Commercial, Industrial, Standard Military and Space: What These Component Labels Mean, and Where CAST and SAST Parts Lists Fit In
A supplier describes a chip as “space grade.” A procurement specialist wants to know whether it appears on an approved-parts list. At a program review, an engineer asks a different question: Can the device meet mission requirements in this particular circuit position? These questions may sound repetitive, but they are not asking the same thing.…

Who Is Powering China’s GW Constellation? A Look at the Five Leading Satellite Institutes and Companies Behind It
Advances in phased-array radar and synthetic aperture radar (SAR) technologies are not only enhancing Earth observation capabilities but are also becoming a cornerstone of low-Earth-orbit (LEO) broadband communications satellites. A satellite’s phased-array antenna is essentially a phased-array radar operating in communication frequencies. Key radar technologies such as rapid beam steering, parallel subarray operation, and grating…
