G01S0001160000 Azimuthal guidance systems, e.g. system for defining aircraft approach path, localiser system 1
G01S0001180000 Elevational guidance systems, e.g. system for defining aircraft glide path 1
G01S0001200000 using a comparison of transit time of synchronised signals transmitted from non-directional aerials or aerial systems spaced apart, i.e. path-difference systems 1
G01S0001220000 the synchronised signals being frequency modulations on carrier waves and the transit times being compared by measuring difference of instantaneous frequencies of received carrier waves 1
G01S0001240000 the synchronised signals being pulses or equivalent modulations on carrier waves and the transit times being compared by measuring the difference in arrival time of a significant part of the modulations 1
G01S0001260000 Systems in which pulses or time-base signals are generated locally at the receiver and brought into predetermined time-relationship with received signals, e.g. pulse duration coincides with time interval between arrival of significant part of modulation of signals received from first and second aerials or aerial systems 1
G01S0001280000 wherein the predetermined time-relationship is maintained automatically 1
G01S0001300000 the synchronised signals being continuous waves or intermittent trains of continuous waves, the intermittency not being for the purpose of determining direction or position line and the transit times being compared by measuring the phase difference 1
G01S0001320000 Systems in which the signals received, with or without amplification, or signals derived therefrom, are compared in phase directly 1
G01S0001340000 Systems in which first and second synchronised signals are transmitted from both aerials or aerial systems and a beat frequency, obtained by heterodyning the first signals with each other is compared in phase with a beat frequency obtained by heterodyning the second signals with each other 1
G01S0001360000 Systems in which a beat frequency, obtained by heterodyning the synchronised signals, is compared in phase with a reference signal having a phase substantially independent of direction 1
G01S0001380000 using comparison of (1) the phase of the envelope of the change of frequency, due to Doppler effect, of the signal transmitted by an aerial moving, or appearing to move, in a cyclic path with (2) the phase of a reference signal, the frequency of this reference signal being synchronised with that of the cyclic movement, or apparent cyclic movement, of the aerial 1
G01S0001400000 the apparent movement of the aerial being produced by cyclic sequential energisation of fixed aerials 1
G01S0001420000 Conical-scan beam beacons transmitting signals which indicate at a mobile receiver any displacement of the receiver from the conical-scan axis, e.g. for "beam-riding" missile control 1
G01S0001440000 Rotating or oscillating beam beacons defining directions in the plane of rotation or oscillation 1
