Data Logging Configuration

Use these settings to configure the data logging settings. Data logging can be configured if the Data Logging option is installed (see the Receiver Options menu).

Select Data Logging / Summary / Configure.

 

Session Name – This field displays the name of the session as DEFAULT. You cannot change it.

Enable – Select this check box to enable the session to operate after you tap OK.

Schedule – Each session logs data for starting at specific times, for a specified duration:

  • Always – This mode causes the session to log data whenever it is selected. A single file is produced. Logging only stops when the available file system space drops to zero or when the session is disabled.

  • Manual – Logging starts when the session is first enabled and continues for the specified duration. A single file is produced.

  • Once – Logging starts at a specified date and time and continues for the specified duration.

  • Daily – Logging starts each day at the specified time and continues for the specified duration. A new file is produced each day.

  • Continuous – Logging produces a continuous sequence of files of the given duration. Individual logging sessions starts at times that match the duration. For example, 2 hour files would start at 00:00, 02:00, 04:00, ... 20:00, 22:00, and repeats this schedule every day.

Start Date – This field becomes available when you select Once as the Schedule mode. Select the Year, Month, and Day when the session should start logging.

Start Time – This field becomes available when you select Once or Daily as the Schedule mode. Enter the time of day (HH:MM) when logging should start.

Duration – Available for all Schedule modes except Always. Specifies the amount of time, in minutes, for each logged file.

File Format – Select to have data logged in either T02 or T04 format.

Measurement Interval – Select the interval between logged GNSS measurement records.

Smooth Pseudorange – Select this check box to smooth pseudorange values in GNSS measurement records to reduce random fluctuations.

Smooth Phase – Select this check box to smooth carrier phase measurements in GNSS measurement records to reduce random fluctuations. This feature is only available for Measurement Intervals of 1 second and longer.

Smoothing includes primary and secondary satellite signals.

Position Interval – Select the interval between logged position records.

Log Received Corrections – The correction stream being used for positioning will be logged.

Voltage/Temperature Records – Set a time to record the receiver's voltage and temperature.

Log Raw Nav Data – Logs the raw 50 bps data sent from the satellite.

Log SBAS Data – Logs the SBAS (Satellite Based Augmentation System) data messages.

File System – Select the file system to be used for this session. On some systems, only a single choice is available.

Path Style – Select one of several directory structures for the created files:

  • Flat – Files are all created at the top-level directory of the selected file system. No subdirectories are used.

    NOTE – Some file systems (like USB memory sticks or CompactFlash cards) have limitations on the number of files that can be created in a top-level directory. If a large number of files will be created, do not use path style Flat.

  • Date – Files are stored in a structure of the form /Internal/YYYY/MM/DD/filename.<<T02 or T04>>. The date chosen corresponds to the expected start time of the session.

  • Date/Session – Files are stored in a structure of the form /Internal/YYYY/MM/DD/SessName/filename.<<T02 or T04>. The actual name of the session (up to eight characters) is used as part of the path.

  • Session/Date – Files are stored in a structure of the form /Internal/SessName/YYYY/MM/DD/filename.<<T02 or T04>. The actual name of the session (up to eight characters) is used as part of the path.

Name Style – Select a filename style. The file has a filename extension of T02 or T04.

  • ####JJJx – Creates an 8 character name consisting of the last four digits of the serial number (####), followed by:

    x is an index character that steps from 0 to 9 and then from A to Z.

  • ##########YYYYMMDDhhmm – Creates a 22-character name consisting of the full 10-digit serial number (##########), followed by:

    4-digit year (YYYY)

    2-digit month (MM, 01 = January)

    2-digit day-of-month (DD, 01 = first day of month)

    2-digit hour (00 to 23)

    2-digit minute (00 to 59)

    The time encoded is the theoretical start time when the file will be created. Typically, this is the start time of the session. However, if a scheduled file starts later than its scheduled time (for example, due to a power failure), the file will still be named as if it actually started on time.

  • SITEJJJh – NGS style for long durations. Only available for continuous logging sessions with durations that are exact 60 minute multiples. Creates an 8 character name where SITE is the last four characters of the Station Name entered on the Reference Station page, followed by:

    JJJ is the Julian Day of Year (001 for 01 Jan)

    h is an hour indicator character that steps from a to y (a = 00:00, b = 01:00, ..., y = 23:00)

  • SITEJJJhmm – NGS style for short durations. Only available for continuous logging sessions. Creates a 10 character name where SITE is the last four characters of the Station Name entered on the Reference Station page, followed by:

    JJJ is the Julian Day of Year ( 001 for 01 Jan)

    h is an hour indicator character that steps from a to y (a == 00:00, b = 01:00, ..., y = 23:00)

    mm is a 2-digit minute indicator (00 to 59)

  • YYMMDDHH – IGS style for long durations. Only available for continuous logging sessions with durations that are exact 60 minute multiples. Creates an 8 character name encoding the date and time of the file creation time, where:

    YY is the last two characters of the year.

    MM is the two digit month number, 01 = January.

    DD is the two digit day-of-month number.

    HH is the two digit hour within day, 00 to 23.

  • YYMMDDHHmm – IGS style for short durations. Only available for continuous logging sessions. Creates a 10-character name encoding the date and time of the file creation time, where:

    YY is the last two characters of the year.

    MM is the two digit month number, 01 = January.

    DD is the two digit day-of-month number.

    HH is the two digit hour within day, 00 to 23.

    mm is the two digit minute within the hour, 00 to 59.

FTP Push – If enabled, then at every rollover period, the receiver sends the logged data files to a predefined FTP server.

NOTE – Files that are pushed in this manner are always expanded to the filename format ##########YYYYMMDDhhmm unless they are already in that format. Any suffix character on the name is not changed.

Email Push – If enabled, then at every rollover period, the receiver sends the logged data files to a predefined email address.
