Overview

The GT-88 is a high-performance multi-GNSS receiver module developed by Volgen in collaboration with Furuno, designed for precision timing and positioning. It supports GPS, GLONASS, and Galileo constellations simultaneously, providing robust navigation performance with a high-sensitivity -148dBm tracking capability. The module operates at 3.3V and communicates via a standard UART interface, making it suitable for integration into industrial and professional-grade systems.

Why Choose This Part

The GT-88 excels due to its triple-constellation support, which significantly improves signal availability and accuracy compared to GPS-only modules. Its low power consumption of 68mA and wide operating temperature range from -40C to 85C make it highly reliable for demanding outdoor environments.

Applications

Infrastructure Timing
Providing high-precision pulse-per-second (PPS) signals for synchronizing communication networks and power grids.
Industrial Navigation
Reliable positioning for heavy machinery and autonomous industrial vehicles in challenging RF environments.
Asset Tracking
Long-term tracking for high-value logistics where multi-constellation support ensures visibility in urban canyons.
Scientific Instrumentation
Time-stamping data for remote sensor nodes that require synchronization across wide geographic areas.

Getting Started

To begin development, connect the GT-88 module's UART pins to a 3.3V TTL-to-USB converter to monitor NMEA data on a PC. Ensure the 3.3V supply is stable and clean to maintain receiver sensitivity, and connect an appropriate active or passive antenna to the RF input. Use standard terminal software or GNSS evaluation tools to configure output rates and constellation settings via the serial interface.
