Quectel LG77L GNSS module supports concurrent reception of GPS, GLONASS, BeiDou and QZSS. With 33 tracking channels, 99 acquisition channels and 210 PRN channels, it can acquire and track any mix of GPS, GLONASS (or BeiDou) and SBAS signals.

Compared with single GPS system, enabling multiple GNSS systems generally increases the number of visible satellites, reduces the time to first fix and increases positioning accuracy, especially when driving in rough urban environments. Combining advanced AGNSS feature such as EASY™ (Embedded Assist System) and low-power modes such as GLP (GNSS Low Power), LG77L achieves high performance, low power consumption and fully meets the industrial standards. EASY™
technology allows the module to calculate and predict orbits automatically using the ephemeris data (up to 3 days) stored in internal RAM, so LG77L can fix position quickly even at lower signal levels with low power consumption. With GLP technology, LG77L can adaptively adjust the on/off time to achieve a balance between positioning accuracy and power consumption according to the environmental and motional conditions.

Its super performance makes LG77L ideal for industrial PDA, consumer and industry applications. Extremely low power consumption makes it a great solution for power-sensitive applications, especially portable devices.
