Interface Electronics & HILS

Mission-specific interface electronics — MIL-STD-1760 store interface units, DC-DC / AC-DC power electronics, and real-time hardware-in-the-loop validation platforms with MATLAB® and LUSI integration.

Store Interface Unit

aSIU

The Store Interface Unit manages launchers and stores on the platform — transmitting fire control commands to munitions and relaying status back to the FCS, while performing safety-critical functions during firing.

MIL-STD-1760 compliance — electrical and logical interface
Manages up to 8 munitions simultaneously (1–8+ slot packaging)
Electrical power and discrete signal transmission per functional flow
Store ICD data communication — status, LAR, control/monitor
Post-fire control of network-enabled weapons via data link
Launcher control and monitoring
Receives platform navigation data for store transfer alignment (TxA)
Hard real-time OS with store management system software

Power Electronics

Power Conversion & Supply Design

Custom power electronics designed, built and qualified in-house for platform and munition systems — from board-level converters to complete power supply units.

DC-DC converter design — isolated and non-isolated topologies, board-level to brick-format
AC-DC power supplies — including 115 VAC 400 Hz platform power conversion
Power conditioning & distribution — protection, sequencing and monitoring circuits
EMI filtering — input filters and transient suppression for harsh platform environments

Hardware in the Loop

HILS-200

A high-performance, real-time testing and validation platform for embedded systems, control algorithms, and sensor/actuator interfaces — evaluating system behavior under realistic, repeatable, fully controlled conditions without the physical environment.

MATLAB® integration — run Simulink® models as real-time plant models, validate controllers in closed loop, log and post-process in MATLAB
LUSI integration — physics-based environment simulation as digital twin; sensor-level IMU, GNSS, radar, LiDAR and EO data exchange
Scenario-based testing with repeatable conditions and fault injection
Optically isolated I/O, multi-channel buses, deterministic execution
