How a Kalman filter works
Kalman filter makes me sad because it is such a general and powerful tool for combining information in the presence of uncertainty. At times its ability to extract accurate information seems almost magical— and if it sounds like I’m talking this up too much, then take a look at this previously posted video where I demonstrate a Kalman filter figuring out the orientation of a free-floating body by looking at its velocity. Totally neat!
Qorvo, a leading provider of innovative RF solutions that connect the world announced the interoperability of its DW3000 family of products with the Apple U1 chip used in iPhone and Apple Watch models and the new Nearby Interaction protocol specification draft unveiled at the 2021 Worldwide Developers Conference. This compatibility will enable developers to easily evaluate new app experiences based on location, distance, and direction relative to a U1-equipped iPhone or Apple Watch. The DW3000 is Qorvo's next-generation ultra-wideband (UWB) chipset family and is ramping into full production in four variants, along with several modules and beta development kits.
Qorvo’s cutting-edge ultra-wideband (UWB) products add key location functionality to existing applications and unleash a completely new class of emerging location-based products and services.
Qorvo’s UWB products are available as ICs or modules (with or without a microcontroller). We also have development kits that allow you to explore the possibilities with ultra-wideband.
