Research on Aerial Correction of Compass Error of Automatic Direction Finder
The causes and characteristics of the Automatic Direction Finder (ADF) deviation of helicopters were studied,and a method of automatic radio compass deviation correction in the air based on satellite navigation and positioning technology was proposed.The azimuth angle between the helicopter's combined navigation system and the ground reference point was determined by obtai-ning the helicopter's position data and the ground reference point's position data,and the difference between the value and the display azimuth angle of the radio compass was the radio deviation.This method was more adaptable to the site than conventional methods and effectively solved the problem of being unable to correct the deviation in the field without a dedicated compass site.
