随着新卫星信号频段的不断扩大,卫星定位、导航与授时 (PNT) 技术的发展也取得了显著进步,极大等。最初,GPS 等 GNSS 系统主要在 L1 频率上运行,由单频段接收机使用。
随着时间的推移,这种技术已经发展到包括双频段和多频段接收机,可以访问额外的 L2 和/或 L5 频率。这些改进大大提高了所提供服务的准确性、可靠性和安全性。
全频段 GNSS 包含所有工作频段,L1、L2 和 L5,同时还增加了对新的 L6/E6 频段的支持。通过这种全面的频谱覆盖范围,GNSS 接收机可充分利用各种卫星信号和服务。凭借这一前沿技术,接收机可确保为汽车级 ,汽车、工业和授时领域的复杂应用提供最佳精度和可靠性。
多种频率的集成提高了定位精度,可实现以下功能:
凭借这些功能,全波段 GNSS 接收器可满足广泛的用户需求。它们可以提供更高的性能,在越来越依赖精确可靠的定位技术的世界中实现新的应用。
u-blox X20 全频段平台使 GNSS 接收机能够同时接收所有 GNSS
L 频段信号,为高精度定位解决方案带来诸多优势。

Find out how the ZED-X20P GNSS receiver and PointPerfect portfolio work together to provide worldwide
high-precision positioning.
An all-band GNSS receiver supports all available satellite constellations and frequencies, as well as multiple frequency bands like L1, L2, L5, L6, and L-band. By receiving signals from all these sources simultaneously, it enhances positioning accuracy and reliability, even in challenging environments. This multi-frequency capability helps reduce signal obstructions and minimize errors caused by multipath effects, making it ideal for applications where precision is critical - such as surveying, autonomous vehicles, and industrial automation.
The all-global capability ensures accurate positioning anywhere in the world, enabling seamless global deployment. Thanks to advanced correction technologies like RTK, PPP-RTK, and PPP. With support for services like PointPerfect Global, these receivers provide centimeter-level accuracy on a global scale. Whether in remote locations or dense urban environments, all-global receivers deliver consistent, real-time positioning data, making them essential for precision agriculture, maritime navigation, and smart infrastructure development.
By combining all-band and all-global capabilities, GNSS receivers offer a robust, high-accuracy solution for demanding applications where reliability and precision matter most.
