The Design and Implementation of GNSS Data Services Based on SOA

【摘要】：The development of network software technology makes data services towards the directions of diversification, real-time, integration and individuation etc. Currently, most GNSS data service centers use file-based data method to distribute, share and transfer data, which is good for storage but not good for data sharing and data using. It is not the direct data waned by GNSS software. The software based on SOA (Service Oriented Architecture) interact with each other by interface, which is independent from hardware platforms, operating systems and programming languages, achieved low coupling sharing of data and functions(services) of the different applications on the network. If the basic GNSS data service center is using SOA architecture to achieve GNSS data and functional services, the current GNSS applications will be greatly expanded. This paper design and briefly achieve the GNSS data services based on SOA architecture, and implement the application of data and functions sharing between different network applications. Practice has proved that the GNSS data services based on SOA conducive to the integration of multi-program, realization of personalized program, and its real-time ability is much better.
