Driver for decoding the Javad NAVPOS message.
This driver can be used as a positioning system but can also decode the quality of the data link, which is used for differential corrections.
The horizontal velocity can also be decoded as a speed.
- 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:
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.
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.
