Originally published by the US Department of Defense (DoD) in 1973, Military Standard 1553 is a standard defining the mechanical, electrical, and functional characteristics of a serial data bus. The purpose of the Mil. Std. 1553 bus is command and control of line replaceable units (LRUs) as well as sharing data on a common bus. Originally defined for military avionics, 1553 has become common in both military and civil sectors for ship, ground vehicles, air, and spacecraft data handling subsystems including flight data recorders. Existing flight data recorders allow for data analysis in the event of an incident and for routine operational systems analysis. The difference between the bus logger and the flight data recorders is the bus logger’s ability to log all energy on the bus. This enables post-processing analysis of anomalies, unintended collisions, and communication exceptions. Additionally, existing data recorders are limited in what they can capture due to storage capacity.
Air Force researchers have developed a combined hardware/software solution to address these issues with high sample rates and removable memory. The information in the data stream is not demodulated until it is downloaded and post-processed. This solution will be an ideal forensics tool for lab or flight tests with piloted aircraft, drones, and driver or autonomous ground vehicles.
