3.6.1 FTP Data Logging
Data can be recorded and stored on the ATS-6501 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 OEMV user manual is 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.
ATS-6501> 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.
ATS-6501>log_interval 15
OK
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.
ATS-6501>log_number 4
OK
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.
