FAQ: What NMEA messages does ArcPad support?

Question

What NMEA messages does ArcPad support?

Answer

ArcPad recognizes the following NMEA-0183 (National Marine Electronics Association) version 2.0 or higher sentences:

Sentence TitleDescription
$GPGGAGPS fix data
$GPGLLGeographic position, latitude and longitude
$GPGSAGPS Dilution of Precision (DOP) and active satellites
$GPGSVGPS satellites in view
$GPRMCRecommend minimum specific GPS/TRANSIT data
$GPRRERange residual error
$GPVTGTrack made good and ground speed
$GPZDATime and date
$PGRMEEstimated error information (Garmin Proprietary)
$PGRMTSensor Information (Garmin Proprietary)
$PMGNVERGPS hardware and software version numbers (Magellan Proprietary)
$PASHR,POSPosition information (Ashtech Proprietary)
$PASHR,SATGPS satellite tracking status information (Ashtech Proprietary)
$PRWIRIDVersion Information (Rockwell Proprietary)
$PRWIZCHChannel Status(Rockwell Proprietary)
$SDDPTDepth, in meters
$SDMTWWater Temperature, in degrees Celsius


The NMEA-0183 version 3.0 standard adds the following additional values for the $GPGGA fix quality, which ArcPad recognizes:

  • 4 = Real Time Kinematic (RTK) fixed solution
  • 5 = Real Time Kinematic (RTK) float solution
  • 6 = Estimated dead reckoning
  • 7 = Manual input mode
  • 8 = Simulation mode
Note:
Most GPS receivers output a limited number of NMEA-0183 sentences. ArcPad uses data from a number of NMEA-0183 sentences to display all information in the GPS Position Window as well as to populate the fields associated with the GPS Tracklog. When information is not displayed in the GPS Position Window it is usually the result of ArcPad not receiving the required NMEA-0183 sentence from the GPS receiver.
