NuWaves has introduced the Vampire NW-1553-ML-VA01, a MIL-STD-1553 anomaly detection and data recording module. It is an ethernet data diode capable of bus monitoring and logging and records all the energy on the MIL-STD-1553 bus to an internal SD Card to allow for post flight and test analysis along with playback of the recorded MIL STD 1553 traffic (using AFRL’s Transfusion product).
MIL-STD-1553 is a military standard published by the United States Department of Defense that defines the mechanical, electrical, and functional characteristics of a serial data bus. It was originally designed as an avionic data bus for use with military avionics but has also become commonly used in spacecraft on-board data handling (OBDH) subsystems, both military and civil. It features multiple (commonly dual) redundant balanced line physical layers, a (differential) network interface, time division multiplexing, half-duplex command/response protocol, and can handle up to 30 Remote Terminals (devices).
One directional data flow offers safe and secure implementation into any MIL-STD-1553 data bus. Providing up to 10 hours of data recording, Vampire can be utilized for an array of bus monitoring activities including: predictive maintenance, reverse engineering, anomaly detection, and as a real-time secondary display. It can be used with commercial-off-the-shelf (COTS) Ethernet tools, bus maintenance monitors and alerts, anomaly detection of bus traffic, statistical analysis of bus health during flight, deep dive post forensics analysis of MIL-STD-1553 traffic (ICD verification, predictive maintenance, etc.)
The Vampire module can convert the MIL-STD-1553 bus traffic to Ethernet UDP packets. It allows for real-time anomaly detection and is an additional method of recording bus traffic (external laptop needed). The module comes in a compact package and consumes 400 mA of current at 28 VDC.
