Difference between direction finding and positioning

1. Direction finding is a method to determine the orientation of an object or target by measuring the direction angle between the object or target and a reference point. Direction finding generally requires the use of equipment such as direction finder or radar to determine the orientation of an object or target through accurate direction angle measurement. Focus on measuring the direction angle between an object or target and a reference point.

2. Positioning is a method to determine the position of an object or target by measuring the distance or distance difference between the object or target and multiple reference points. Positioning generally requires the use of global positioning system (GPS), Beidou satellite navigation system, ground measuring instruments and other equipment to determine the position of an object or target by measuring and calculating multiple position information. Focus on measuring the distance or distance difference between an object or target and multiple reference points, so as to determine the position of the object or target.
