A pair of GPS receivers A and B which are constructed in the form of the receiver antenna combinations with receivers/antenna combinations which have been associated as ground-planes that extend beyond them. They are arranged such that the lower surface of the ground-plane of one receiver is adjacent to an RF absorber sheet, and the bottom of the RF absorber sheet is placed from the top of the second GPS receiver. This structure allows for the mask angle of the GPS receiver B to be matched to the mask angle of the GPS receiver A. When the normal path signal received by GPS receiver A becomes so large that it interferes with the direct signal to an unsatisfactory degree, reception is switched to GPS receiver B which senses only multi-path signals, but which allows the lock of the receiver pair combination to be maintained.
