Gyro Repeater - is a navigational compass (under the control of a gyroscope) which indicates true north. A gyrocompass is an imperative instrument in all marine ships or naval vessels. This can detect the direction of true north and not the magnetic north.
Azimuth Circle - consists of 360 degrees. Ninety degrees corresponds to east, 180 degrees is south, 270 degrees is west, and 360 degrees and 0 degrees mark north. The word "bearing" is sometimes used interchangeably with azimuth to mean the direction (the degree reading) from one object to another.
