GNSS Network Software is an advanced server-based software solution package to control and manage regional and nationwide GNSS CORS and RTK networks. CPS is the result of years of scientific development and technical qualification. With optimised analysis of GNSS positioning errors such as ionospheric, tropospheric, orbit and multipath errors, CPS computes and outputs high quality RTK corrections from single-base up to virtual network base solution. Supporting direct TCP/IP and NTRIP protocols as well as embedded users management, CPS is the solution to deliver local to large-scale reliable CORS and RTK network services.
