    Abstract
  • With the rapid development of satellite technology and aerospace industry, ensuring the safety of the operation of space technology systems places higher requirements on the space environment forecast service. Based on the current situation of distributed integration and sharing of data and model resources in space environment information services, this paper applies Web service technology and semantic service combination technology to space environment information services to meet the needs of intelligent and automated generation of space environment forecast products. According to the characteristics of the space environment domain, a method for calculating the semantic similarity in the space environment domain is proposed, and a method based on semantic similarity is used to realize the automatic combination of space environment information services. The validity of service combination technology is verified by taking the generation of ionospheric TEC mapping data as an example, which can provide a reference for the research of remote sharing and automatic combination of resources in space environment.
