Quectel LC76G Series Compact GNSS Module - SATRON electronics
Quectel LC76G
Compact GNSS Module
  • 10.1mm × 9.7mm × 2.4mm
  • 0.3g
  • GPS, GLONASS (or BeiDou) and QZSS
  • Operating temperature of -40°C to +85°C
Based on the latest enhanced chipset, Quectel’s new LC76G GNSS module supports concurrent reception of GPS, GLONASS, BDS, Galileo and QZSS. The LC76G is designed to be compatible with Quectel L76 and L76-LB modules, allowing for smooth migration between them.
Compared with single constellation receivers, by enabling multiple GNSS constellations, the LC76G module increases the number of visible satellites, reduces the time to first fix and improves positioning accuracy, especially when driving through dense urban canyons.
The integrated LNA that delivers high sensitivity effectuates high accuracy positioning, fast signal tracking and acquisition and better performance even in challenging environments.
By combining EASY™ (Embedded Assist System), an advanced AGNSS feature, with GLP* (GNSS Low Power), a low-power mode, the LC76G achieves high performance with low power consumption and fully meets the industrial standards. EASY™ technology allows the module to calculate and predict orbits automatically by using the ephemeris data (duration of up to 3 days) stored in the internal RAM. As a result, the LC76G acquires a position fix quickly, even at lower signal levels with low power consumption. Moreover, with the GLP* technology, the LC76G can adaptively adjust the on/off time based on the environmental and motion conditions to achieve a balance between the positioning accuracy and power consumption.
Due to its enhanced performance the LC76G is ideal for consumer and industrial applications, and extremely low power consumption makes it a preferred solution for power-sensitive applications such as portable devices.
