Export of ground speed and track

[Holton181]

Hi,

I'm fiddling with a script to export NMEA (GPS) sentences (for my own aircraft) to any external application/device that can use them, like my android phone.

 

 

All is working (coordinates doesn't really fit with real world though, can be more than 500m off), but I can't find how to get my ground speed and track direction right. Is there a way to export them? At the moment I'm using TAS and a calculated value for the track using my coordinates (formula is for real, spherical world and gives a couple of degrees off).

Or as an alternative, is it possible to export data from the NS430?

 

 

Note, when I say track direction, I mean the direction I'm actually traveling, not heading.

 

 

Thanks!

I wonder if Tacview advanced might help ?

Can it export NMEA sentences?

Also, it would be a rather expensive solution for this little gimmick alone...

Solved!

Got a tips from @BR=55=Sevas to simply use LoGetVectorVelocity = {x,y,z}. Some simple Pythagoras and arctan and all done. Almost feel a bit embarrassed by this simple solution, not figuring it out myself.
