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.
