LC79H数据手册Quectel中文资料规格书

描述 Description

The LC79H features a concurrent multi-constellation GNSS receiver: the LC79H (AL) is a dual-band GNSS module supporting concurrent reception of GPS, GLONASS, Galileo, BDS, and QZSS signals by default, while the single band of the LC79H (BA) supports L1/B1 band for GPS, BDS, and QZSS satellites by default.

With the integrated AGNSS function and the ability to receive SBAS broadcast signals, the LC79H provides users with a fast, accurate, and high-performance positioning experience. Compared to single constellation GPS receivers, by enabling multiple GNSS constellations, the LC79H(BA) increases the number of visible satellites and improves the positioning reliability, in particular in dense urban environments.

As a dual-band, multi-constellation GNSS module, the LC79H (AL) tracks a higher number of satellites on dual frequencies, thereby significantly reducing the multipath effect caused by high-rise buildings in urban areas, reducing signal acquisition time, and improving positioning accuracy.

Embedded LNAs and SAW filters serve to ensure better positioning in challenging signal conditions. The advanced low-power management solution enables low-power GNSS sensing and positioning and makes the module an ideal solution for power-sensitive and battery-powered systems.

Due to the low power consumption and high precision, the LC79H is a popular choice for real-time tracking systems, ideal for sharing economy applications, and its superior performance makes it ideal for vehicle, personnel, and asset tracking.
