Furuno Electric Co. has released a new generation of time-synchronization GNSS receiver modules compatible with all GNSS systems. The modules deliver nanosecond precision for 5G mobile systems, radio communications systems, smart power grids and grand master clocks.

GNSS receivers for time synchronization are used extensively in critical infrastructure such as mobile base stations and RAN equipment, commercial and defense radio communications, broadcasting, financial trading and smart power grids, where there are increasing needs for robustness, reliability and security.

Furuno is releasing three new products: GT-100, GT-9001 and GT-90. They are designed to suit different applications based on the frequency bands and output signals supported. All models have the world’s highest level of time stability of 4.5 ns (1 sigma).

The GT-100 is the company’s first timing multi-GNSS receiver module supporting concurrent L1 and L5 reception. This mitigates the effects of solar flares, which can lead to time errors, and strengthens measures against GNSS vulnerabilities such as jamming and spoofing.

  • The GT-100 delivers three outputs including 1 pulse per second (1 PPS) synchronized with UTC as well as user-programmable frequencies. The outputs can be set as required to 10 MHz, 2.048 MHz and 19.2 MHz, commonly used in a variety of wireless communications systems. This drastically reduces the time from development to market launch for these systems, as well as cost savings through reduced component needs. GT-100 is a full-featured highly robust model, supporting dual-frequency band reception (L1 and L5).
  • GT-9001 supports L1 and delivers high stability 1PPS and programmable clocks on three channels.
  • GT-90 supports L1 and provides a 1 PPS high stability output.

All models are equipped with the leading Dynamic Satellite Selection (DSS) multipath mitigation technology developed by Nippon Telegraph and Telephone Corporation (NTT) that minimizes degradation of time performance even when the antenna is installed in urban areas or near a window.

Furuno will showcase the new modules at EuMW’s European Microwave Exhibition, a trade and technology exhibition providing access to initiatives in the RF and microwave sector.

Evaluation kits for all three products are available now.
