Other procedures might be utilised, together with gyroscopes, magnetometers, and GPS receivers.
The navy forces of a few nations, notably the United States Military, continue to challenge discipline compasses with magnetized compass dials or cards in place of needles. A magnetic card compass is normally equipped by having an optical, lensatic, or prismatic sight, which enables the person to go through the bearing or azimuth off the compass card when simultaneously aligning the compass with the target (see Picture).
