Method of resolving relative positioning by means of triple-frequency data

The invention discloses a method of resolving relative positioning by means of triple-frequency data. The method comprises the following steps: obtaining known information of a site, triple-frequency observation data of a reference station and triple-frequency observation data of a moving station, and calculating the position of a satellite; conducting combination by means of the known information of the site, the triple-frequency observation data of the reference station and the triple-frequency observation data of the moving station, establishing a super-wide lane combination observation value and a wide lane combination observation value, and then resolving the value of super-wide lane fuzziness and the value of wide lane fuzziness through a plurality of epochs; resolving the fuzziness of all frequencies by combining the super-wide lane combination observation value and the wide lane combination observation value that are fixed in fuzziness with a Geometric-free observation value; and establishing and resolving fuzziness of an observation value of a weak ionosphere according to multifrequency observation values with fixed fuzziness. According to the method of resolving relative positioning by means of triple-frequency data, relative positioning resolving is conducted by means of triple-frequency data, the fuzziness is quick to fix, and a relative positioning base line is longer.
