Ground to Space: Reviewing Aerospace Applications [From the Guest Editors’ Desk].

The aerospace sector has experienced major evolutions over recent years through structural changes, initiated a couple of decades ago, that led to the very dynamic field we witness today. This triggered the need for a dedicated IEEE Microwave Theory and Technology Society (MTT-S) Technical Committee (TC) addressing this broad topic. As a result, the TC-29 on Microwave Aerospace Systems was founded in 2020 and recently reported on its activities. It covers the wide range of aerospace applications, from the ground to the space segment and everything in between, including unmanned aerial vehicles (UAVs), high-altitude platforms, and more generally, atmospheric satellites. This focused issue is the first of two focused issues sponsored by TC-29, providing a good overview of key areas of development related to microwave systems for aerospace applications.
