Definition of RBI
RBI or Relative Bearing Indicator is a navigation instrument that indicates the bearing of a target relative to the current position of the observer. It typically consists of a circular dial marked with degrees that correspond to the direction of the target, and a center pointer that represents the observer’s position.
The RBI can be used on ships, aircraft, and other vehicles to aid in navigation and target tracking. When used in conjunction with other instruments, such as radar or GPS, it can provide accurate information about the position and movement of nearby targets.
Overall, the RBI is a valuable tool for ensuring safe and efficient navigation in a wide range of environments, from open waters to congested airspaces. Its intuitive design and ease of use make it an essential component of any modern navigation system.
