For decades, measuring velocity has relied on external references like GPS or lasers. But what if we could ditch the external clutter and measure velocity directly through a platform’s internal forces? This is the ambitious goal of the Defense Advanced Research Projects Agency’s (DARPA) Veloci-RapTOR program. Velocity measurement is critically …

The Defense Advanced Research Projects Agency (DARPA) is renowned for its forward-thinking initiatives that drive technological innovation. One such initiative, the COmpact Front-end Filters at the ElEment-level (COFFEE) program, is a testament to DARPA’s commitment to advancing science and technology. This program seeks to revolutionize radio frequency (RF) filter technology, …
