An optimal ambiguity resolution technique for attitude determination

Integer ambiguity resolution is a crucial component of attitude determination. To ensure that the integer ambiguity resolution process is optimised, all information available should be used in a suitable manner. This information not only provides more rapid ambiguity resolution, but also provides confidence that correct resolution has been achieved. This paper describes a processing procedure which integrates all information about the antenna array with the measurements obtained at each antenna. A sample data set is given which demonstrates that instantaneous integer ambiguity resolution is possible, and that the technique is robust to ensure that measurement biases do not degrade the result
