A network RTK anti-ionospheric disturbance positioning method, apparatus,
system, device and storage medium. The method includes: a
server generates, according to
observation data and position information of base stations in a
base station network, ionospheric errors and tropospheric errors of a plurality of baselines, the baseline being formed by connecting two of the base stations; performs modeling based on the ionospheric errors and the tropospheric errors of the plurality of baselines and the position information of the base stations to obtain an atmospheric error model; calculates
differential correction data for a plurality of grid point positions in the
base station network and quality indicators for the plurality of grid point positions according to a
model parameter of the atmospheric error model; determines, according to approximate position information sent by a terminal, a target grid point closest to the approximate position of the terminal from the plurality of grid point positions; and broadcasts
differential correction data and a quality indicator for the target grid point to the terminal; the terminal receives
differential correction data and a quality factor broadcast by a
server, the differential correction data and the quality factor being generated by the
server according to
observation data and position information of base stations and approximate position information uploaded by the terminal; determines an RTK filtering mode according to the received quality factor, the RTK filtering mode including an
ionosphere-free combined filtering mode or a non-combined filtering mode; and performs filtering and calculation, using the determined RTK filtering mode, on
observation data of the terminal and the differential correction data received by the terminal to obtain high-precision position information of the terminal. The apparatus includes a receiving module, a judging module and a positioning module; or the apparatus includes an error module, a modeling module, a calculating module, a matching module and a
broadcasting module. The
system includes a server and a terminal. The device includes a processor and a memory storing
computer program instructions. The computer storage medium includes
computer program instructions stored thereon.
