With the growth of mass-market demand for high-precision positioning, it is desperate to require the technological innovation of low-cost precision positioning technology. At present, GBAS alone has problems of limited coverage, dependence on public network communication, poor integrity, and high terminal power consumption, while SBAS alone has some problems of low positioning accuracy, which affects the construction of power transmission channel for disaster prevention and mitigation. Therefore, relying on the integration service of GBAS and SBAS for the electric power Beidou precision service system, an architecture of power temporal and spatial cloud service center that meets the requirements of power system is proposed, which would provide solutions in power infrastructure monitoring scenarios.
