Superior Accuracy / Advanced Robustness
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, smart power grids and more, where there are ever-increasing needs for high robustness, reliability and security.

Three new products being released include GT-100, GT-9001 and GT-90, designed to suit different applications based on frequency bands and output signals supported. All models boast the world's highest level of time stability of 4.5ns (1 sigma) and offer superior features and performance.

-Unrivaled performance for 5G, radio communications, time servers, smart grids
-Dual band, supporting all constellations (GT-100)
-Highly precise time & ultra-low-jitter 1pps synchronized with UTC
-High robustness -- guaranteed performance even if only L1 or only L5 signals are used (GT-100)
-Programmable frequency clock outputs synchronized with UTC (GT-9001 & GT-100)
-Excellent performance even in harsh environments and urban canyons

All models are equipped with the leading Dynamic Satellite Selection (TM) (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.

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. GT-100 delivers three outputs including 1 pulse per second (1PPS) synchronized with UTC as well as user-programmable frequencies. The outputs can be set as required to 10MHz, 2.048 MHz, 19.2 MHz, etc., 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.

FURUNO to Launch Single-band GNSS Receivers That Achieve 4.5ns Stability
- GT-88: GNSS Timing Module; GF-8801/02/03/04/05: GNSS Disciplined Oscillator -

Furuno Electric Co., Ltd. (FURUNO), based in Nishinomiya, Japan, has developed GT-88 and GF-8801/02/03/04/05 for users who require UTC time-synchronized signals to meet the new 5G requirements. They provide UTC time-synchronized timing signals (1PPS/10MHz) by receiving GNSS satellite signals. Achieved stability is better than that of an atomic clock, including a rubidium. The GT/GF-88 series includes a brand-new algorithm, named Dynamic Satellite Selection (trademark) that provides outstanding multipath mitigation, especially in urban canyon environments. This algorithm was developed by Nippon Telegraph and Telephone Corporation (NTT) based in Tokyo, Japan.

- Extremely high stability of 4.5ns (1 sigma) is obtained, only requiring reception of the L1 band (1575.42 MHz) frequency GNSS satellites. It was achieved by improving advanced position estimation algorithms and optimizing position calculation among several different GNSS satellite constellations. It allows users to achieve 5G-required performance without any changes to existing single-band GNSS antennas.

- It incorporates the Dynamic Satellite Selection (trademark), an advanced multipath mitigation algorithm developed by NTT. Normally typical time synchronization performance deteriorates in urban canyon environments by the effect of multipath. The Dynamic Satellite Selection (trademark) reduces this time error by one-fifth. This provides more flexibility when installing GNSS antennas. Consequently, the GT/GF-88 series now permits GNSS antennas to be mounted on walls, windows of tall buildings and other difficult reception environments.

- The GT/GF-88 series continues to support GPS, GLONASS and QZSS satellite constellations, and now adds Galileo support. As the total number of satellites available increases, operational stability also increases.

シングルバンドで時刻精度4.5ナノ秒(1σ)のGNSSレシーバを開発
GNSSタイミングモジュール「型式：GT-88」、GNSS基準周波数発生器「型式：GF-88シリーズ」
古野電気株式会社（本社：兵庫県西宮市、代表取締役社長：古野幸男　以下、当社）はこのたび、第5世代移動通信システム（5G）や次世代送電網（スマートグリッド）などで高精度な時刻同期（UTC同期）を必要とするユーザーに向けて、GNSSタイミングモジュール「型式：GT-88」と、GNSS基準周波数発生器「型式：GF-88シリーズ」を開発しました。

本商品はGNSS衛星からの信号を受信するだけで、手軽に原子時計に匹敵するタイミング信号を、弊社従来製品と比較して3倍以上の高精度で取得できるGNSSレシーバです。また、日本電信電話株式会社（本社：東京都千代田区、代表取締役社長：澤田純　以下、ＮＴＴ）が考案したまったく新しいマルチパス（反射波）対策アルゴリズムである「ダイナミック・サテライト・セレクション™」も搭載しています(2018年10月に公表済み)。今後は、市街地などで高精度な時刻同期を必要とする5Gスモールセル、V2X、グランドマスタークロック（注1）を中心に、幅広く展開する予定です。

