Abstract

GPS has been used successfully to determine attitude for a moving platform. A direct calculation method of real-time attitude determination using three-antenna system for the moving platform is described. Since real-time integer ambiguity resolution for baseline vectors is a key process for a high accuracy real-time attitude determination, the ambiguity resolution method and validation test procedure epoch-by-epoch are proposed based on the special property of the three-antenna system. Simulation study results are presented in this contribution showing that better than one degree accuracy of the platform attitude can be achieved using the proposed method.
