Furuno will release a high-performance multi-GNSS timing antenna, the AU-500, in July. The antenna is suitable for time synchronization applications.
The AU-500 supports all constellations in the L1 and L5 bands, including GPS, QZSS, GLONASS, Galileo, BeiDou, and NavIC. A built-in noise filter eliminates interference in the vicinity of 1.5 GHz caused by 4G/LTE mobile base stations as well as other radio waves that can adversely affect GNSS reception.
The antenna is equipped with lightening protection and features a high-quality polymer radome that prevents snow accumulation. It is also waterproof and dustproof in compliance with IP67.
The AU-500 achieves the best performance in time accuracy and robustness fundamental in critical infrastructure, when combined with Furuno’s GNSS receiver, GT-100.
In addition to the AU-500, Furuno will also launch the AU-300, an L1 single-band antenna with the same level of performance as AU-500, except L5 signal reception.
Furuno will participate in the Workshop on Synchronization and Timing Systems (WSTS) 2023, on March 13-16 in Vancouver, Canada.
The exhibition brings together the leading corporate and government experts to shed light on the diverse innovation taking place in the field of synchronization and timing.
Furuno’s Takahiko Ikeda, general manager of research and development, Systems Products Division, will speak on time synchronization in his presentation, “The Contribution on the Accuracy and Robustness of Time Synchronization in Multi-Constellation and Multi-Band GNSS Receivers.”
In this presentation, Ikeda will explain how L5 receivers are effective in time synchronization applications and how they contribute to the safe and secure operation of critical infrastructure, showing specific test results.
Furuno will also introduce and exhibit its latest GNSS receivers and antennas for timing. The featured products include:
• Timing multi-GNSS receiver module GT-100
• Multi-GNSS disciplined oscillator GF-8801/8802/8803 and GF-8804/8805
• Field time sync generator TB-1
• Dual-band GNSS antenna
Furuno Electric has announced a new global timing solution, GT-100, compatible with all GNSS constellations. The GT-100 realizes the world’s highest robustness and standard of time accuracy and stability. Interruption of GNSS satellite signals is a major concern for critical infrastructure systems. The GT-100 features advanced multipath mitigation, anti-jamming and anti-spoofing as well as short-term holdover, ensuring superior performance even if only L1 or only L5 are jammed.
The module delivers best-in-class nanosecond precision for 5G wireless systems, radio communications systems, smart power grids and grand master clocks.
Along with the GT-100, our GT-9001 and GT-90 achieve a level of time stability of 4.5ns (1σ) and offer superior features and performance.
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.
