MOIS Test Harness
The integrated man-machine interface provided by Validator enables validation results to be recorded at both the level of the procedure (including nested procedures) and of a particular step or statement. Validation information, including comments, can be entered on the display and submitted back to the procedure databases to keep a record of procedure execution during spacecraft validation tests and simulations. Additional functionality includes a stopwatch feature to time the execution of the procedure or particular step sequences.
Test Harness provides a source and sink for telemetry and telecommands, replacing the need to link to a control system and simulator for initial procedure validation.
Test Harness allows an engineer to test and validate functionally the logic and flow of procedures. It allows a level of procedure validation to be achieved prior to delivery of control systems and spacecraft simulators. As a consequence of using the MOIS Test Harness, simulator and control system resources can be optimised during the procedure validation process by allowing functional tests of procedures to be completed prior to the allocation of simulator and control system time.
