1. A positioning method, comprising:

  • using a differential global positioning system to calculate a double difference of a satellite distance in connection with a reference station and a receiver station;

    calculating a baseline vector pointing from the reference station to the receiver station according to the double difference of satellite distance and cosine law;

    using the baseline vector and a position of the reference station to calculate a position of the receiver station;

    obtaining a plurality of correction coefficients according to the position of the reference station, the position of the receiver station, and a current time; and

    correcting the position of the receiver station according to the correction coefficients and a length of the baseline vector.
