Abstract:	This paper proposes a low cost navigation and landing system for both General aviation (GA) and Military aircraft. For GA aircraft, the goal is to reduce the number of accidents. It gives military aircraft the capability of landing anywhere in the world with CAT II accuracy, without WAAS/LAAS/ILS or other ground aids. It combines micro-machined silicon inertial sensors with 3D-AIME TM , which uses stored terrain and altimeter data to calibrate the vertical channel of a tactical grade IRS. The calibrated vertical IRS channel has a 1.5 meter accuracy at a decision height of 100 feet. It is extremely reliable, and is unaffected by short term loss of signal due to unintentional interference or jamming. To improve anti-jam capability, an additional 30–40 dB J/S can be achieved using AJ-AIME TM . This is obtained without the loss of integrity associated with the alternative vector processing approach, which optimally combines all measurements in a giant maximum likelihood estimator.
