# GNSS LC79H series ## Summary - Dual-band GNSS module with optional RTK - 10.1 mm × 9.7 mm × 2.4 mm - 0.5g - GPS, GLONASS, BDS, Galileo and QZSS - Operating temperature of -40°C to +85°C ## Key features - Multi-GNSS engine for GPS, GLONASS, BDS, Galileo, and QZSS - Dual-band (L1 + L5) - Integrated LNA for high sensitivity - Support fast convergence dual-band RTK technology (optional) - Integrated SAW filter for noise cancellation - Supports EPO, EASY, and LOCUS functions - UART and I2C - Integrated AIC, jamming, and OSNMA features ## Overview The LC79H is a series of concurrent multi-constellation GNSS modules. LC79H (AL) is a dual-band GNSS module supporting reception of GPS, GLONASS, Galileo, BDS, NavIC, and QZSS signals. LC79H (EL) provides enhanced capability by utilizing dual-band positioning combined with RTK technology, delivering centimeter- and decimeter-level high-precision positioning. With the integrated AGNSS function and the ability to receive SBAS broadcast signals, the LC79H series provides users with a fast, accurate, and high-performance positioning experience. Compared to single constellation GPS receivers, by enabling multiple GNSS constellations, the LC79H series 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 series 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 LNA 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. With the low power consumption and high precision, the LC79H series 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. ##
