Abstract:	Competent munitions are key to improving weapons effectiveness, reducing collateral damage and reducing supply requirements for improved force mobility in the future battlefield. Advanced Spinning-Vehicle Navigation (ASVN) is a suite of technologies developed by Rockwell Collins, Inc. to provide cost-effective GPS aiding to rotating munitions operating in a hostile RF environment. This paper describes some of the elements of the ASVN technology suite and some of there potential applications. Also described is the first demonstration of ASVN GPS Roll-Angle Determination (GRAD) on a mechanically-rotating test fixture performed by Rockwell Collins, in collaboration with Alliant Techsystems Inc. (ATK). The paper will also discuss Interference-Aided rapidly rotating vehicles. ASVN utilizes the amplitude and phase modulation of the GPS signals, received by an antenna on a spinning vehicle, to track rotation. Rockwell Collins, Inc. and Alliant Techsystems Inc. (ATK) have recently collaborated to demonstrate ASVN GPS Roll- Angle Determination with a rapidly-spinning antenna. For the first time ASVN has been demonstrated on a mechanically-spinning fixture. ASVN interference mitigation techniques permit GPSaiding under conditions of interference or jamming. The technologies of Interference-Aided Navigation and Temporal Beam Forming can be utilized together for costeffective interference reduction. We will show how an interfering signal may be exploited to actually improve Navigation and Temporal Beam Forming which are aspects of ASVN technology that enable low-cost performance enhancement under conditions of interference or jamming.
