Quectel LC76G GNSS positioning module

Quectel Wireless Solutions has released the LC76G module, a single-band compact GNSS module featuring fast location performance as well as ultralow power consumption.

Based on the Airoha AG3352 platform, the module can concurrently receive and process signals from all constellations (GPS, GLONASS, BeiDou, Galileo and QZSS), which in combination with the support of SBAS should increase the number of visible satellites. It can receive signals from up to 47 satellites and achieve 1.5 m (CEP50 open-sky) positioning accuracy.

The low-power version consumes less than 9 mA @3 V with all four constellations enabled, making it suitable for battery-operated devices such as wearable personal trackers, wildlife and livestock tracking, Toll tags, portable container trackers, and a host of traditional markets. Featuring an internal SAW filter and integrated LNA, the module can be connected directly to a passive patch antenna and provides filtering against unwanted interference, enabling good performance even while driving through dense urban canyons.

Integrated AGNSS technology EPO is supported on the module and reduces the time to first fix (TTFF) with a hot start taking less than 1 s, a warm start within 2 s, and a cold start that can obtain tracking fixes within 15 s. The fast GNSS fixes make it possible to use positioning and navigation services anytime and anywhere with small power budget.

While EPO requires manual download of predicted orbits, the module also supports EASY (Embedded Assist System), where predicted orbit information is collected directly from the satellites and provides for up to three days of accelerated fixes. Both EPO and EASY are available for each constellation.

Featuring an LCC form factor and a compact size of 10.1 x 9.7 x 2.4 mm, the footprint of the device is compatible with other industry solutions as well as Quectel’s legacy L76 and L76-LB modules, allowing for a smooth migration of existing designs to the latest low-power GNSS technology. The product can be combined with a selection of GNSS L1 antennas to enable various positioning requirements.
