Database Setup

  • Add a Positioning Navigation System
    Select the Javad NAVPOS position and set the correct communication parameters.
  • Add a Miscellaneous System
    Select the Javad NAVPOS (Quality) and set the correct communication parameters. Three observations can be added and each must be given a slot number from the following table:

    Slot nr.



    Data link quality (%)


    Number of GPS satellites


    Number of GLONASS satellites

  • Add a Speed Log System
    Select the Javad NAVPOS Speed and set the correct communication parameters. Next, add a speed observation and give it a correct name. For the unit of the speed select km/h.


The Data Link Quality can be used in an Alert Display or in an Observation Physics Display.

Registry Options

The driver has one extra setting, which can block decoding for a while if the Javad system drops in position calculation mode.

This settings can be found in the Windows registry, at key:

HKEY_CURRENT_USER\Software\QPS\Qinsy\8.0\Drivers\DrvJavadGril\NAVPOS\Settings\Minimum Position Age [ms]

Default is 1000 ms = 1 second. So if the postitioning system drops in calculation mode, nothing is decoded for one second.
