ABSTRACT: The article deals with problems of information flow drop-outs at Critical Geographic Information Systems (CGIS). CGIS has high demand on availability of input and output data and must provide data analysis in very short time. Online CGIS has all input data available in real time or very close to real time. If there is a data flow drop-out the Online CGIS goes to offline mode. Offline CGIS must use different approaches to overcome the shortage of current data. The experiment depicted in the article use constructive simulation connected with the Czech military CGIS to prove the idea of using simulation method to predict unit position in the real situation. Experiment results reveal the maximum time interval in which the predicted unit movement calculated by simulator is still suitable for operational use in military CGIS.
