MOIMS-SC-Archives -- MOIMS-Spacecraft Monitoring & Control
About MOIMS-SC-Archives	English (USA)
There is a general trend toward increasing mission complexity at the same time as increasing pressure to reduce the cost of mission operations, both in terms of initial deployment and recurrent expenditure. Current closed, or monolithic�, mission operations system architectures do not allow the re-distribution of functionality between space and ground, or between nodes of the ground system. The SM&C WG is defining a service oriented architecture consisting of set of standard services, which constitutes a framework that enables many similar systems to be assembled from compliant plug-in� components. These components may be located anywhere, provided they are connected via a common infrastructure. This allows components to be re-used in different mission-specific deployments: between agencies, between missions, and between systems. By layering the services themselves, the service specifications can be made independent of the underlying technology and the application coding language. Specific technology adapters enable the deployment of the service framework over a given technology. This in turn makes it possible to replace the infrastructure implementation as well as component implementations. It is also possible to transparently bridge between different infrastructure implementations, where these are appropriate to different communications environments (e.g., space or ground) or simply reflect different agencies deployment choices.
