Abstract

Abstract: Distributed simulations play an important role in complex space safety related examinations. Realizing an associated system-of-systems solution with as less software adaptation development effort as possible represents a key challenge in this context. The paper presents a microservice-based approach, considering possibilities of the new Simulation Interoperability Standards Organization (SISO) standard Space Reference Federate Object Model. Different High-Level Architecture (HLA) compliant solutions are conversed, ranging from usage of the HLA evolved standard's web service application programming interface (API) over the implementation of a tightly coupled bridging federate to the exploitation of the future HLA (HLA 4) version's standardized federate protocol. A human-in-the-loop space flight simulator concept use case is presented and discussed.
