Class Information
Number: 342/396
Name: Communications: directive radio wave systems and devices (e.g., radar, radio navigation) > Directive > Beacon or receiver > With transmisson of bearing or position determinative signals > Iso-phase type > Omega
Description: Subject matter wherein hyperbolic lines of position are determined by measuring the changes in distances from the transmitters by counting radio-frequency wavelengths in space or lanes (iso-phase lines) as a vehicle moves from a known position, the lanes being counted by phase comparison with a stable oscillator aboard the vehicle.
