Application of digital twin in space engineering using augmented reality and internet of things technology

Digital twin (DT) is the latest technology, which helps in generation of exact digital replica of the physical system. In this work, an in-house DT of a thermo-vacuum chamber and payload is developed. This res­earch paper covers the development and implementation of an in-house cross-platform software application, a mobile AR app, and a Microsoft HoloLens 2 application, which provides real-time sensor data with voice control. The objective of this research is to study the potential of DT technology in real time monitoring of testing of payloads in thermovac system. Results demonstrate that the developed software applications provide a comprehensive 1 : 1 scale 3D visualization of the chamber along with essential sensor parameters for users to monitor the chamber and payload status, leading to a more effective decision making
