Abstract
A method and apparatus for suppressing weak navigation satellite signals so as to increase the continuity with which the location of the receiver can be determined. In a navigation satellite system having a receiver connected to an antenna or antennas by a shielded cable, a tubular member of magnetic material is placed around the outside of the cable, in close proximity to the receiver, in order to reduce the effect of relatively weak satellite signals that cannot be used, but interfere with the proper use of stronger signals.
