C.1 Position Logs
C.1.1 NMEA Logs
The NMEA logs (receiver outputs) supported by the SMART6 are summarized in Chapter 3 of the OEM6
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
OEM6 Family Firmware Reference Manual .
The steps for configuring the receiver output, through the command line are:
1. Configure the communication port using the SERIALCONFIG command, described in Section B.8,
SERIALCONFIG Configures serial port settings on page 68. To set COM port 2 as follows:
enter the following string:
serialconfig com2 9600 n 8 1 n on
2. Select and configure the NMEA string to output. The information is described in Chapter 3 Data Logs of
the OEM6 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 LOG Request Logs from the
Receiver on page 63.
The above command line operations can also be carried out through NovAtel Connect. Information about
configuring the communication port can be found in 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 .
