GNSS LG77L A

The LG77L is a series of GNSS modules which supports concurrent reception of GPS, GLONASS (or BeiDou), Galileo, and QZSS. It can acquire and track any mix of GPS, GLONASS (or BeiDou), Galileo and SBAS signals. Compared with single GPS systems, enabling multiple GNSS systems increases the number of visible satellites, reducing the time-to-first-fix and improving the positioning accuracy, especially when driving through dense urban canyons.

By combining EASY™ (Embedded Assist System), an advanced AGNSS feature, with GLP (GNSS Low Power), a low-power mode, the LG77L achieves high performance, low power consumption and fully meets industrial standards. The EASY™ technology allows the module to calculate and predict orbits automatically by using the ephemeris data (of up to 3 days duration) which are stored in the internal RAM. As a result, the LG77L can acquires a fix position quickly, even at lower signal levels with low power consumption. With the GLP technology, on the other hand, the LG77L 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.

Its enhanced performance makes the LG77L ideal for industrial PDAs, consumer and industry applications. Extremely low-power consumption makes it a great solution for power-sensitive applications, such as portables.
