Service-oriented SMP2 modeling and simulation for GNSS

Abstract

â??We propose a service-oriented modeling and 
 simulation (M&S) method based on simulation model 
 portability 2 (SMP2) to simulate the performance of the 
 Global Navigation Satellite System (GNSS). The proposed 
 method can be utilized to construct large complex 
 simulation systems, such as GNSS, to determine the 
 reusability, composability, and interoperability of 
 heterogeneous simulation resources. A service-oriented 
 SMP2 M&S framework with its conceptual framework, 
 system architecture, and system engineering process is first 
 introduced. The development and composition of the SMP2 
 model as well as the schedule method are then discussed in 
 detail. Lastly, a service-oriented SMP2 M&S environment is 
 designed and implemented, and the regional dilution of 
 precision performance of the GALILEO Navigation Satellite 
 System in China is analyzed based on the architecture and 
 method.

A Parallel Simulation Method for Performance Analysis of GNSS

“…In M&S specification field, compared to other M&S specifications, Simulation Model Portability Standard 2 (SMP2) [2,3] which is advanced by Europe Space Office in 2004 has superiority in domain independence, platform independence, simulation model framework description, and the overall process supporting for simulation development and application, which can promote modeling friendliness, simulation high-efficiency, integration convenience and model reusability [4]. In system development paradigm field, Service-oriented architecture (SOA), which integrates the existing service to achieve the required functionalities to build the application, is an ideal distributed software development paradigm [5].…”
