In an era of rising threats to GNSS—from jamming and spoofing to complex RF interference—Controlled Reception Pattern Antennas (CRPAs) have become essential tools in the pursuit of resilient PNT (Positioning, Navigation and Timing). Utilizing multiple antenna elements in concert, CRPAs and other array antennas are able to determine angle of arrival to focus antenna gain towards genuine satellite signals and steer nulls towards sources of interference, reducing the effectiveness of these increasingly-common attack vectors. This on-demand webinar brings together international experts from Spirent, the German Aerospace Center (DLR), Hexagon, and Thales Alenia Space to explore how CRPA technology is evolving—and how it's being tested, simulated, and deployed to meet today’s toughest challenges in GNSS resilience.

今天，抗干扰和抗欺骗能力已成为关键任务GNSS接收机和系统的必备条件，受控辐射模式天线（CRPA）和其它自适应天线系统的测试也成为其中的关键环节。无论是来自民用来源，还是国家部署的电子战方法，信号干扰和欺骗的威胁都在与日俱增。自适应天线是最初是一种为军事用途开发的技术，而现在已被越来越广泛地用于勘测、采矿和自动驾驶车辆等商业应用。

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.

全球导航卫星系统（GNSS）的使用已经普及各行各业，但也面临着日益严重的GNSS干扰和欺骗威胁。为保护商业航空、航运和自动驾驶车辆等关键应用，德国航空航天中心认为开发抗干扰和抗欺骗技术已经成为当务之急。DLR已经开发出了GALANT － 一种使用归零和波束塑型来对抗干扰的先进系统。

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.
