LC76GABMD
The LC76GABMD is Quectel's multi-GNSS positioning module based on the AG3352 chipset, supporting concurrent reception of GPS, GLONASS, BeiDou, Galileo, and QZSS in the L1 band. With -166dBm tracking sensitivity and 28s cold-start time-to-first-fix, it delivers robust, reliable positioning even in weak-signal environments. The compact LCC-28 package (9.7 x 10.1mm) and UART/I2C interfaces make it easy to integrate, while pin-compatibility with the earlier L76 and L76-LB modules enables seamless migration. It is the ideal GNSS engine for IoT asset tracking, wearables, vehicle navigation, and industrial positioning applications.

Product Details
Multi-Constellation Concurrent Reception
The LC76GABMD receives five GNSS constellations simultaneously in the L1 band. By tracking more satellites at once, it achieves faster fixes, higher accuracy, and better availability than single- or dual-constellation receivers.
Why it matters: In urban canyons or dense foliage where sky view is partially blocked, having GPS + GLONASS + BeiDou + Galileo + QZSS simultaneously means the receiver can maintain a fix using whichever satellites remain visible, dramatically improving reliability.
AG3352 Chipset: The enhanced AG3352 processing core delivers -166dBm tracking sensitivity and 28s cold-start TTFF, with low power consumption suited for battery-operated tracking devices.
Key Applications

Frequently Asked Questions
What is the LC76GABMD used for?
A multi-GNSS positioning module for IoT asset tracking, wearables, vehicle navigation, and industrial positioning. It receives GPS, GLONASS, BeiDou, Galileo, and QZSS simultaneously with -166dBm tracking sensitivity.
Which constellations does it support?
GPS, GLONASS, BeiDou (BDS), Galileo, and QZSS — all in the L1 band, received concurrently. Multi-constellation reception improves accuracy and reliability versus single-constellation receivers.
Is it pin-compatible with L76 and L76-LB?
Yes. The LC76G is designed to be pin-compatible with the earlier Quectel L76 and L76-LB modules, allowing smooth migration to the newer AG3352-based LC76G without PCB redesign.
Does it include an antenna?
No. An external GNSS antenna is required (not included). Pair with a suitable L1-band antenna such as the Quectel YFGA015E3AM ceramic patch antenna for optimal reception.
What interfaces does the module use?
UART and I2C interfaces for host communication. The UART provides NMEA position data output; I2C is available for lower-pin-count designs. Supply voltage is 2.55V to 3.6V.
