Positioning module with quick TTFF

29 June 2022 Telecoms, Datacoms, Wireless, IoT

Quectel Wireless Solutions’ LC76G is a single-band, compact GNSS module featuring fast and accurate location performance as well as ultra-low power consumption. Based on the Airoha AG3352 platform, it can concurrently receive and process signals from all constellations (GPS, GLONASS, BeiDou, Galileo and QZSS). This, in combination with the support of SBAS, greatly increases the number of visible satellites and enhances positioning accuracy.

The module can receive signals from up to 47 satellites and achieve 1,5 m positioning accuracy, representing a 40% improvement over previous generations of devices. Available in cost-optimised and low-power versions, the latter consumes less than 9 mA at 3 V with all four constellations enabled, allowing for a 72% reduction in power required than previously possible. This makes it attractive for battery-operated devices such as wearable personal trackers, wildlife and livestock tracking, and portable container trackers.

Integrated AGNSS technology reduces the time to first fix (TTFF) with a hot start taking less than 1 second, a warm start within 2 seconds, while the cold start can obtain accurate tracking fixes within 15 seconds.
