VHF-Omnidirectional Range/Instrument Landing System Receiver and Methods of Use

An unmanned aerial system (UAS) comprising:

• an instrument landing system comprising:
• a wideband antenna configured to receive signals in a very high frequency (VHF) band;
• and
• a receiver coupled to the wideband antenna and configured to implement software-defined radio (SDR) functions to analyze the signals for a flight inspection.

A very high frequency (VHF) omnidirectional range (VOR)/instrument landing system (ILS) receiver system comprising:

• a storage device configured to store instructions;
• and
• a processor coupled to the storage device and configured to execute the instructions to:
• obtain flight inspection data;
• perform channel selection logic on the flight inspection data;
• perform channel control logic on the flight inspection data;
• record raw in-phase/quadrature (IQ) data;
• separate the flight inspection data into very high frequency omnidirectional range (VOR) data, localizer (LOC) data, and glide slope (GS) data;
• process the VOR data in a first thread to obtain processed VOR data;
• process the LOC data simultaneously in a second thread to obtain processed LOC data;
• and
• process the GS data in a third thread to obtain processed GS data.
