Abstract:	As part of the Joint Precision Approach and Landing System program, the U.S. Navy has developed and demonstrated the use of a shipboard relative Global Positioning System to perform automatic precision approach and landings aboard an aircraft carrier. Shore based testing began in June 2000 and a new test bed was developed in October 2000. Shore and ship testing commenced again in January 2001 culminating with 10 fully automatic approaches to touchdown aboard the USS Theodore Roosevelt in April 2001. This paper presents a summary of the guidance and control algorithm design with emphasis on key design elements such as time synchronization, inertial blending, ship motion stabilization, deck motion compensation, outer loop control law optimization, control path limiters, and safety features. An evaluation of the guidance and control performance is presented using data from shore based and ship based flight tests.
