Various systems benefit from suitable mechanisms and methods for dealing with sensor inaccuracy. For example, various attitude and heading reference system (AHRS) approaches may benefit from systems and methods for providing multiple strapdown solutions. A system can include a plurality of three-axis sensors configured to measure physical quantities (e.g. acceleration, rotational rate), from which can be computed roll, pitch, and heading for a device. The system can also include a controller configured to receive output of the plurality of three-axis sensors as a plurality of inputs, determine a plurality of strapdown solutions each solution of the plurality of solutions based on respective output of the plurality of three-axis sensors, each of which consists of roll, pitch, and possibly heading, weight each output of the plurality of output solutions based on a relation between a given output solution and the other output solutions of the plurality of solutions, and report the roll, pitch, and heading of the device.
