干扰性能。结果表明：采用Z跟踪技术的GPS接收机与C／A码接收机的抗压制干扰基本相同；其在信号捕获状态下的抗欺骗干扰能力取决于欺骗干扰信号与GPS信号的相关程度，而在信号跟踪状态下抗欺骗干扰能力则等同于抗伪随机噪声码干扰能力。

| Abstract: | Z-Tracking technique is an effective technique for civilian GPS receivers to eliminate or weaken the impact of AS(Anti-Spoofing) policy, and to implement precision ranging, navigation & positioning. By analyzing the principles of measuring the carrier phases by Z-Tracking technique, the performances of anti-jamming and anti-spoof of Z-Tracking technique are discussed in this paper. The result shows that the GPS receivers which adopt Z-Tracking technique have the almost same anti-jamming performance as C/A c... |
