Data source automatic switching software for servo system of shipboard satellite communication station design and implementation

When the shipboard satellite communication station captures and tracks the satellite, it needs to use the data source to provide support. In the current servo monitoring software, before capturing the satellite, it needs to manually select three data sources. After the onboard satellite communication station enters the self-tracking state, if the data source needs to be switched, it can only be switched manually in the servo monitoring software panel. If the data source is invalid or inaccurate, it is necessary to switch the data source in time to ensure the stable tracking of the antenna.
