LC79D is a high performance GNSS module supporng mul-constellaon GNSS and dual GNSS bands. It can acquire and
track GPS, GLONASS, IRNSS, BeiDou, Galileo and QZSS signals. The module can work at L1 and L5 Bands for GPS and GALILEO
satellites.
Compared with the GNSS module working at L1 band only, LC79D can generally increase the number of visible satellites,
reduce TTFF and enhance posioning accuracy, especially when driving in rough urban environments.
LC79D achieves exceponal performance both in acquision and tracking, and fully meets the industrial standard. With
embedded LNA, dual antennas and antenna switch funcon, it is an ideal product for automove, consumer and industry
tracking applicaons.
