Abstract
A new method for mobile station positioning applying circular lateration data is proposed. The method is intended for application in close to singular cases, typical in highway environments, to reduce the positioning error. The method is non-iterative and avoids reduction of the original system of equations to linear, being based on processing intersections of circles, instead. In this manner, inconsistencies of the positioning result with the input data are reduced. Implementation of the new algorithm requires modifications in software only. Performance of the method is shown to be statistically better in comparison to the method that reduces the equation system to linear even in general case.
