A demo program is provided with the toolbox to show how the toolbox functions may be used to simulate inertial navigation of a great circle path. Functions are provided to generate raw measurements and also to process these measurements. For a New York to Istanbul path, the results of the simulation are:
Since no sensor or initialization errors are modeled here, the original path (produced by GREATCIR) and the inertially-derived path overlay each other. To see what happens when sensor errors are included, visit here.
