we are trying to use the OpenRTK330LI as a GPS Reference in a test car.
GPS Localisation seems to work fine and we are also able to see accellerometer-values through the interface but still we still get this.
I've read in this post "INS initializaiton requires few seconds of straight motion with speed > 4 m/s.".
We tried that several times, driving the car in a straight line at several different speeds for several hundred meters and also driving around the city but INS wont activate.
Can you give us advice on how to get INS working?
