Polish Armed Forces for many years have bet on innovative technological solutions in order to address the requirements of a changing world. The challenge set before Transition Technologies PSC was to propose and provide the means to create a digital feedback loop and a digital equivalent of a product (Digital Twin) inside the design office. Retrofitting of a combat vehicle included creation of a prototype for remote diagnostics… of a land vehicle for exploitation and operational performance data aggregation, analysis and archiving, as well as monitoring the usage of the vehicle. TTPSC has delivered a design of a physical layer of the solution,covering a military-grade central processing unit, wiring and sensors. Software, communication and data exchange layers have been implemented on top of that. As a result the design office received large amounts of data thanks to combat vehicle sensor implementation, such as monitoring of equipment operational effectiveness in real usage.
