Trimble has introduced its first dual-frequency embedded timing module that provides next-generation networks with 5-nanosecond accuracy.
Surface mountable, the Trimble RES 720 GNSS timing module can be integrated into network equipment. It uses L1 and L5 GNSS signals to provide superior protection to jamming and spoofing, mitigates multipath in harsh environments, and adds security features to make it suitable for resilient networks.
Precise timing and synchronization optimizes and improves wireless network performance. At 19 x 19 millimeters, the RES 720 module provides a low-cost, easy-to-use, highly accurate and reliable GPS timing source for critical infrastructure in a broad range of industries. The RES 720 is suitable for 5G Open RAN/XHaul, smart grids, data centers, industrial automation and satellite communication networks, as well as calibration services and perimeter monitoring applications.
The RES 720 meets 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 multipath detection capabilities than single frequency, and provides protection against signal jamming and spoofing. Multi-band capability helps 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 RES 720 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 synchro-phasor devices, while enabling resilient timing for critical infrastructure.
The RES 720 is expected to be available in the second quarter of 2021.
