A technique of automatic bias compensation has been devised to correct errors caused by variations among electronic components in Global Positioning System (GPS) receivers that use the coarse/acquisition (C/A) GPS code. Even though there are large government and commercial markets for such GPS receivers, these errors have not been generally understood. [Alternatively or in addition to the automatic-bias-compensation technique, the errors can be reduced by (1) building GPS receivers from components of higher quality (that is, components that have lower manufacturing tolerances and are less susceptible to aging) and (2) performing more extensive manual adjustments during integration and testing of GPS receivers.]
