摘要自从1973年美国GPS全球定位系统投入使用以来，GPS全球定位系统不仅在卫星导航领域占有重要地位，而且在地质勘探、交通运输、航天航空、国防军事等领域同样也发挥着重要的作用。在科技不断发展的现在，GPS正向着高精度、高动态、高灵敏度以及高抗干扰性发展。GPS接收机是GPS中一个关键的组成部分。在高动态环境下，接收机需要进一步的改善。
文章首先介绍了GPS全球定位系统的原理。包括系统组成，GPS卫星信号构成以及GPS定位原理。然后介绍高动态环境对卫星信号的影响，分析了GPS卫星信号的快速捕获跟踪的原理和方法。接着提出立方体小型化高动态GPS接收机的设计方案，在Altium Designer的环境下完成GPS接收机的原理图设计。最后，演示GPS信号接收机工作的流程。22619

Title High dynamic miniaturization of cube satellite GPS receiver Solutions Design
Abstract
Since 1973 when the U.S. GPS global positioning system put into use, GPS global positioning system not only plays an important role in the field of satellite navigation,but also play an important role in geological exploration,transportation, aerospace, defense, military and other fields also . In the evolving technology now,GPS is heading high precision,high dynamic, high sensitivity and high noise immunity development.GPS receiver is a key component. In high dynamic environment, the receiver needs to be further improved.
The article first introduces the principle of GPS global positioning system.Including system components,constitution of GPS satellite signal and GPS positioning principle .Then describes the impact of high dynamic environment on satellite signals,analyzes the principle and the method is fast capturing GPS satellite signals to track. Then puts forward the design of miniaturized cube of high dynamic GPS receiver ,complete the schematic design of the GPS receiver in the Altium Designer environment. Finally,demonstrates the work processes of GPS signal receiver .
Keywords GPS receiver highly dynamic miniaturization
