Problems solved by technology

[0003] At present, when most enterprises use GNSS, they usually directly use the chips provided by GNSS chip manufacturers, but enterprises are not sure whether the GNSS chips provided by the selected manufacturers are stable.
Judging whether the GNSS chip is stable is mainly to determine the stability of the observed data of the GNSS chip, but there is no method for determining the stability of the observed data of the GNSS chip in the prior art

Abstract

The invention provides an observation data stability determination method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining observation data and observation time corresponding to satellite signal data in a plurality of GNSS chips, and enabling the plurality of GNSS chips to receive the satellite signal data through the same antenna; calculating an absolute value of a difference value of observation data belonging to the same observation time in each group of chips to obtain a first numerical value; each group of chips comprises two GNSS (Global Navigation Satellite System) chips; for each group of chips, calculating an absolute value of a difference value between the first value of the observation time of the current moment and the first value of the observation time of the previous moment to obtain a second value; and determining the stability of the observation data of each group of chips according to the change amplitude of the second numerical value corresponding to each group of chips in time. Through the mode of the invention, the stability of the observation data of the GNSS chip can be determined.

Description

technical field [0001] The invention relates to the technical field of satellite navigation, in particular to a method, device, electronic equipment and storage medium for determining the stability of observation data. Background technique [0002] With the development of science and technology, GNSS (Global Navigation Satellite System, global satellite navigation system) is also applied in various fields. [0003] At present, when most enterprises use GNSS, they usually directly use the chips provided by GNSS chip manufacturers, but enterprises cannot be sure whether the GNSS chips provided by the selected manufacturers are stable. Judging whether the GNSS chip is stable is mainly to determine the stability of the observation data of the GNSS chip. However, there is no method for determining the stability of the observation data of the GNSS chip in the prior art. Contents of the invention [0004] In view of this, the purpose of this application is to provide a method, d...
