## Overview
The LC98S is a multi-constellation GNSS module that delivers high integrity, precision timing in demanding applications worldwide. It supports GPS, GLONASS, Galileo, BDS and QZSS constellations, and can acquire and track three GNSS systems and QZSS concurrently. Its timing functionality can be maintained even while tracking a single satellite.

The LC98S satisfies the requirements for industrial timing applications on power grids and is an ideal solution for timing of 5G/O-RAN networks.

The integrated AGNSS feature can improve the signal acquisition process and shorten the time needed to achieve a first position fix and output an accurate and stable PPS pulse. The module also features a high dynamic range receiver with both analog and digital interference mitigation, enabling applications in wireless communications equipment.

The LC98S internal chip is compliant with the “AEC-Q100” qualification. Our strictly controlled manufacturing and testing processes guarantee the high quality of each module.
