# GNSS LC29H series
## Key features
- Multi-GNSS engine supporting GPS, GLONASS, BDS, Galileo, NavIC and QZSS
- Concurrent reception of L1 and L5 GNSS band signals
- Optional RTK functionality offering centimeter-level accuracy within seconds
- Optional integrated dead reckoning (DR) function for enhanced position availability in GNSS-denied areas, supporting both 4-wheel and 2-wheel applications
- Support for GNSS and IMU raw data
- LC29H (AA) includes Galileo OSNMA anti-spoofing technology
## Overview
LC29H is a series of dual-band, multi-constellation GNSS modules that support the concurrent reception of all four global GNSS constellations: GPS, BDS, Galileo, NavIC and GLONASS. Compared to GNSS modules that track only L1 signals, the LC29H series can receive and track a higher number of visible satellites in multi bands, thereby significantly mitigating the multipath effect in deep urban canyons and improving positioning accuracy. By having an internal LNA and SAW filter, the module achieves better sensitivity and anti-interference capability. Featuring dual frequency support, the module delivers CEP accuracy values of 1m in autonomous mode and centimeter levels in the RTK capable variants. The optional dead reckoning function ensures the module’s superior positioning performance even in weak signal areas or when GNSS signals are not available.
Based on the receiver chip using 12nm technology, the LC29H series provides advanced power management enabling low-power GNSS sensing and position fixing, which makes the module an ideal solution for power-sensitive and battery-powered systems. Featuring high-precision positioning and low power consumption, the LC29H series is perfectly suited for applications such as real time tracking and sharing economy related services.
