The current geopolitical landscape is making the topic of timing in aerospace and defense of particular interest within the WSTS community, especially as related to the increasing need for robustness and resiliency in the timing in navigation and guidance systems. Some of the solutions and challenges addressed by the telecom industry, have often been applied to other industries. While solutions applied to the Aerospace and Defense sector are typically developed in isolation from other industries, some of the solutions developed to support the telecom industry can be valuable in also in the Aerospace and Defense context. In particular, being telecom one of the key critical infrastructures, similar challenges related to the needs for an increased resiliency and robustness in timing must be addressed. Starting from inputs from partners that active within the Aerospace and Defense sector, this talk will provide an analyse on how telecom’ solutions and standards related to resiliency and robustness in timing, could be applied to a context as the Aerospace and Defense.
