using amplitude comparison of signals transmitted sequentially from antennas or antenna systems having differently-oriented overlapping directivity characteristics, e.g. equi-signal A-N type

Introduced: September 1968

Title

Titles differ between systems:

IPC: using amplitude comparison of signals transmitted sequentially from antennas or antenna systems having differently-oriented overlapping directivity-characteristics, e.g. equi-signal A-N type

CPC: using amplitude comparison of signals transmitted sequentially from antennas or antenna systems having differently-oriented overlapping directivity characteristics, e.g. equi-signal A-N type

Full Title

Full titles differ between systems:

IPC:

Beacons or beacon systems transmitting signals having a characteristic or characteristics capable of being detected by non-directional receivers and defining directions, positions, or position lines fixed relatively to the beacon transmitters; Receivers co-operating therewith > using radio waves > Systems for determining direction or position line > using amplitude comparison of signals transmitted sequentially from antennas or antenna systems having differently-oriented overlapping directivity-characteristics, e.g. equi-signal A-N type

CPC:

Beacons or beacon systems transmitting signals having a characteristic or characteristics capable of being detected by non-directional receivers and defining directions, positions, or position lines fixed relatively to the beacon transmitters; Receivers co-operating therewith (position fixing by co-ordinating a plurality of determinations of direction or position lines G01S5/00) > using radio waves (G01S19/00 takes precedence) > Systems for determining direction or position line > using amplitude comparison of signals transmitted sequentially from antennas or antenna systems having differently-oriented overlapping directivity characteristics, e.g. equi-signal A-N type

IPC and CPC are identically structured here. All 1 subcodes exist in both systems.
