Frequently asked 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 Title | Description |
|---|---|
| $GPGGA | GPS fix data |
| $GPGLL | Geographic position, latitude and longitude |
| $GPGSA | GPS Dilution of Precision (DOP) and active satellites |
| $GPGSV | GPS satellites in view |
| $GPRMC | Recommend minimum specific GPS/TRANSIT data |
| $GPRRE | Range residual error |
| $GPVTG | Track made good and ground speed |
| $GPZDA | Time and date |
| $PGRME | Estimated error information (Garmin Proprietary) |
| $PGRMT | Sensor Information (Garmin Proprietary) |
| $PMGNVER | GPS hardware and software version numbers (Magellan Proprietary) |
| $PASHR,POS | Position information (Ashtech Proprietary) |
| $PASHR,SAT | GPS satellite tracking status information (Ashtech Proprietary) |
| $PRWIRID | Version Information (Rockwell Proprietary) |
| $PRWIZCH | Channel Status(Rockwell Proprietary) |
| $SDDPT | Depth, in meters |
| $SDMTW | Water 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.
