Salute!
Good poop, Slatye. If the device has a good GPS lock and decent filters, then it can do a lot for the local level presentation. Just look back a half a century to the doppler damped inertial mode we had in the A-7. Just having "truth" of movement across the Earth without actual position data helped the platforms we used in those days. By late 70's when I got to the Viper we didn't care bout all the gimbals and such and started using "wander angles" and such, but those did depend on good accelerometers and gyro sensors. The age of strapdown systems had begun!
There's a commercial app for the iPad that is alleged to be a virtual HUD. Anybody try that sucker?
