Abstract:	GPS-RTK enables position accuracy to be improved up to within several centimeters. But it needs much data for corrections, compact-RTK was introduced for GPS-RTK using low-rate data-link. But temporal decorrelation error becomes larger because of low-rate updating corrections in compact-RTK. So a scheduling corrections technique was introduced to reduce the temporal decorrelation error, but there was not a systematic method to design this scheduling technique. In this paper, we discussed some design values for compact-RTK and proposed a new approach to design broadcasting scheduling for corrections with threshold of latency error, the number of satellites in a correction message and so on. We also presented the results of the experiments and simulations to verify that our suggested approach is an effective way to design GPS-RTK scheduling system. We hope that out study will be a great help in designing scheduling compact-RTK corrections algorithm to reduce temporal decorrelation error.
