Such models are now becoming available, but they are limited in spatial or ... , and no global, dynamic, trapped radiation belt model is forthcoming. It is therefore vital to co-ordinate future modelling efforts in order to develop new standard models. '''To BUY this paper click http ...

The system has been designed to provide an environment which can efficiently capture spacecraft ... procedures following fault detection and isolation. Users of INTELMOD require no formal programming experience, as models can be constructed with user-friendly editors that employ a "drag and drop" approach using ...
