Status: Released Key Features EMAIL US: info@quectel.com VISIT US: www.quectel.com Version: 1.0 Quectel LC76F Compact GNSS Module 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. Multi-GNSS engine for GPS, GLONASS (or BeiDou) and QZSS Industrial leading sensitivity of -165 dBm during tracking and -148 dBm during acquisition Integrated LNA for high sensitivity Supports anti-jamming and multi-tone active interference canceller Supports multiple low-power modes to ensure ultra-low power consumption Supports UART and I2C Interfaces 10.1 mm 9.7 mm AGNSS Technology Ultra Low Power Consumption Extremely Compact Size Super Tracking Sensitivity: -165 dBm Operating Temperature Range: -40 to +85 °C Anti-jamming RoHS Compliant Multi-GNSS System 2.3 mm
