Frequently Asked Questions
Q: What is the LC29H Dual Band L1+L5 RTK GNSS Module used for?
A: The LC29H is a high-precision RTK GNSS core board module used in applications that require centimeter-level positioning accuracy, such as precision agriculture, drone navigation, autonomous vehicles, land surveying, GIS mapping, and robotics. It supports GPS, BeiDou, Galileo, and GLONASS satellite constellations across both L1 and L5 frequency bands.
Q: What is RTK differential positioning and why does it matter?
A: RTK (Real-Time Kinematic) differential positioning is a satellite navigation technique that uses a base station transmitting correction data (RTCM) to a rover receiver. By processing these corrections in real time, the LC29H module achieves centimeter-level accuracy — far superior to standard GPS which typically has meter-level accuracy. This makes it essential for professional surveying, precision farming, and autonomous navigation.
Q: What is the advantage of dual-band L1+L5 reception?
A: Dual-band (L1 + L5) reception allows the module to receive signals on two different frequencies simultaneously. This significantly reduces multipath errors — where signals bounce off surfaces before reaching the receiver — and improves performance in environments with obstructions, like urban canyons or areas with heavy tree cover. The result is faster RTK initialization and more stable, accurate positioning.
Q: Is the LC29H compatible with standard GNSS correction services?
A: Yes. The LC29H module supports RTCM correction data input, making it compatible with most commercial and open-source RTK base stations and NTRIP correction streaming services. This gives you the flexibility to use it with a wide range of existing infrastructure and software platforms.
Q: What does the package include?
A: Each order includes 1 x LC29H Dual Band L1+L5 RTK GNSS Core Board Module. Please ensure you have compatible antennas, correction data sources, and interface hardware for your specific integration project.
