Baseline information (heading/attitude) with moving base

[quantenProjects]

I would like to use 2 GPS receivers mounted on a vehicle in a moving base configuration to get the heading of the vehicle (and the position in "single" accuracy).

It works with rtknavi not perfect but okay. I can see the baseline length and orientation in the graph.

I don't know if I'm blind, but how do I get the information about the baseline (and therefore the heading) out into a solution file/serial-stream?
And how do I get the information with rtkrcv or in post with rtkpost/rnx2rtkp?

okay, I was blind.
The E/N/U-Baseline Solution outputs the baseline in meters in all 3 dimensions (east, north, up).
With this information, it is easy to calculate the heading of the baseline (with trigonometry in right-angle triangle).
