Electric power infrastructure monitoring system based on satellite positioning

The invention discloses an electric power infrastructure monitoring system based on satellite positioning, and the system employs a first satellite positioning module in a tower footing monitoring data collection module to collect the positioning information of each tower footing. Meanwhile, a second satellite positioning module in a sag monitoring data acquisition module assembled on the power transmission cable acquires positioning information of the power transmission cable, and then a data processing module is used for determining the sag of the power transmission cable according to the positioning information acquired by the two satellite positioning modules in combination with a tower footing displacement judgment algorithm and a catenary sag calculation algorithm. The tower foundation monitoring result of the power transmission tower and the sag monitoring result of the power transmission line are determined, a traditional processing mode that a theodolite and a total station measuring instrument are u
