GPS receivers using two or even more antennae mounted separately and Mixing the data using an inertial motion unit (IMU) can now achieve 0.02° in heading accuracy and also have startup situations in seconds as an alternative to several hours for gyrocompass techniques. The devices correctly ascertain the positions (latitudes, longitudes and altitude) with the antennae about the Earth, from which the cardinal directions might be calculated. Manufactured principally for maritime and aviation applications, they may also detect pitch and roll of ships.
Ultimately, Earth's magnetic subject is not really uniform all all over the world. Improvements in altitude and geographic landforms in specific localities might cause disturbances that have an effect on the accuracy of a compass.
This magnetised rod (or magnetic needle) is then put on a very low-friction area to permit it to freely pivot to align alone Together with the magnetic industry. It really is then labeled Hence the person can distinguish the north-pointing within the south-pointing end; in contemporary Conference the north stop is usually marked in a way.

This kind of devices were universally applied as compasses until finally the creation in the box-like compass with a "dry" pivoting needle, someday close to 1300.
