Abstract
A method of compensating a position of an object by using a Global Navigation Satellite System (GNSS) processor is provided. The method includes generating a compensated position associated with a target satellite at a compensation target time based on a pseudo range between the object and the target satellite at the compensation target time, generating a displacement vector of the object based on the compensated position at the compensation target time and a previous position of the object at a previous time that is prior to the compensation target time, determining a weight for the compensated position associated with the target satellite based on a velocity vector at the compensation target time and the displacement vector, and compensating a predicted position of the object according to the weight and the compensated position.
