PNT X模拟系统

Navigation warfare, or NAVWAR for short, is a subset of electronic warfare that refers to attempts to disrupt the navigation capabilities of enemy forces. Primarily consisting of jamming and spoofing attacks, NAVWAR has become a key battleground in recent years. Equally as importantly, its proliferation is having a significant impact on commercial and civilian operations around the world. In this eBook, Spirent looks at some of the key considerations for enhancing NAVWAR robustness and winning in the NAVWAR space. This includes the technologies and techniques available, but primarily looks at the requirements and provisions for the key development space: the test lab.

选择适合您的GNSS模拟器 公认的事实是，在对具备GNSS能力的设备进行测试时，模拟已成为首要的工具。然而，要想选择正确的模拟器并非易事。首先要关注的是特性列表 － 该模拟器是否能够提供您需要的功能？之后，您还需要确定该模拟器的性能是否能达到您的预期。如果性能不济，它可能给您的产品，甚至您的整个业务，带来灾难性的后果。

Modern vehicles, whether autonomous or assisted, heavily rely on precise positioning, navigation, and timing (PNT) information for safety, efficiency, and mission-critical tasks. GNSS technology has evolved to meet these demands, offering a variety of hardware and services options, including multi-constellation and multi-frequency receivers, terrestrial and space-based augmentation systems, and complex array antennas. However, the inclusion of additional PNT sensors working together with GNSS has become increasingly important for seamless and reliable performance.

The reliance on GNSS signals for positioning, navigation, and timing (PNT) has made radio frequency (RF) interference from signal jamming a growing threat across various industries. Whether intentional or unintentional, jamming can significantly impact the performance of GNSS receivers, including those used for safety-critical and liability-critical operations. Therefore, developers and integrators of GNSS receivers must understand the risks presented by jamming and implement mitigation measures to protect the receivers and their users.

干扰和欺骗已成为现代导航战（NAVWAR）中的关键组成部分，针对它们的测试也变得越来越关键，而对测试中更高真实性的需求也在急速攀升。无论是传统的军事应用、现代无人机作战，还是航空等民用领域，都感受到了干扰和欺骗所带来的影响，因此，搭建更强健的且更具弹性的系统可能不仅决定成败，甚至可能决定生死。 在此次网络研讨会中，思博伦的专家小组将讨论最新的研究，演示GNSS干扰对机载接收机的不同影响。该测试不仅考虑到了被测载具的动态，也考虑了干扰信标的动态，并且融入了信号与本地环境互动所导致的各类真实效应。
