AN/GSM-333 Support Equipment System Support Equipment Systems Division (SESD) GEC Avionics Ltd, Airport Works, Rochester, Kent, P.O. Box 81999, ME1 2XX, England Telephone: (634) 844400 Telex: 96333 Facsimile: (634) 816263 GEC Avionics Inc. 2975 Northwoods Parkway, Norcross, Atlanta, Georgia 30366, USA Telephone: (404) 488 1947 Telex: 708447 Facsimile: (404) 449 6128 Support Equipment Systems Division (SESD) The Support Equipment Systems Division (SESD), is an autonomous trading unit of GEC Avionics Ltd., engaged in the design, development, and production of support equipment systems and associated engineering activities. The division, location at Rochester, Kent, England, occupies 71,000 square feet and employs over 320 people, developing automatic test equipment (ATE) systems and test program sets (TPS). The division has been involved in a number of major support equipment programs during its 30-plus years in existence, including the design and development of the AN/GSM-333 USAF MATE standard D-level support equipment system associated with the Standard Central Air Data Computer (SCADC) Program. This MATE program, the only MATE program awarded to an offshore supplier, resulted in the development and delivery of the only fully MATE-qualified support equipment system in the U.S. Air Force (USAF) inventory. AN/GSM-333 Support Equipment System The AN/GSM-333 MATE Support Equipment System was developed in response to USAF and U.S. Navy (USN) requirements for a D-level support system for the SCADC program. This program provides a standard air data computer system for 26 different types of USAF and USN weapon systems. The system, ordered in June, 1987, was developed to fully comply with the requirements for USAF MATE standard equipment. The first test system was installed at an Air Force depot facility in December, 1990. Further systems are due for installation during the first half of 1991. USAF MATE Standard The USAF MATE standards define an acquisition process used by the Air Force to procure support equipment systems. These standards enable the Air Force to procure support equipment systems at optimum life cycle cost, and define various standards and capabilities that must be observed during the system design and development process. Test Station Software One of the major elements defined within the USAF MATE standards is the use of Air Force controlled support system software. This software, the MATE Command and Control Software System (MCSS), is strictly controlled by the Air Force and provides a common software core to be used throughout the Air Force system. The AN/GSM-333 system uses MCSS Version 5.02, the latest version of this Air Force provided software. Test Station Hardware The AN/GSM-333 system includes the following test instrumentation:- Digital Multimeter (DMM) Oscilloscope AC Power Supplies Function Generator Angle Position Indicator Frequency Time Interval Meter (FTIM) Pneumatic Test Facility DC Power Supplies Programmable Load Synchro Resolver (Two Off) VXI Instrument Rack (Containing):- MIL-STD-1553 Interface Programmable Resistance Stimulus Precision DC Sources (Eight Off) MATE Standard Interface Connection Assembly (ICA) Digital Word Generator (DWG) All of the instrumentation used within the AN/GSM-333 system has been tested and approved for use on USAF MATE programs, including the Pneumatic Test Facility, developed by GEC Avionics Ltd. to meet the highly-complex pneumatic testing requirements of the SCADC system. All elements of the test system were developed in accordance with MIL-STD-28800 as required by the USAF MATE standards. Test Station Maintenance The AN/GSM-333 system has been designed to allow the Air Force to be completely organic in its D-level testing requirements. The system comes complete with all necessary self test, alignment and calibration facilities to allow the user to maintain and calibrate the entire system. Full supporting data was delivered as part of the SCADC program. Calibration of the test system is conducted using the standard USAF PATE calibration package. Test Program Sets (TPS’s) Twenty-Seven USAF MATE standard test program sets (TPS’s) were developed to provide full LRU and SRU diagnostic testing for the SCADC system. These TPS’s were developed in accordance with the Air Force MATE guides and follow the TPS development requirements of MIL-STD-2077. The diagnostic capabilities of these TPS’s are:- 100% Fault Detection Capability 95% of faults diagnosed to one faulty component 97% of faults diagnosed to two components 99% of faults diagnosed to three components Program Quality Assurance GEC Avionics Ltd. is a qualified MIL-Q-9858A supplier to the U.S. Department of Defense.
