The MSE evolved from prior efforts supporting integration and testing for JDAM on the MQ-9 Reaper UAV, as well as from SBIR-related research and development. For the Reaper-JDAM integration, a suite of modular components that include six Store/Rack Emulator Modules (SREMs) that simulate the real-time functionality of six JDAMS as reflected at the MIL-STD-1760 interfaces specified in relevant ICD revisions or UAI supplements.
Also included in this equipment suite is the Emulator Control Station (ECS) providing operator control and status monitoring of the active store simulations and bomb rack simulation embedded in each SREM. The ECS laptop PC communicates with each SREM via an Ethernet network. MSE configurations may range from a single ECS to SREM network to a single ECS to eight SREM network. SREMs may also be configured to operate as independent stand-alone units.
Each SREM is connected to the platform connector via a physical MIL-STD-1760 station umbilical cable designed to customer-required lengths. Through this interface each SREM monitors store/rack power (e.g., 115 VAC 400Hz, 28 VDC1), discretes (e.g., Address, 28 VDC DC2, Release Consent) and responds as a remote terminal (RT) to the MIL-STD-1553 Mux A and Mux B interfaces for digital data transfer.
The embedded models replicate the same interactive behavior as the selected Carriage or Mission Store. Examples of the store simulation functions include transfer alignment, Mass Data Transfer (MDT) of GPS ephemeris, almanac, and other file types, built-in-test (BIT), target transfer, and safety critical release sequencing.
MSE software is subdivided into a real-time embedded component hosted on the SREMs, and a non-real-time component hosted on the ECS. SREM simulation software executes using a real-time operating system (RTOS). The RTOS environment supports real-time simulation of platform-carriage-store functionality with deterministic performance and timing.
Enabled by its open system architecture, individual simulations representative of many Carriage and Mission stores may be selected for any platform or carriage station including mixed load- out configurations. Moreover, store simulations may be created or tailored to be compliant with Platform Annexes, Store Supplements, or legacy interfaces. Alternatives interfaces have supported customized solutions with RS-422 and Ethernet.
The ECS non-real-time software executes on a Windows operating system and supports operator interfaces (e.g., control, monitoring) via its Graphical User Interface (GUI). Together these components form a scalable architecture that provides emulation of various Carriage and Mission stores.
