G-Mouse GPS Receiver

General Description

The HR-45D-33P01-P07 is a complete GPS&Beidou engine module that features super sensitivity,ultra low power and small form factor. The GPS&Beidou signal is applied to the antennainput ofmodule, and a complete serial data message with position, velocity and time information is presentedatthe serial interface with NMEA protocol or custom protocol.

Its –165dBm tracking sensitivity extends positioning coverage into place like urbancanyonsand dense foliage environment where the GPS&Beidou was not possible before. The small formfactorand low power consumption make the module easy to integrate into portable device like DVR, UVA,Car trackers and PNDs.
