Featuring a concurrent mul-constellaon GNSS receiver on dual GNSS bands, LC79D can work on L1 and L5 bands for GPS,
Galileo and QZSS satellites, L1 band for GLONASS and BeiDou satellites as well as L5 band for IRNSS satellite.
Compared with the GNSS modules working on L1 band only, LC79D greatly increases the number of satellites involved in
tracking and posioning, thereby signicantly reducing the mulpath eect caused by tall buildings in urban environments,
reducing signal acquision me and improving posioning accuracy.
LC79D is AIS-140 compliant, and its on-board LNAs and SAW lters serve to ensure beer posioning in weak signal areas
and other harsh environments. The GNSS chipset using 28nm process technology, coupled with the advanced low-power
management soluon, enables low-power GNSS sensing and posioning determinaon and makes the module an ideal
soluon for power-sensive and baery-powered systems.
Due to its excellent performance in improving posion dri and enhancing posioning accuracy in rough urban canyons,
LC79D has become a popular selecon for real-me tracking systems, sharing economy applicaons and so on.
