Abstract： High precision global navigation satellite system(GNSS) measurement must adopt carrier phase observation value. RTK is a real-time kinmeatic technology based on carrier phase observation value. It can provide three-dimensional positioning results of instrument station in the specified coordinate system in real time. In the RTK operation mode of Beidou navigation satellite system(BDS), the base station transmits its observation values and station coordinate information to the rover station through the data link. However, under the condition of centralized storage, these data are easy to be tampered. If tampering occurs in cadastral survey, forest fire prevention, maritime rescue and other events, it may cause life and economic damage to citizens and national stakeholders. Therefore, it is necessary to identify wrong and forged data to ensure the integrity of Beidou data, and improve the reliability of data by supporting traceability and public verifiability. Blockchain is a distributed ledger system, which is naturally decentralized, publicly verifiable, tamper proof and traceable. In this paper, a new RTK service framework of Beidou satellite navigation system is proposed. The blockchain network is used to record Beidou data, and the public verifiability and non-tamperability of blockchain are used to ensure the integrity and reliability of Beidou data. The rover station is used to monitor the RTCM(Radio Technical Commission for Maritime services) data flow, improve the monthly package annual billing mode, realize the billing by data traffic, make the payment mode more reasonable and refined, and use the Ethereum client to build a private chain for implementation.
