what3words, integrated into RapidSOS dispatch, provides users with a simple way to communicate precise locations. It has divided the world into a grid of 10 ft x 10 ft squares, and given each square a unique combination of three words: a what3words address.

For example, ///tools.melted.studs takes you to the exact entrance to Jedediah Smith Redwoods State Park’s campground.

They call it RapidSOS but my eyes always see it as RapidOS.
