Quectel LC76F GNSS Tiny Module - SATRON electronics
Quectel LC76F
GNSS Module
  • 10.1mm × 9.7mm × 2.3mm
  • 0.3g
  • GPS, GLONASS (or BeiDou) and QZSS
  • Operating temperature of -40°C to +85°C

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, accuracy, fast tracking and acquisition of signals, and maintains enhanced performance in challenging environments. Compared with single GPS receivers, multiple GNSS constellations increase the number of visible satellites, reduce the Time To First Fix and improve positioning accuracy, even in 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.
