In this paper the implementation of a digital VOR/ILS precision detector for a calibration receiver of the navigation system in civil aviation has been considered. The implementation of the VOR/ILS precision detector has been done with five TI TMS32010 digital signal processors. Sampling is done using the bandpass sampling theorem directly from the IF of 500 kHz. The VOR/ILS precision detector includes among other things non-coherent AM and FM detectors. A phase difference detector and a modulation depth detector have been developed specially for this application. The VOR/ILS precision detector has been found to work well even in situations where there exists a frequency inaccuracy caused e.g. by Doppler effect.
