Bearing Rate

Bearing Rate is the measure of how quickly the compass bearing to an object changes over time. Generally, it is measured in degrees per minute.

Bearing rate is a useful metric in fire control because bearing rate and range can be related to gun deflection. In some fire control mechanisms (such as on some Dreyer Fire Control Tables, a bearing rate might be entered into a bearing clock to help maintain an approximate bearing setting on appliances that use this, such as a dumaresq's dial plate.
