GNSS Timing Module for 5G Network Synchronization

Trimble introduced its first dual-frequency — GPS L1 and L5 — embedded timing module providing next-generation wireless networks with 5-nanosecond accuracy. The Trimble RES 720 GNSS timing module is a surface-mount module that is easily integrated into network equipment. It uses L1 and L5 GNSS signals to provide superior protection to jamming and spoofing, mitigates multi-path in harsh environments, and adds security features for resilient networks.

The module measures 19 millimeters by 19 millimeters.

The RES 720 is designed for 5G Open RAN / XHaul, smart grid, data center, industrial automation and SATCOM networks as well as calibration services and perimeter monitoring applications. Trimble engineered the timing module to meet the resilient timing requirement mandated by the U.S. 2020 Executive Order (EO13095) for timing services and critical infrastructure operators. Using dual-frequency (L1 and L5), RES 720 provides better multi-path detection capabilities. Additionally, the dual-frequency capability provides protection against signal jamming and spoofing.

The multi-band capability also allows it to compensate for the ionospheric error from multi-GNSS satellite constellations, while reducing the timing error under clear skies to less than 5 nanoseconds. To further improve its accuracy locally, the RES 720 module features differential timing modes for highly accurate local timing.

Powered by Trimble’s Smart GNSS Assurance technology, the timing module offers protection against jamming and hacking of signals with automatic fallback to available GNSS signals. Infrastructure equipment suppliers, system integrators and network operators can benefit by integrating highly accurate synchronization capabilities into their network and synchrophasor devices, while enabling resilient timing for critical infrastructure.
