Abstract

The present invention relates to a state identification method, device, equipment and storage medium. The method includes: calculating the satellite attribute information corresponding to each epoch and the position information of the target object according to the observation data of at least two epochs; and then according to the satellite attribute information and the position information of the target object, calculating a plurality of target objects to The radial distance change rate of the satellite; finally, the operating state of the target object, the first preset observation model and the second preset observation model can be identified according to the radial distance change rate, the first preset observation model, and the second preset observation model. The model is used to calculate the observation residuals of each satellite relative to the target object. The state identification method proposed in this application is simple in calculation and high in sensitivity.

Description

technical field [0001] The present invention relates to the technical field of global navigation satellite system (GNSS) positioning, and in particular, to a state identification method, device, computer equipment and storage medium. Background technique [0002] With the rapid development of global navigation satellite system (Global Navigation Satellite System, GNSS) positioning technology in various application fields, the use of GNSS positioning technology can realize the speed measurement, position coordinate positioning, motion status recognition and other applications of target objects. Among them, the recognition technology of the moving state of the target object is an important technology, especially the recognition of the static state of the target object has very important value. [0003] At present, the identification of the stationary state of the target object mainly relies on the speed information calculated by GNSS positioning, and when the calculated speed ...