◆本商品は、GNSS衛星から送信されているL1帯（1575.42MHz）の信号の受信のみで時刻同期精度4.5ナノ秒（1σ）(注2)を達成する時刻同期用シングルバンドGNSSレシーバです。同等の時刻同期精度を持つGNSSレシーバは既に市場に存在しますが、それらはL1帯の他に、L2帯（1227.60MHz）やL5帯（1176.45MHz）などの複数の周波数帯に跨る信号の受信が必要なマルチバンドGNSSレシーバでした。当社は位置推定アルゴリズムの改良や、各国の衛星間の測位演算の最適化等により、マルチバンドGNSSレシーバよりもシンプルなシングルバンドGNSSレシーバで同等以上の時刻同期性能を実現します。これによりユーザーは、市場に広く流通する一般的なGNSSアンテナのままで、4.5ナノ秒（1σ）という高精度な時刻同期を実現できるようになります。
◆本商品は、ＮＴＴが考案したマルチパス対策アルゴリズム「ダイナミック・サテライト・セレクション™」を搭載しています。一般的にビル街のようなアーバンキャニオン環境においては、マルチパスによって時刻同期の精度が劣化します。「ダイナミック・サテライト・セレクション™」は時刻誤差の原因となるマルチパス信号を大胆に「枝刈り」することにより、時刻誤差を従来の1/5程度にまで低減しました。これにより、GNSSアンテナの設置の自由度が向上します。市街地はもちろん、今までは遮蔽などの条件が厳しすぎて設置が難しかったビルの壁面や、屋内の窓際などでもアンテナを設置できるようになります。
◆GNSS衛星に関しては、従来のGPS・GLONASS・QZSS(みちびき)に加え、新たに欧州のGalileoにも対応しました。またQZSSに関しては、 L1 C/A信号の4機同時受信と、L1S信号にも対応しています。トータルで利用できる衛星数が増加したため、見晴らしのあまり良くない受信環境でも、より多くの衛星を受信できるようになりました。「ダイナミック・サテライト・セレクション™」の適用効果も一層向上し、より高精度な時刻同期を実現することができます。
◆当社は今後も、通信や放送、電力などの、高精度・高信頼性が求められる分野で、施設運用者が安心して時刻同期を利用できるよう、技術開発を進めてゆく方針です。なお、本商品の仕様等の詳細は、下記の製品情報サイトにてご確認頂けます。

FURUNO Launches World's Smallest and Lightest Weather Radar System for Meteorological Monitoring

FURUNO — Wed, 28 Aug 2013 13:01:47 +0900

NISHINOMIYA, Japan, Aug. 28 /Kyodo JBN/ --
FURUNO ELECTRIC CO., LTD.
FURUNO Launches World's Smallest and Lightest Weather Radar System for Meteorological Monitoring and Analysis
FURUNO ELECTRIC CO., LTD. is pleased to announce that the development process of FURUNO X-band Doppler Weather Radar (Note 1) has been completed. Subsequently, FURUNO is looking to deliver a solution for meteorological analysis that would greatly contribute to better safety in society where the impact arising from meteorological disasters can be diminished.
(Note 1) Doppler Weather Radar measures not only the location and intensity of precipitation but also the wind speed and direction around radar sensors by analyzing the Doppler shift of radio waves returned from precipitation particles in the wind.

FURUNO's new Weather Radar system consists of the Dual Polarimetric X-band Doppler Weather Radar (Note 2) WR-2100 and the X-band Doppler Weather Radar (Note 3) WR-50 that can be classified as one of the world's smallest and lightest systems available in the market. It is best suited for local weather monitoring and forecasting, facilitating high-precision real-time 3D monitoring of meteorological phenomena.
(Note 2) Dual Polarimetric Doppler Weather Radar simultaneously transmits horizontally and vertically polarized radio waves, and analyzes the difference in received signal returns and their phase difference to compute quantitatively analyzed precipitation.
(Note 3) Doppler Weather Radar, in general, transmits horizontally polarized radio waves and calculates precipitation intensity from signal returns.

The WR-2100 has ultra high-definition spatiotemporal resolution capability (Note 4), capable of grasping omni-directional precipitation intensity in a 50-meter mesh at 6-second intervals. Also, the WR-2100 is capable of conducting a high-precision scan to obtain the vertical structure of a cumulonimbus, which causes precipitation, as well as monitoring the movement of the nimbus and the formulation of raindrops.
(Note 4) Ultra high-definition spatiotemporal resolution capability is the ability to monitor and analyze localized phenomena minutely within the short duration of time.

Conventional weather radar , which is generally enormous and deployed at the top of mountains, is not suited for locating nimbus emerged at an altitude from 500 to 2,000 m. It is such nimbus that the FURUNO Weather Radar system is intended for locating. Its radar antennas are designed to be deployed at the rooftop deck of buildings in urban areas in mesh configuration with a distance of 30 km between each antenna. As a result, the radar system can detect nimbus in the distance, even though it may be blocked by other nimbus at a closer range. At the moment, FURUNO is looking to utilize this new radar technology to enhance the precision level of rainfall prediction and to detect the development of short localized rainstorms, which are hard to predict.

