GBU-X Platform Emulator System (GPES)

WINTEC is developing an GBU-X Platform Emulator System (GPES) to enable testing for developmental store carriage or launcher systems, and associated weapon stores in avionics Systems Integration Laboratories (SILs).

The emulator will support full-up MIL-STD-1760 physical, electrical, and logical interface requirements normally present at an aircraft store-station connector. All safety-enable power and safety-enable discrete are represented.

Additionally, the MIL-STD-1553 data bus [Mux A and Mux B] will generate logical messages IAW the Universal Armament Interface (UAI) standard [UAI-PSICD- R04] message superset.

Specific aircraft-store sequencing required by the unique weapon configuration class are selected from the superset by Configuration Data Set (CDS) files. Normal aircraft digital data sequencing may include asynchronous, synchronous, and repetitive ‘Receive’ and ‘Transit’ message traffic as per the aircraft OFP software and the store-unique requirements. This sequencing is controlled by appropriate scripting programs.

The platform emulator minimizes the complexity of aircraft systems integration by simulating the aircraft functions in the SILs. The GPES also supports Miniature-Munitions/Store Interface (MMSI) and MIL-STD-1553 EBR interfaces for smart carriage systems sub-net buses.

The GPES was developed under Air Force Research Laboratory SBIR Phase II contract. (Q4 2016) (GPES is an ITAR-restricted item.)
