The present invention discloses a location augmentation system of multi-network integration supporting multi-type location terminals. The location augmentation system comprises one or more satellite positioning reference stations, a selective access CORS system, an application server and user terminals with different types. The application server is configured to request the output of original data to the CORS system or the satellite positioning reference stations thereof and calculate corresponding difference correction data in real time according to service applied by user terminals with different types. When the user terminals are not located in the service area of the CORS network, satellite positioning reference stations of the CORS system are additionally arranged at the exterior of the CORS network so that the user terminals may send requests to application server and perform high precision positioning through adoption of resources of the satellite positioning reference stations; and when the user terminals are located in the service area of the CORS network, the user terminals may communicate with the application server and perform high precision positioning through adoption of the resources of the CORS system. The location augmentation method of multi-network integration supporting multi-type location terminals is able to support multi-type user terminals and has a difference positioning capability with high precision.
