A navigation and positioning performance evaluation scheme for marine application scenar-ios was proposed,which solved the problems of high cost of setting up offshore CORS stations and high navigation time costs,and provided a new solution for testing the positioning performance of off-shore CORS systems.By establishing a land network to simulate the networking conditions of coastal areas,the initialization time,fixation rate,and positioning accuracy at different baseline distances were tested.The results showed that when the baseline distance was within 50 km,the initialization time was short,the fixation rate was high,and the positioning accuracy was relatively good.When the baseline distance exceeded 50 km,the positioning accuracy gradually decreased,and the posi-tioning performance was similar to PPP positioning performance.
