GT-88

Timing Multi-GNSS Receiver Module

More details

  • Concurrent reception of GPS/GLONASS/Galileo/QZSS/SBAS
  • 1PPS stability : <4.5nsec (1sigma)
  • TRAIM, Single Satellite Tracking, Multipath Mitigation, Anti-Jamming and Anti-Spoofing
  • Configurable frequency output (10Hz to 40MHz)

Extremely high stability of 4.5ns (1sigma) using a single band receiver

The GT-88 is the high-stability, high-accuracy timing Multi-GNSS receiver.
It incorporates Dynamic Satellite Selection™, which is a new satellite signal selection algorithm developed by NTT. Thanks to that GT-88 permits GNSS antennas to be mounted more freely than ever before including wall mounting and window mounting installations.

Features

Enable to output accurate and robust UTC time and 1PPS synchronized with UTC time

FURUNO technology made it possible to achieve 5G-required performance. 4.5ns (1 sigma) by a single band receiver is obtained. This is achieved by an improved and advanced position estimation algorithm. It optimizes position calculations using several different GNSS satellite constellations. It allows users to achieve 5G-required performance without changing existing single band GNSS antennas.


GNSS antennas can be mounted on walls and windows of tall buildings

The Dynamic Satellite Selection™* minimizes deterioration of time synchronization performance by choosing only the high quality satellite signal* a new satellite signal selection algorithm developed by NTT

Suitable for various RF・Broadcasting applications. Designed functions aiming to solve usual troubles on site.

The number of radio stations applied with GNSS time synchronization, ex. PMR, local 5G, and V2X, has been increasing year by year. Especially in urban area, users have to face problems such as urban canyon (signals blocked) and multi-path (signals reflected) etc.

  1. Multipath in Urban area
  2. Jamming (interference wave)
  3. Spoofing
