METHODS AND SYSTEMS FOR MONITORING MULTIPLE CHANNELS IN A VERY HIGH FREQUENCY OMNI-DIRECTIONAL RANGE RECEIVER

摘要

The present invention relates to methods and systems for time-multiplexing a single VOR receiver to determine bearings from two or more VOR stations and thus determine a relative position of an object such as an aircraft. The invention employs a software-programmable digital signal processor (DSP) to process the VOR signals and control the amplifier stage. The gain control parameters that are used to process the VOR signals are stored for each processed carrier frequency so that the VOR signals may be quickly and releably acquired; thus, enabling the time-multiplexing of the VOR receiver.
