Abstract
RDSS system is a self-developed navigation and positioning system of China, which provides users with positioning, timing, communication and location reporting services. Due to the aging of RDSS equipment, there is a long-term drift in various types of RDSS devices’ time delays. There is some jump for RDSS positioning accuracy with the change of the out-station beams, which seriously affects the positioning accuracy and service capability of RDSS system. At present, the time delay calibration method is that the device is sent to the equipment verification field to re-measure the time delay, which is cumbersome and takes a long time. The service performance and availability of the RDSS system are greatly degraded. Therefore, a simple, efficient RDSS time delay calibration method becomes an important topic in the Beidou global system. In this paper, the out-station link time delay is got by the differential method of all out-station beams. The experiments were made by Beidou RDSS data, the results showed that the accuracy of the time delay in out-station beams was better than 2.87 ns based on the consistency method in continuous 7-day experiments. The positioning experiments were made based on the original delays and adjusted delays, the mean horizontal positioning accuracy of the RDSS users in Hainan area was increased from 19 m to 2.56 m, with an average increase of 87%. The positioning accuracy achieved in this paper is much better than that in Beidou calibration area of 20 m.
