One problem with conventional GPS receivers in car navigation applications is that they tend too loose satelite fix when trees or buildings block their view. This seems to happen mostly on moments that you depend on the navigation system, for example in cities.

The solution to this problem comes with this receiver. It combines the normal GPS functionality with a so-called dead reckoning positioning system. This uses a solid state gyro to calculate the heading and combines this with the speed signal of the car. Together this results in a differential position, which is used to continue navigation until satelites can be reaquired.
