US 2015/0088345 A1 · SYSTEM AND METHOD FOR DETERMINING A QUALITY VALUE OF A LOCATION ESTIMATION OF EQUIPMENT

Abstract

A system is provided for determining a quality of a location estimation of a powered system at a location. The system includes a first sensor configured to measure a first parameter of the powered system at the location. The system further includes a second sensor configured to measure a second parameter of the powered system at the location. The system further includes a second controller configured to determine the location estimation of the powered system and the quality of the location estimation, based upon a first location of the powered system based on the first parameter, and a second location of the powered system based on the second parameter of the powered system. A method is also provided for determining a quality of a location estimation of a powered system at a location.
