Javad and Topcon

The following describes the options available for this converter:

Perform pre-processing checks

If enabled, data is scanned after conversion to correct potential issues. See Pre-processing Checks for more information.

Use locktime records for cycle slip detection

Locktimes from the Javad receiver are used instead of those computed by the decoder. Enable this if Javad locktimes are problematic.

Use SAVE marker to store sites to .sta file

Markers are saved to an STA file.

Verbose messaging mode

Alerts you of warnings and errors that have occurred.

L2C phase correction

If your receiver logs L2C measurements, then the phase offset must be entered. If you are unsure, you can disable its usage.

Static/Kinematic Mode

This option controls how the static/kinematic flags are set in the final GPB file. Auto will set the entire file static or kinematic according to the detected processing environment.
