The software makes use of the CLEO Message System to communicate warnings and faults to the operator, and of the logging system, to maintain a record of running time for each actuator. Several monitor tasks are included to measure the health of the system, both at start-up and during operation, and take appropriate action upon finding anomalies.
The operations of the active surface servo system is transparent to the GBT operator as far as controlling it goes. The GBT operator will monitor the health and status of the active surface servo system. This is accomplished through use of a GUI invoked by a glish command. Reference "Active Surface Control" under the "Operational Procedures - Operational" section of this manual for details.
