Satellite GPS GNSS Receiver Module Antenna Car DVR Rearview Mirror GPS Gnss Antenna

General Description

The HR-45R-20W015 module series is a family of stand alone GPS receivers featuring the high performance UBX 7 positioning engine. These flexible and cost effective receivers offer numerous connectivity options in aminiature 45x38x13mm package.Their compact architecture and power and memory options make HR-45R-20W015 modules ideal for battery operated mobile devices with very strict cost and space constraints.

The 56-channel UBX M8 positioning engine boasts a Time-To-First-Fix (TTFF) of under 1 second. T he dedicated acquisition engine,with over 1 million correlatorsis capable of massive parallel time/frequency s pace searches,enabling it to find satellites instantly. Innovative design and technology suppresses jamming sources and mitigates multipath effects, giving HR-45R-20W015 GPS receivers excellent navigation performance even in the most challenging environments.

1.1 Key Features

1.2 Power Supply

Regulated power for the HR-45R-20W015 is required. The VCC Pin Need a stable DC voltage supply. Power supply ripple must be less than 30mV. The input voltage Vcc should be 3.0V~5.0V, Recommended power supply voltage is 3.3V . maximum current is 25mA. Suitable decoupling must be provided by external decoupling circuitry.

 1.3 UART Ports

The module supports two full duplex serial channels UART. All serial connections are at 3V CMOS logic levels, if need different voltage levels, use appropriate level shifters. The baud rate of both serial ports are fully programmable, the data format is however fixed: X, N, 8, 1, i.e. X baud rate, no parity, eight data bits and one stop bit, no other data formats are supported, LSB is sent first. The modules default baud rate is set up 9600bps, however, the user can change the default baud rate to any value from 4800 bps to 115kbps. UART port can be used for firmware upgrade, NMEA output and UBX proprietary commands input.

 2 Application

The Gmouse is equipped with a Micro 9*10 Pin connects to your application platform.

The HR-45R-20W015 Gmouse It consists of a UBX-G7020-KT single chip GPS IC which includes the RF part and Baseband part, a patch antenna, a LNA, a SAW filter, a TCXO, a crystal oscillator, Also comes with a 0.22F crystal capacitor ,can backup satellite ephemeris about 2 hour.