A "multi radar system" is constructed by networking more than three WR-2100s. Alternatively, the system can also be constructed by networking one WR-2100 together with two WR-50s, the latter of which conducts real-time monitoring of the horizontal movement of nimbus. It is capable of detecting short localized rainstorms, which have often occurred recently in urban areas in Japan, and conducting 3D-monitoring of rainstorms in real time. Also, joint efforts between industry and academia (Note 5) are being made to realize practical application of localized weather forecasting systems.
(Note 5) FURUNO conducts research and development for technology to facilitate real-time rainfall prediction by means of ultra high-definition spatiotemporal resolution analysis, in close collaboration with Kobe University, Kyoto University and Japan Science and Technology Agency as part of the "Adaptive and Seamless Technology Transfer Program through Target-driven R&D" of Japan's Science and Technology Agency.

The new weather radar's radome diameters are greatly downsized (to 108 cm for WR-2100 and 60 cm for WR-50) compared with the conventional X-band weather radar whose radome diameter is approximately 3.5 m. Needless to say, it is drastic downsizing from the conventional C-band and S-band weather radar whose radome diameters are 7.0 m and 12.0 m, respectively.

The antenna unit of the WR-2100 or the WR-50 can be tucked in a minivan to be carried to a monitoring location. Also, it can be carried through an elevator to bring them up onto a monitoring site and installed by human labor without using heavy machinery such as cranes. What is more, the use of commercial electricity for its operation widens the scope of potential clients, who have hitherto shied away from employing the conventional weather radar system because of its limitations on available installation sites as well as operational costs. Such clients include weather service providers, local governments and research institutes as well as other business organizations that provide information and conduct operation management for facilities of public transportation, sewage works, river authorities, civil engineering, agriculture, tourism, etc.

The new weather radar system is going to be exhibited at METEOROLOGICAL TECHNOLOGY WORLD EXPO 2013 to be held in this coming October in Brussels, Belgium.

Please visit the website http://www.furuno.com/en/systems/ to find out more about detailed specifications of the weather radar system as well as the case studies of meteorological monitoring conducted.

New Multi-GNSS Receiver Chips "eRideOPUS 6" and "eRideOPUS 7" to Be Available from Summer 2013

FURUNO — Thu, 28 Mar 2013 13:00:23 +0900

Nishinomiya, JAPAN, Mar. 28 /Kyodo JBN/ --
FURUNO ELECTRIC CO., LTD.
New Multi-GNSS Receiver Chips "eRideOPUS 6" and "eRideOPUS 7" to Be Available from Summer 2013
FURUNO ELECTRIC CO., LTD. announced on March 28 that new multi-GNSS receiver chips eRideOPUS 6 and eRideOPUS 7 will be available to the market from August 2013 onward. The new receiver chips are multi-GNSS compliant single-chip LSIs, capable of concurrently receiving signals from multiple satellites in GNSS systems, i.e., GPS, GLONASS*, Galileo, etc., and satellite-based augmentation systems as well as Japan's Quasi-Zenith Satellite System.
* eRideOPUS 7 only

The ability of concurrently receiving GNSS/GNSS augmentation signals from multiple satellites from different satellite services means that the receivers have more probability of acquiring a greater number of satellites at any single point of time. Subsequently, position stability as well as accuracy will be greatly improved, minimizing the chance of a position lost. Also, the receiver chips incorporate an enhanced level of noise rejection capability, implementing the anti-jamming function as well as the improvement of multi-path mitigation.

Time-to-first-fix capability of the existing eRideOPUS 5 (no more than 1 second when hot started) is retained in these new receiver chips with a combination of A-GPS compatibility and self-ephemeris (TM) extraction. Moreover, the position update rate of the new receiver chips is greatly improved, achieving a 10 Hz update (every 0.1 second), which is twice as fast as the capability achieved by eRideOPUS 5.

The new receiver chips are capable of dead reckoning navigation, using a gyro sensor and vehicle speed pulse signals, a gyro sensor and an acceleration sensor, and wheel tick data taken from a CAN-Bus network, achieving high positioning accuracy even in locations where satellite signal reception is not available, such as inside tunnels.

In May 2013, FURUNO is planning to start the delivery of evaluation kits for the receiver chips so that third-party manufacturers can evaluate the feasibility of incorporating the receiver chips into their products, and in August 2013, the new compact GNSS receiver module GN-86/GN-87 as well as dead-reckoning-capable GV-86/GV-87, using these new receiver chips, will be made available for automotive navigation systems as well as eCall systems.
