DIRECTIONAL AND TIMING CONTROL CIRCUIT FOR WATER PUMP

An inertial navigation system and method are provided. The system includes a plurality of three-axis sensors and a controller operatively coupled to the plurality of three-axis sensors. The method includes the controller: receiving an output from each of a plurality of three-axis sensors; determining a plurality of solutions, each of the plurality of solutions based on the output of one of the plurality of three-axis sensors; applying a Gaussian curve to the plurality of solutions; weighting each of the plurality of solutions based on a position on the Gaussian curve of each of the plurality of solutions, thereby determining a plurality of weighted solutions; calculating a roll, a pitch, and a heading of a device based on the plurality of weighted solutions; and iteratively repeating the receiving, determining, applying, weighting, and calculating.
