Real-time RTK messages for permanent reference station applications standardized by RTCM

摘要

Within RTCM SC104 a working group is developing a standardized method to transfer network RTK information from a processing center to a rover operating in the field. The proposed interface is currently under interoperability testing with participation of several vendors. After the release of this standard, network RTK will be completely interoperable for the first time. Then, networking software developed by different vendors can produce identical output data streams from identical input data. Rovers in the field can operate optimally and their performance is no longer dependent on the actual networking software. The rover receives information about the distribution of reference stations and optimization can be performed in real-time by the rover system. According to the Master-Auxiliary Concept, not only the original raw observations for the Master Station are sent to the rover but also correction differences of the Auxiliary Stations. The rover system can decide to use or to neglect the network RTK information depending on its own firmware algorithm performance.
