GSY-GM-220-III L GNSS Precision Timing Module

Introduction

GNSS Precision Timing Module a BDS/GPS dual-mode timing module for power telecommunication timing applications. Among them, the low-power GNSS SoC chip, based entirely on independent intellectual property rights, is a fully built-in BDS/GPS timing module on the market. It has accurate timing and high reliability, and is suitable for satellite-scale applications.

Features

Precision timing, 1PPS accuracy is better than 20ns
Support single-star timing mode, even if only one visible satellite can maintain a reliable timing
Supports timing data protocol, instruction control
Compact design, small size
Compatible with mainstream GPS timing modules to save replacement costs
SMD surface mount package for easy production

Applications

Telecom base station timing
Power timing
LAN time synchronization
