3.6 GPS Data Logging
Certain applications require that GPS data be retrieved in a timely manner. There are two available options
for this purpose.
FTP Data Logging
Real Time Data
3.6.1 FTP Data Logging
Data can be recorded and stored on the 4380A and can be retrieved via a FTP client (username: ftp,
password: ftp). The logs that are stored are determined by the user and can be one of any of the ASCII logs
specified in the Novatel OEMV user manual. To set up data logging users will need to follow the steps
outlined below to set up the type of data to be logged, log file intervals, maximum number of log files to
store, set up the filename schema, set the file compression on or off, and then turn the logging on. Users
can also verify the data logging configuration settings.
The OEM6 user manual is also available at: (
A.
Access the system via the command port.
B.
Use the
log ftp <novalog>
command to set up they data type to be sent over the data port. The
novalog
text on the command line specifies which data type to forward over this port. Some
examples are provided below.
4380A> log ftp timea ontime 1
ionutca onchanged
// log IONO & UTC data
rawalma onchanged
// log almanac on startup
rangea ontime 60
// L1/L2 observations @ 60 seconds
C.
Set the interval for the log file to the desired value using the
log_interval
command. Log interval
value is in minutes and can be between 1 and 30 minutes. Default is 15 minutes.
4380A>log_interval 15

D.
Set the maximum number of log files for the system to hold in memory using the
log_number
command. If the logs in the storage directory exceed the maximum number
of logs then the oldest
log will be deleted to ensure that there is room for new logs. Default is 100 log files.
4380A>log_number 4

Note:
Your data retrieval setup will need to take these values into account. The maximum time the
logs will be available on the system is the log_interval * log_files, in the examples above that is 60
minutes. If you are not retrieving the files frequently enough you will lose data.
E.
Use the
log_filename (user|timestamp)
to set up the file naming scheme. Default is
timestamp
.
a.
When using the
user
file naming scheme you will also need to provide the file prefix, the
number of digits you would like to use as the unique file identifier, and the suffix for the file.
