Quectel’s GNSS LC76F module supports concurrent reception of GPS, GLONASS (or BeiDou) and QZSS satellite signals. Capable of acquiring and tracking any mix of GPS, GLONASS (or BeiDou) and SBAS signals, it is designed to be compatible with Quectel’s L76, L76-L and L76-LB modules, allowing convenient migration between them.

The integrated LNA (low-noise amplifier) provides improved sensitivity, improved accuracy, fast tracking and acquisition of signals, and can maintain enhanced performance in challenging environments. Compared with GPS-only systems, multiple GNSS systems increase the number of visible satellites, reducing the time-to-first-fix and improving positioning accuracy, even in dense urban canyons.

Combining advanced AGNSS (Assisted GNSS) technologies and low-power modes, the LC76F achieves high performance, low power consumption and fully meets industrial standards. Its performance makes it ideal for industrial PDAs and various consumer and industry applications, and its extremely low power consumption makes it an excellent solution for power-sensitive applications, especially portable devices.

Other features include high sensitivity of -165 dBm during tracking and -148 dBm during acquisition, support for multi-tone active interference cancelation, and UART as well as I2C interfaces.
