Ultra-Small Dual-Band

Multi-Constellation GNSS Module

9.7mm

2.4mm

Featuring a concurrent mulꢀ-constellaꢀon 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 posiꢀoning, thereby signiﬁcantly reducing the mulꢀpath eﬀect caused by tall buildings in urban environments,

reducing signal acquisiꢀon ꢀme and improving posiꢀoning accuracy.

LC79D is AIS-140 compliant, and its on-board LNAs and SAW ﬁlters serve to ensure beꢁer posiꢀoning in weak signal areas

and other harsh environments. The GNSS chipset using 28nm process technology, coupled with the advanced low-power

management soluꢀon, enables low-power GNSS sensing and posiꢀoning determinaꢀon and makes the module an ideal

soluꢀon for power-sensiꢀve and baꢁery-powered systems.

Due to its excellent performance in improving posiꢀon driꢂ and enhancing posiꢀoning accuracy in rough urban canyons,

LC79D has become a popular selecꢀon for real-ꢀme tracking systems, sharing economy applicaꢀons and so on.
