The Tracker HAT for Raspberry Pi is specially designed for tracking applications. It includes necessary parts to ease develop the location-based applications. Accurate GPS positioning with built-in LNA provides better sensitivity. Quad-band GSM/GPRS module at heart of the board will provide reliable data connectivity across the globe. With the embedded antennas, no need for the mess of antenna cables and connectors right out of the box. As the power-sensitive projects need advanced power controls and sleep mode feature which come with that board.

Description

The Raspberry Pi GPRS/GPS Tracker HAT is based on Quectel’s M95 GSM/GPRS module with L96 GNSS/GPS. Built-in unique QuecFOTA™ technology allows M95 to update the firmware remotely. Additional features such as integrated TCP/IP protocol stacks, serial multiplexer and enhanced AT commands guarantee the fast and reliable transmission of data and SMS via GSM/GPRS network and extend the functionality of the application at no additional cost. Combining advanced AGPS called EASY™ (Embedded Assist System) and proven AlwaysLocate™ technology, L96 fully meets the industrial standard and provides greatly reduced TTFF and ultra-low power consumption.

EASY™ technology allows L96 to calculate and predict orbits automatically using the ephemeris data (up to 3 days) stored in internal flash memory, so the module can fix position quickly even at low signal levels and provide low power consumption. With AlwaysLocate™ technology, L96 can adaptively adjust the ON/OFF time to achieve a balance between positioning accuracy and power consumption according to the environmental and emotional conditions. Its super performance makes L96 ideal for automotive, industrial and consumer applications. Extremely low power consumption makes it easier to be applied to power sensitive devices, especially portable applications. We combined these two awesome modules on one board to make location-based applications on Raspberry Pi
