Antenna Module BeiDou DG2525-B

General Description

  Delin Comm DG2525-B module series is a family of stand alone GPS&Beidou receivers featuring the high performance GK9501 positioningengine.These flexible and cost effective receivers offer numerous connectivity options in aminiature 25.5x25.5x8.8mm package.Their compact architecture and power and memory options make DG2525-B modules ideal for battery operated mobile devices with very strict cost and space constraints. 

The 66-channel GK9501 positioning engine boasts a Time-To-First-Fix (TTFF) of under 1 second.The dedicated acquisition engine,with over 1 millioncorrelatorsis capable of massive parallel time/frequency space searches,enabling it to find satellites instantly. Innovative design and technology suppresses jamming sources and mitigates multipath effects, giving DG2525-B GPS&Beidou receivers excellent navigation performance even in the most challenging environments. 

DG2525-B modules are not designed for life saving or supporting devices or for aviation and should not be used in products that could in any way negatively impact the security or health of the user or third parties or that could cause damage

to goods.

1.2 Power Supply

 Regulated power for the DG2525-B 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 3.3V~5.5V, Recommended power supply voltage is 3.3V . maximum current is 45mA. 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 GOKE proprietary commands input.

2 Application

The module is equipped with a 4-pin 1.25mm distance Connector that connects to your application platform.
