Appendix C Logs
C.1 Position Logs
C.1.1 NMEA Logs
The NMEA logs (receiver outputs) supported by the AG-STAR are summarized in the OEMStar Firmware
Reference Manual. The available logs include:
• GPGGA, which outputs a log of position system fix data and undulation. There are variants of
GPGGA, specifically:
- GPGGALONG, which has both greater precision and the undulation field
• GPVTG, which outputs track made good and ground speed
The steps for configuring the receiver output, through the command line are:
1. Configure the communication port using the COM command, described in Section B.2, COM Configure
COM Port on page 50. 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. 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 Section B.4, LOG Request Logs
from the Receiver on page 53.
The above command line operations can also be carried out through NovAtel Connect. Information about
configuring the communication port can be found in the NovAtel Connect online help. The procedure for
adding a NMEA log through NovAtel Connect is summarized as follows:
1. In the Logging control window, click Logging to one or more of the receiver's serial ports. The Add Log
window displays.
2. Beside Select list, select Complete List or NMEA List.
3. Beside Log to file, select the NMEA log you want to add.
4. Select the port.
5. Configure the remaining fields then click Add.
