For crash prevention the outputs of MEMS sensors need to be foolproof, since only milliseconds can make the difference between life and death during a major accident. ADI's quad-differential gyros use redundancy and differential noise cancellation to nix any sensor mistakes before they happen.
This is marvelous technology. Caltech and UC Irvine have been developing it for years. Not degenerate, though, so higher performance not possible.
A new generation of symmetrical devices are coming out soon with drift rates as low as 0.02 deg/hr and ARW of 0.003 deg/ rt hr and thermally compensated by a firm in California.
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
