Claim 17:
18. A method of determining the relative positions of components of a munitions system, the munitions system comprising a first component and at least one second component, the method comprising:
monitoring the output of a resonant circuit provided on the first component, the resonant circuit having a resonant frequency;
detecting a change in the output due to a change in the resonant frequency caused by a change in the relative positions of the first component and the at least one second component;
using the detected change to determine that the at least one second component has moved relative to the first component; and
providing a signal having an oscillation frequency to a resonant circuit, wherein the resonant frequency of the resonant circuit is closer to the oscillation frequency of the signal when the first component is distant from the at least one second component than when the first component is within close proximity to the at least one second component.
