NMEA Logs
The NMEA logs (receiver outputs) supported by the SMART-AG are summarized in Chapter 3 of the
OEMV Family Firmware Reference Manual in section "NMEA Standard Logs". The available logs
include:
•
GPGGA, which outputs a log of position system fix data and undulation. There are variants of
GPGGA, specifically:
-
GPGGARTK, which has greater precision than GPGGA but with the loss of the
undulation field
-
GPGGALONG, which has both greater precision and the undulation field
•
GPVTG, which outputs track made good and ground speed
Each of the available NMEA standard logs is described in more detail in its own section of Chapter 3
of the OEMV Family Firmware Reference Manual.
The steps for configuring the receiver output, through the command line are:
1. Configure the communication port using the COM command, described in Appendix B.2, COM
Configure COM Port on Page 66. To set COM port 2 as follows:
enter the following string:
com com2 9600 n 8 1 n off on
2. Select and configure the NMEA string that you want to output. The information is described in
Chapter 3 Data Logs of the OEMV Family Firmware Reference Manual, in the section for the
particular log. For example, to log gpgga (position system fix data and undulation) at 2 Hz, enter
the following string:
log gpgga ontime 0.5
You can configure the log to output at various frequencies, as described in Appendix B.4, LOG
Request Logs from the Receiver on Page 71.
