GNSS for Time Sync

Timing GPS Receiver Module

Model GT-86

Old Products

High sensitivity and high accuracy timing GPS module

The GT-86 is the high-sensitivity, high-accuracy timing GPS receiver.
The GT-86 supports TRAIM and Various position modes, allowing it to outputs accurate and robust 1PPS synchronized with UTC time.

New Product:GT-88 (Extremely high stability of 4.5ns (1sigma) using a single band receiver)

Features

Supports GPS, QZSS and SBAS

In addition to high position accuracy, GV-86 achieves superior performance as regular GPS Receiver Modules such as fast TTFF, highly improved Noise Tolerance
Galileo Ready. The software can be upgraded to support concurrent Multi-GNSS reception with GPS, Galileo, QZSS and SBAS

Simultaneous output of time pulse (1PPS) and low jitter clock (configurable, 4 kHz to 40 MHz) synchronized with the 1PPS

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

1PPS stability: 15 nsec (1σ)

Single satellite tracking capable operations (except Navigation Mode)

Detect/Disable low integrity satellites (TRAIM function)

Suitable for infrastructure development which needs high integrity.

Improved Noise Tolerance

Reduces effects of internal and external noise

Embedded Flash ROM

Suitable for long-term use backed by FURUNO’s continuous support and function enhancement

Enhance performance in combination with recommended antenna

Multi-GNSS antenna AU-217 receives GPS signal (L1 band) and GLONASS signal (G1 band), and has highly noise resistant as well as highly environmental resistant equivalent to IP67. Multi-GNSS antenna AU-217 is suitable for use with Furuno timing Multi-GNSS modules and disciplined oscillators.
