A method for onboard measurement of a deviation in orientation of an object from a desired orientation of the object. The method including: transmitting a polarized RF signal from a reference source, with a predetermined polarization plane; receiving the signal at a pair of polarized RF sensor cavities positioned symmetrical on the object with respect to the predetermined polarization plane; analyzing an output of the pair of polarized RF sensor cavities resulting from the received signal; and determining the deviation in orientation of the object relative to the predetermined plane based on the analysis. The method can further include controlling the object based on the determined deviation in orientation.
