Abstract

The invention provides an error model calibration method, device and equipment and a computer readable storage medium, and relates to the field of maps. The method comprises the following steps of: receiving observation data acquired by calibration equipment, and acquiring satellite data according to the observation data; respectively calibrating a pseudo-range error array and a Doppler error array for at least two terminals in the calibration equipment based on the observation data, the geometric distance of each device in the calibration equipment and the satellite data; wherein the pseudo-range error array describes discrete distribution of pseudo-range measurement errors of the at least two terminals under the carrier-to-noise ratio and the elevation angle of the satellite, and the Doppler error array describes discrete distribution of Doppler measurement errors of the at least two terminals under the carrier-to-noise ratio and the elevation angle of the satellite; and fitting pseudo-range error models of the at least two terminals by using the pseudo-range error array, and fitting Doppler error models of the at least two terminals by using the Doppler error array. According tothe invention, the universality of error model calibration can be improved.

Description

technical field [0001] The present application relates to satellite positioning technology in the field of maps, and in particular to an error model calibration method, device, equipment and computer-readable storage medium. Background technique [0002] Global satellite navigation systems have been widely used in aviation, navigation, communications, personnel tracking, consumer entertainment, surveying and mapping, timing, vehicle monitoring and management, car navigation and information services, and the general trend is to provide high-precision services for real-time applications. Since there is an error between the pseudo-range measurement value and Doppler observation value obtained by the satellite positioning equipment and the real value, before positioning, it is necessary to determine the error model of pseudo-range and Doppler. In related technologies, it is difficult to implement error model calibration in various types of mobile terminals, so that the universal...
