GPSx2.exe

 

    The above link is for a fully functional trial version.

Created in C/C++ with U++ in TheIDE.
http://www.ultimatepp.org/

    This application will search for and connect to GPS receivers.
If there are more than one then the best signal will be used as GPS and the other as GPS2.
This can be used to check the reception of one receiver compared to another.

This will allow tracking with the app NLNww.jar.
The main purpose will be to have a radio receiver, like ADSB, to show many tracks for collision avoidance.
It can also be used for Differential GPS survey data.

With the software that came with your GPS receiver you should check that it is working correctly and that
it is sending the GGA sentence.


The app has a toggle for Geoid correction of the Altitude, on by default.
Some receiver can/are set to do this, it is not sending the true NMEA GGA sentence.
Clicking "Alt +/-" for that receiver will compensate for this without resetting the receiver.

To be added:
1. If for some reason the signal is lost, common for Bluetooth, it will auto reset and continue.
2. The ability to record the track/s to a file.
3. More try/catch blocks in the app to handle errors when they are found or reported.
