摘要： A method for switching a base station, a mower and a multi-base station working system are provided. The method includes: obtaining, when the number of first common-view satellites between the mower and a first base station is less than a first threshold, the number of second common-view satellites between the mower and a second base station; when the number of the first common-view satellites is less than a second threshold and the number of the second common-view satellites is greater than the second threshold, obtaining the first trajectory of the mower based on the first base station and the second trajectory of the mower based on the second base station; determining, based on the first and second trajectories, a coordinate transformation matrix; and switching from the first base station to the second base station based on the coordinate transformation matrix, the second threshold being less than the first threshold.

摘要： A method for recommending an installation position of a base station, a storage medium, a mower, and a mobile electronic device are provided. The method acquires satellite observation data at a plurality of sampling points along a boundary of a target map; determining target sampling points satisfying a preset condition according to satellite observation data at each sampling point; determining common satellite observation frequency bands according to satellite observation data at the target sampling points; determining the number of the common satellite observation frequency bands at each sampling point according to the common satellite observation frequency bands and the satellite observation data at each sampling point; and determining recommendation information of the installation position of the base station according to the number of the common satellite observation frequency bands at each sampling point.
