Quectel LG77L Extremely Compact Multi-Constellation GNSS Module with Ultra-Low Power Consumption - Version:1.3
■Compared with single GPS systems, enabling multiple GNSS systems increases the number of visible satellites, reduces the time to a first fix and improves 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 module achieves high performance, low power consumption and fully meets the 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 acquire 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 the industrial PDA, consumer and industry applications.
Extremely low-power consumption makes it a great solution for power-sensitive applications, such as portables.
