I think a yaw rate sensor is used in automobile stability and traction systems, but I'm no auto expert. -- Whpq 19:56, 16 August 2006 (UTC)Reply

Only two types of sensor?

Surely there are more? It is common on helicopters (and quite likely fixed wing aircraft, although I have no experience of them) to use an actual mechanical rate gyro, complete with little flywheel spinning at high speed, like any other type of mechanical gyro. The rate gyro is the simplest of the mechanical gyros, not having gymbals, just sensing the gyroscopic torque. The rate term was, when I was working in that field, used in the autostabiliser and autopilot systems of various types, digital in modern, and analogue on older aircraft.

It is probable that later aircraft use some kind of laser ring gyro or acoustic wave gyro to get not only rate but angle, as part of a more complex system, but I have no recent experience to back that up.

On a car you would use something cheap and long lasting but not necessarily particularly accurate. The mechanical rate gyro would probably cost upwards of £1000 nowadays and invariably have a limited life.

My point is that we should show that there are more than two types of gyro used, and perhaps someone with up to date information might care to elaborate? Tiger99 (talk) 13:16, 27 March 2019 (UTC).Reply
