1. A positioning system for use with a mobile machine, comprising: a first sensor configured to generate a first signal indicative of a pose of the mobile machine; a second sensor configured to generate a second signal indicative of a parameter of the mobile machine; and a controller in communication with the first and second sensors, the controller configured to: generate a measured pose of the mobile machine based on the first signal; generate an estimated pose of the mobile machine based on the second signal; determine uncertainty values associated with each of the measured and estimated poses; determine an overlap of the uncertainty values; selectively adjust the measured pose based on the overlap; and determine a pose solution based on the estimated pose and adjustment of the measured pose.
