The LC76G Series from Quectel are GNSS Modules that support GPS, GLONASS, BDS, Galileo, and QZSS constellations. They have a cold start of 15 s, a warm start of 2 s, and a hot start of 2 s. These GNSS modules have an acquisition sensitivity of -147 dBm, tracking sensitivity of -166 dBm, and reacquisition sensitivity of -159 dBm. They can measure altitude, velocity, and acceleration while operating at a maximum altitude of 10000 m, maximum velocity of 500 m/s & maximum acceleration of 4g. The modules have a horizontal position accuracy of 2 m, velocity accuracy of 0.1 m/s, and acceleration accuracy of 0.1 m/s2. These GNSS modules require a DC supply of 3.3 V and consume less than 36 mA of current. They can be controlled via I2C (up to 400 kbps) and UART (adjustable from 9600-912600 bps) interfaces.
The LC76G Series of GNSS modules have an integrated LNA to deliver high sensitivity effectuates, high accuracy positioning, fast signal tracking & acquisition, and better module performance even in challenging environments. They also have an embedded multi-tone active interference canceller for anti-jamming. These GNSS modules support WAAS, EGNOS, MSAS, and GAGAN SBAS constellations. They support EASY (Embedded Assist System), an advanced AGNSS feature, with GLP (GNSS Low Power), a low-power mode, to achieve high performance with low power consumption and fully meet industrial standards. The EASY technology allows these modules to calculate and predict orbits automatically by using the ephemeris data (duration of up to 3 days) stored in the internal RAM. As a result, these modules acquire a position fix quickly, even at lower signal levels with low power consumption. The GLP technology enables these modules to adaptively adjust the on/off time based on the environmental and motion conditions to achieve a balance between positioning accuracy and power consumption. They are available in a package that measures 10.1 x 9.7 x 2.4 mm and have an antenna interface for active or passive antennas. These modules are ideal for consumer, industrial, and power-sensitive (like portables) applications.
