Abstract
(EN)
The present invention relates to a method and apparatus for distributing and generating GNSS positioning correcting data, and suggests a method for distributing or providing virtual RTK base station positioning correcting data to a server or terminal device via a network, the method comprising: dividing a service area in units of virtual cells and positioning a virtual RTK base station in a virtual cell; on the basis of the division and the positioning, calculating, through collective interpolation, positioning correcting data of the virtual RTK base station by using positioning correcting data of an actual RTK base station, which is collected in the service area; and encoding the positioning correcting data as a virtual cell RTK frame. The present invention can differentiate or adaptively differentiate RTK base station data by using a virtual cell map on which virtual cell selection information is displayed, thereby improving the economic efficiency in network costs and achieving optimization of positioning correcting data.

La présente invention concerne un procédé et un appareil de distribution et de génération de données de correction de positionnement GNSS, et concerne un procédé de distribution ou de fourniture de données de correction de positionnement de station de base RTK virtuelle à un serveur ou à un dispositif terminal par l'intermédiaire d'un réseau, le procédé consistant : à diviser une zone de service en des unités de cellules virtuelles et à positionner une station de base RTK virtuelle dans une cellule virtuelle ; en fonction de la division et du positionnement, à calculer, par interpolation collective, des données de correction de positionnement de la station de base RTK virtuelle à l'aide de données de correction de positionnement d'une station de base RTK réelle, collectées dans la zone de service ; et à coder les données de correction de positionnement en tant que trame RTK de cellule virtuelle. La présente invention peut différencier ou différencier de manière adaptative des données de station de base RTK à l'aide d'une carte à cellules virtuelles sur laquelle des informations de sélection de cellules virtuelles sont affichées, ce qui permet d'améliorer l'efficacité économique des coûts de réseau et d'obtenir une optimisation des données de correction de positionnement.
