NMEA Logs
The NMEA logs (receiver outputs) supported by the SMART6-L 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.2,
SERIALCONFIG Configure COM Port
on page 48. To set COM port 2 as follows:
enter the following string:
serialconfig com2 9600 n 8 1 n off 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
Section B.4, LOG Request
Logs from the Receiver
on page 52.
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 the 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
