Product Description

 

General Description

The HR-2525-MTR is a complete GPS engine module that features super sensitivity, ultra low power and small form factor. The GPS signal is applied to the antenna input of module, and a complete serial data message with position, velocity and time information is presented at the serial interface with NMEA protocol or custom protocol.

 

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

 

Applications

- UVA(unmanned aerial vehicle)

- DVR(Digital Video Recording)

-Rearview Mirror DVR

-Car Tracker

1.2 Power Supply

Regulated power for the HR-2525-MTR 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 28mA. 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 PMTK proprietary commands input.

 

2 Application

 

The module is equipped with a 4-pin 1.25mm spacing connector that connects to your application platform. The HR-2525-MTR module It consists of a MediaTek MT3337 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.

3 NMEA 0183 Protocol

 

The NMEA protocol is an ASCII-based protocol, Records start with a $ and with carriage return/line feed. GPS specific messages all start with $GPxxx where xxx is a tHRee-letter identifier of the message data that follows. NMEA messages have a check sum, which allows detection of corrupTED data transfers.

 

The HR-2525-MTR supports the following NMEA-0183 messages: $GPGGA, $GPGLL, $GPGSA, $GP GSV, $GPRMC and $GPVTG.
