Overview

The LC29D is an ultra-compact GNSS module measuring 12.2mm × 16.0mm × 2.4mm which features a concurrent multi-constellation GNSS receiver on dual GNSS bands, an integrated 6-axis sensor, fusion with RTK and dead-reckoning. The module can achieve sub-meter-level accuracy in open-sky areas.

The LC29D 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 module’s on-board LNAs and SAW filters serve to ensure better positioning in weak signal areas and harsh environments.

The LC29D’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.
