摘要
A method for calibration of navigation aids for aviation is described. The method comprises recording from aircraft of radio signals transmitted from such navigation aids and comparison with position reports from one or more alternative reference systems. The aircraft's primary equipment (I) is calibrated continuously with parallel-running separate high-precision digital equipment (II) which from the intermediate frequency (IF) signal level (6) exclusively employs digital signal processing with an accuracy of at least 16 bits.
