Satellite orbit determination method and system

The invention provides a satellite orbit determination method and system, and relates to the technical field of satellite orbit determination, and the method comprises the steps: obtaining a satellite set to be subjected to orbit determination and a distance measurement forwarding station set for orbit measurement; determining a polling rule of each ranging forwarding station in the ranging forwarding station set based on the satellite set, the ranging forwarding station set and a preset constraint condition; based on the polling rule, the target ranging forwarding station is called to carry out ranging on at least one satellite supported by the target ranging forwarding station, and ranging data of each satellite at the corresponding polling time are obtained; and determining an orbit determination result of the target satellite based on all the distance measurement data of the target satellite. According to the method, the ranging forwarding stations are controlled to carry out ranging on at least one satel
