First Galileo only based navigation solution announced.

After extensive testing the four Galileo IOV (In-Orbit-Validation) satellites have been used for an autonomous navigation solution. Even so the results are not very impressing there is quite some complex procedure behind. It does not only involve the simple positioning calculation, but also the whole process chain of orbit determination and bias determinations for the satellites.
