Abstract

As UAVs and sensor networks become ubiquitous, cost and accuracy will be increasingly traded. We have developed techniques for calibration that consider this problem. Our technique performs a nonlinear optimization through all variables associated with zeroth and first order affects on accuracy of the sensors. The optimization is constrained by the known properties of the magnetic and gravitational fields. A miniature autopilot is presented as an example of the pressing need for automation of calibration.
