Geomagnetic velocimeter |
摘要 |
A velocity measuring system utilizes a pair of magnetic sensors each mounted in a displaced location with respect to the other on a vehicle whereby such sensors passing over the same stationary base location at different times provide geomagnetic field signals to a correlator circuit for producing a value for the ground speed of the vehicle.
