LC29D

2 Introduction

The GNSS board is a compact board for GNSS applications. It features a concurrent multi-constellation

GNSS receiver on dual GNSS bands, an integrated 6-axis sensor, fusion with Real-Time Kinematic (RTK)

and Dead-Reckoning (DR). The module can achieve sub-meter-level accuracy in open-sky areas.

The GNSS board can work on L1 and L5 bands for GPS, Galileo and QZSS, L1 band for GLONASS and BeiDou,

and L5 band for IRNSS. This greatly increases the number of satellites which can be involved in tracking

and positioning, thereby significantly reducing the multipath effect from tall buildings in urban

environments, reducing signal acquisition time and improving positioning accuracy. In addition to this the

GNSS module’s on-board LNAs and SAW filters serve to ensure better positioning in weak signal areas and

harsh environments.

The GNSS module’s combination of compact design, low power consumption and high performance

makes it a popular choice for real-time tracking systems for vehicles, people and assets, as well as for

sharing economy applications

Feature Highlights

• Support dual-band and multi-constellation

• Supports GPS/BeiDou/GLONASS/Galileo/IRNSS/QZSS

• High-performance, high reliability positioning engine. It facilitates a fast and precise GNSS

positioning capability.

• Supports serial communication interfaces UART and SPI.

• Integrates a 6-axis MEMS sensor and supports sophisticated Real-Time Kinematic (RTK) and

Dead-Reckoning (DR) algorithms to fuse the sensor data, GNSS raw data and speed data, etc. to

provide sub-meter level positioning accuracy in an open-sky environment

• Support AGNSS

• Embedded flash memory provides the capacity for storing user-specific configurations and

future firmware updates.
