Problems solved by technology

[0004] However, the existing physical reference stations must be set up on known coordinates, which limits the flexibility of the dedicated network for networking
Moreover, professional personnel are required to carry out manual maintenance on it, and the cost is relatively high.

Abstract

The invention relates to the technical field of satellite positioning and navigation, and particularly relates to a networking method based on phase difference, device and a differential positioning system. The networking method based on phase difference provided in the invention comprises steps: based on differential correction data, the location information of a mobile base station in a stable state is obtained; according to the location information of the mobile base station, the distance between the mobile base station and the networking is calculated; and when the distance between the mobile base station and any networking does not exceed a preset distance, the mobile base station is added to the networking. The scheme provided in the invention can enable the networking to be elastically telescopic, a more flexible networking ability is further realized, and the networking cost is reduced.

Description

technical field [0001] The present invention relates to the technical field of satellite positioning and navigation, in particular, the present invention relates to a phase difference-based networking method, system and device. Background technique [0002] Plant protection drones have very high requirements for flight routes. If precise spraying cannot be achieved, not only will the effect of preventing heavy spraying and missing spraying be achieved, but it may even cause phytotoxicity. Due to the deviation of GPS positioning, traditional plant protection drones will drop height and fly straight, and often have problems such as heavy spraying and missed spraying. How to achieve precise spraying has always been a technical problem in the industry. [0003] At present, the use of network RTK (Real-time kinematic, carrier phase difference) technology for precise positioning has become one of the development hotspots, which relies on CORS (Continuously Operating Reference Stat...
