I believe the GPS runs in two modes. One is continuous and can be used by applications and that can be turned off. However, there is a part of it - a locate on demand - that cannot be turned off (at least in this country). This is not battery draining because as soon as the location is gathered, the GPS sub-system is powered down again.
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.
