The Update IV Testbed uses scenario files to control the execution of a test. The scenario file contains Ada code to update the operational database with position and sensor contact data for targets. The testbed executes these calls sequentially as directed causing the appropriate position and contact updates. Normally, the scenario files have to be built manually by placing the correct Ada calls in the file with the data to cause a target position to change, or cause a sensor to report a contact. To cause target movement, each new position must be calculated and entered into the scenario file. The ATSG automates the scenario file construction process. It will form the correct Ada calls for positioning and sensor contact from the user supplied input data. The input files for ATSG contain movement dynamics and contact information for each target. From this data the ATSG formats the correct Ada call, automatically calculating and updating position based on the movement model given in the input file. Sensor contacts are added as directed by the input file commands. The ATSG allows multiple scenario files to be generated quickly with little manual calculations. These files can then be used by the Update IV Testbed program which tests Correlation, Collocation, and other functions of the Update IV software.
