Base station self-calibration method

The invention discloses a base station self-calibration method, which comprises the following steps: S1, dividing a positioning area with S base stations Ps with normal communication conditions insideinto M sub-coordinate systems, and setting the number of the sub-coordinate systems as Scoordi (i is greater than or equal to 1 and less than or equal to M); S2, establishing an overall coordinate system Fcoord for constructing base station coordinates of indoor positioning; S3, setting at least two auxiliary base stations in the sub-coordinate system Scoordi (i is greater than or equal to 1 andless than or equal to M), wherein the auxiliary base stations are base stations under known Fcoord coordinates; S4, performing Scoordi self-calibration, and performing distance measurement on the basestations Ps in every two Scoordi (i is greater than or equal to 1 and less than or equal to M) to calculate coordinates of the base stations in the Scoordi (i is greater than or equal to 1 and less than or equal to M); and S5,
