GNSS L1 reception for timing and synchronization in outdoor infrastructures

GPS-PR1 is a Global Navigation Satellite System (GNSS) antenna designed to receive the L1 navigation signals transmitted by GPS, GLONASS and Galileo. In professional telecom environments, GNSS timing is a key reference for synchronization devices used across digital networks, including 4G and 5G infrastructures, where accurate timing helps maintain network stability and coordination.

Outdoor robustness for extreme weather and exposed sites

The antenna construction is engineered to be perfectly waterproof and suitable for extreme weather conditions. The radome fully covers the antenna and is shaped to reduce snow accumulation while protecting internal parts, the support pole interface and the power connector area. This makes GPS-PR1 a practical choice for exposed rooftops, towers and infrastructure sites where long-term reliability matters.

Designed for high RF field environments and end-of-line locations

GPS-PR1 is specifically intended for operation in places with strong radiofrequency fields such as radio-television stations or telephone radio-base stations, supporting synchronization equipment for digital networks. For infrastructure layouts where the GNSS reference is required outside a tunnel system (for example at portal or end-of-line “end-over” sites), the outdoor design and quick fixing concept help simplify deployment and maintenance.

The fixing system allows fast and simple locking for both vertical and horizontal mounting configurations, supporting installation flexibility on standard masts.
