Research on Key Technology of Power Spatiotemporal Big Data with Beidou Communication

With the rapid development of communication technology, the demand for remote transmission of massive data is getting higher and higher. The development of the BDS will greatly promote the high-speed transmission of information. Build a unified space-time information support framework based on Beidou, and make key breakthroughs in the aspects of timing, navigation, and short message communication. Globally measured positioning accuracy is better than 2.5 meters in the horizontal direction, and 5.0 meters in the vertical direction, velocity measurement accuracy is better than 0.2 meters/s, timing accuracy is better than 20 nanoseconds, and system availability is improved to 99%. This paper takes optical radio frequency (RoF) and Beidou blockchain as the core to research key technologies of power big data, which will provide strong technical support for better application in the analysis and transmission of power big data. The research results can be applied to many fields, which have important academic significance and practical application value.
