Determining approximate position of a user machine based on inernet (IP) address

An apparatus for processing positioning information, comprising an acquisition unit, an approximate position determination unit, and a correction data determination unit, wherein

• the acquisition unit is configured to obtain an Internet Protocol (IP) address of a user machine connected to a Network real-time kinematic (RTK) server in real time;
• the approximate position determination unit is configured to determine an approximate position of the user machine according to the IP address obtained;
• and
• the correction data determination unit is configured to determine, according to the approximate position of the user machine, a correction data of a virtual reference station to be sent to the user machine, wherein before obtaining the IP address of the user machine connected to the Network RTK server, the method further comprises:
• determining whether the user machine sends an actual position to the network RTK server;
• when the user machine sends the actual position to the RTK server, determining, according to the actual position, a grid where the user machine is located;
• and determining the correction data of the virtual reference station according to the grid where the user machine is located, according to the actual position;
• and
• when the user machine does not send the actual position to the RTK server, triggering the process of obtaining the IP address of the user machine connected to the Network RTK server.
