1. A method for testing a navigation system including the steps of:
- a) travelling a test path from a beginning geographic location to a destination geographic location;
b) receiving input signals from at least one position-determining device while travelling said test path;
c) storing said input signals while travelling said test path;
d) utilizing said signals stored in said step c) as a simulated trip to test the navigation system;
e) monitoring an output of said navigation system in response to said step d); and
f) comparing said output to said test path to verify the operation of the navigation system.

Abstract
A navigation simulator and recorder includes a computer and several position and attitude determining devices installed in a vehicle driven along a test route. The data from the position and attitude determining devices is stored in the computer while the vehicle is driven along the test route. The recorded data from the test drive is subsequently utilized to test a navigation system. The output of the navigation system under test is monitored to determine its response to the real time recorded data.

12. A system for testing a navigation system including:
-
at least one position-determining device generating position signals while traveling a test route; a data storage device for storing said position signals generated during said test route; a simulator for sending simulated input signals to the navigation system based upon said stored position signals; means for monitoring an output of the navigation system; and means for comparing the output to the test path to verify the operation of the navigation system. - View Dependent Claims (13, 14, 15, 16, 17)
