System and method for ground navigation
First Claim
1. A navigation system for use on an aircraft for determining a heading, velocity, and/or position of the aircraft, comprising:
- a first radar antenna for mounting to a first wing of the aircraft and configured to receive radar returns;
a second radar antenna for mounting to a second wing of the aircraft and configured to receive radar returns, the first wing and second wing extending from opposite sides of the aircraft; and
processing electronics configured to determine a velocity of the first and second wings based on the radar returns, the processing electronics calculating the heading, velocity, and/or position of the aircraft based on the determined wing velocities.

Abstract
A method for determining a heading, velocity, and/or position of an aircraft includes receiving a first radar return at a radar antenna for mounting to a first wing of the aircraft and receiving a second radar return at a radar antenna mounted to a second wing of the aircraft where the first wing and the second wing extend from opposite sides of the aircraft. The method also includes determining a velocity of each wing based on the radar returns using processing electronics and calculating the heading, velocity, and/or position of the aircraft based on the determined wing velocities using the processing electronics.
