Dear Bernd,

How can we mix gyro data with GPS to get better location?
Vehicle Locomotive, Can get wheel tick.
What can additional sensors be?

additionally to the comments you've got so far:
I think you should at least have an additional gyro sensor which gives
you some movement data to combine with what you've got from the GPS.
Also if you have other sensors in your vehicle - use them.
You did not mention which kind of vehicle and what you are doing with it
- but if you are not 100% sure that you'll always have good gps
reception (or that you are not close to chinese pig farms with fake gps
transmitters), you *will* have to use additional sensors.
