Scientists from the Saint Petersburg State University of Aerospace Instrumentation (SPbSUAI) have devised an algorithm capable of evaluating the time of information propagation and data transmission delay. According to them, this will enhance the reliability of modern aircraft. The corresponding research has been published in the scientific journal Sensors.
The authors of the study noted that the new algorithm synchronizes the “time” between system elements, thereby helping them function optimally.
Ensuring the smooth operation of aircraft and spacecraft requires error-free and timely data exchange between onboard devices. This goal can be achieved through a new data exchange technology developed by scientists from SPbSUAI.
The aircraft’s onboard network employs a so-called “time master” that broadcasts current time data across all broadcast channels, ensuring timely transmission of time information to each device onboard.
Saint Petersburg scientists have devised a method to assess potential network failures when broadcasting data to an excessive number of devices. This will improve the performance of onboard devices and reduce errors.
Researchers focused on the impact of network structure with multiple devices on data propagation time. As a result, their method will enhance the reliability of aircraft and spacecraft.
The new technology is named SpaceFibre. Currently, scientists are working on refining this standard.
