Abstract
(EN) A method, an apparatus and a device for receiving satellite navigation differential data, and a storage medium. Said method comprises: receiving an externally inputted approximate location, acquiring grid information broadcast by a broadcast station, and determining whether the approximate location is within the coverage range of the current frequency point in the grid information (S10); if not, determining whether there is a target frequency point, covering the approximate location, in an adjacent broadcast station of the broadcast station (S20); if so, taking the target frequency point as a working frequency point, and switching to the working frequency point and monitoring the operation state of the working frequency point (S30); if the operation state is normal, determining, according to the approximate location and the grid information of the working frequency point, whether a receiving end is in an optimal grid (S40); and if not, switching to the optimal grid, and receiving differential data of the optimal grid, so as to perform positioning according to the differential data (S50).
(FR) L'invention concerne un procédé, un appareil et un dispositif de réception de données différentielles de navigation par satellite, et un support d'information. Ledit procédé consiste à : recevoir un emplacement approximatif entré de manière externe, acquérir des informations de grille diffusées par une station de diffusion, et déterminer si l'emplacement approximatif se trouve dans la plage de couverture du point de fréquence courant dans les informations de grille (S10) ; si ce n'est pas le cas, déterminer s'il existe un point de fréquence cible, couvrant l'emplacement approximatif, dans une station de diffusion adjacente de la station de diffusion (S20) ; si c'est le cas, prendre le point de fréquence cible comme point de fréquence de travail, et commuter vers le point de fréquence de travail puis surveiller l'état de fonctionnement du point de fréquence de travail (S30) ; si l'état de fonctionnement est normal, déterminer, conformément à l'emplacement approximatif et aux informations de grille du point de fréquence de travail, si une extrémité de réception est dans une grille optimale (S40) ; et si ce n'est pas le cas, commuter vers la grille optimale, et recevoir des données différentielles de la grille optimale, de manière à effectuer un positionnement conformément aux données différentielles (S50).
(ZH) 一种卫星导航差分数据接收方法、装置、设备和存储介质,该方法包括:接收外部输入的概略位置,获取广播台广播的网格信息,确定概略位置是否在网格信息中当前频点覆盖范围内(S10);若否,则判断广播台的邻近广播台中是否存在覆盖概略位置的目标频点(S20);若是,则将目标频点作为工作频点,切换至工作频点并监测工作频点的运行状态(S30);在运行状态正常时,根据概略位置和工作频点的网格信息判断接收端是否处于最优网格(S40);若否,则切换至最优网格,并接收最优网格的差分数据,以根据差分数据进行定位(S50)。
