HR-56R G-Mouse Mini USB GPS GNSS Receiver

Overview

The HR-56R-MT is a complete GPS&Beidou engine module that features super sensitivity, ultralowpower and small form factor. The GPS&Beidou signal is applied to the antenna input of module, andacomplete serial data message with position, velocity and time information is presented at the serial interfacewithNMEA protocol or custom protocol.

Its –165dBm tracking sensitivity extends positioning coverage into place like urban canyons anddensefoliage environment where the GPS&Beidou was not possible before. The small form factor and lowpowerconsumption make the module easy to integrate into portable device like PNDs, UVA, DVR,Car Tracker andvehicl navigation systems.
