Scalable Integrated Multi-Mission Support System Simulator Release 3.0

The Scalable Integrated Multi-mission Support System (SIMSS) is a tool that performs a variety of test activities related to spacecraft simulations and ground segment checks.

The GSFC Mission Services Evolution Center (GMSEC) has been advancing new technologies using its architecture to aid missions in the development of control centers, and to enable the interoperability of mission operations center (MOC) components. These new technologies are intended to provide missions with low-cost solutions in implementing their ground systems. SIMSS Version 2.0 was developed to run within the GMSEC architecture as a plug-in component. To accomplish this, SIMSS is integrated with GMSEC application programming interface (API) 3.0 li brar ies, which allows SIMSS to successfully operate in the GMSEC environment and communicate with other components using GMSEC messages that are transmitted over the GMSEC messaging middleware interface bus.

This innovation (SIMSS Release 3.0) provides a Generic Simulator module, which supports the use of an XTCEbased project database (PDB) from which telemetry data is generated, and then is published onto the GMSEC message bus.

SIMSS is a distributed, componentbased, plug-and-play client-server system useful for performing real-time monitoring and communications testing. SIMSS runs on one or more workstations and is designed to be user-configurable or to use predefined configurations for routine operations. SIMSS consists of more than 100 modules that can be configured to create, receive, process, and/or transmit data. The SIMSS/GMSEC innovation is intended to provide missions with a low-cost solution for implementing their ground systems, as well as significantly reducing a mission’s integration time and risk.

This work was done by John Kim, Sarma Velamuri, and Taylor Casey of Goddard Space Flight Center; and Travis Bemann of Honeywell. For further information, contact the Goddard Innovative Partnerships Office at (301) 286-5810. GSC-16041-1
