ifferences. The measured amount of time—in millionths

measurements of relative times of arrival are used to
determine position, according to the Loran-C system.
tide
The vertical rise and fall of water caused by the gravitational
pull of the moon and sun.
track
A sequence of position measurements, or a desired line of

receives ultrasonic beams that determine seabed conditions
