摘要
Disclosed is a star network-based BDS/GPS broadcast network RTK algorithm. All base stations form a triangulation network by using Delaunay triangulation algorithm; and a controllable full-region star network formed by a plurality of star network elements is generated on the basis of the triangulation network. Data of the base stations is obtained in real time and network element calculation is performed to generate a baseline atmospheric error. In addition, on the basis of on a UDP protocol, a server broadcasts a master station observation value, base station coordinates, and the baseline atmospheric error to a user by using the star network as a unit; the user selects, according to an approximate location thereof and the location of the master station, a network element where the user is located; and interpolation is performed on an inter-station single-difference atmospheric error of the baseline formed by the user and the master station, and the obtained atmospheric error is corrected to the master station observation value to perform baseline calculation. The user can also upload approximate coordinates by means of two-way communication and the server broadcasts differential data of the network element where the user is located. In addition, differential data broadcasting by equipment such as ground equipment, an airplane, or a satellite is also supported.
