The IGS technology of GPS has made such great achievements and contributions, so in September 1999, VLBI and SLR stations in various countries decided to organize corresponding IVS and IVRS similar to IGS. DORIS in France and PRARE in Germany are also considering establishing international organizations with similar models. Strive to organize such spatial geodetic observation systems, improve efficiency, accuracy, and reliability.
In terms of regional GPS continuous operation station networks and integrated service systems, developed countries have also done a lot of work in this area and made progress. A GPS "Continuous Operating Reference Station" (CORS) system has been deployed in the United States. It is managed by the United States Geodetic Survey (NGS), and the current goal of the system is to (1) make it more convenient for all users across the United States to use it to achieve centimeter level positioning and navigation; (2) Promote users to utilize CORS to develop GIS; (3) Monitoring crustal deformation; ④ Determine the distribution of water vapor in the atmosphere; ⑤ Monitor the concentration and distribution of free electrons in the ionosphere.
As of September 1999, CORS had 156 stations, and NGS in the United States announced that in order to strengthen the CORS system, from now on, it will increase the speed of 3 stations per month to improve the spatial coverage of the system. In addition, CORS data and information include received pseudo range and phase information, station coordinates, station movement rate vectors, GPS satellite gas, meteorological data around the station, etc. Users can easily download them through information networks such as the Internet.
The "Continuous Operating GPS Reference Station" (COGPS) system established in the UK has functions and objectives similar to the CORS mentioned above, but in combination with the local situation in the UK, there is also an additional task to monitor relative and absolute sea level changes around the three islands of England. COGPS in the UK is jointly managed by the Surveying and Mapping Bureau, the Environmental Protection Agency, the Meteorological Bureau, the Department of Agriculture, and the Marine Laboratory. At present, there are nearly 30 GPS continuous operation stations. The future plan is to expand the COGPS system and establish a center, whose main task is to transmit, provide, archive, process, and analyze GPS data from each station.
