The reference station is equipped with single-unit serials controlled by a switch from a control unit. They are linked with a transmission/reception change-over switch coupled to a conventional transponder. The aerials are arranged on a circle with a dia. 10-50 times the signal wave length and are linked in turn to the transponder. The evaluation of the average of the signals received averages at the same time all errors. In another version, all aerials are connected up together. They are then linked to transmission or reception by a phase shifter and a power divider.
