  • Two-frequency glide-path station for the standardized instrument-landing system ILS
    Patent number: 4599621
    Abstract: To monitor the course signals radiated by the two-frequency glide-path station with respect to course line and course width, and to monitor the clearance signal, the signals radiated by the antennas (A1, A2, A3) and a signal extracted directly from the transmitter (1) are so combined (5, 6, 7) that the clearance signal (CL), the sideband signal (SBO), and the carrier and sideband signal are obtained. These signals are evaluated (8) for monitoring purposes in a manner known per se.
