I. Overview

Quectel LC76F GNSS module supports concurrent reception of GPS, GLONASS (or BeiDou) and QZSS. It can acquire and track any mix of GPS, GLONASS (or BeiDou) and SBAS signals. LC76F is designed to be compatible with Quectel L76 and L76-L as well as L76-LB modules, allowing convenient migration between them.

The integrated LNA provides an improved sensitivity, as well as improved accuracy, fast tracking and acquisition of signals, and can keep enhanced performance under challenged environment. Compared with single GPS system, multiple GNSS systems increase the number of visible satellites, reduce the time to first fix and improve positioning accuracy, even in dense urban canyons.

Combining advanced AGNSS technologies and low-power modes, LC76F achieves high performance, low power consumption and fully meets the industrial standards.

Quectel LC76F’s superior performance makes it ideal for industrial PDA, consumer and industry applications. Extremely low power consumption makes it a great solution for power-sensitive applications, especially portable devices.
