I was confused about this too, I'm not quite sure but I think they measure the movement with GPS, they move about a centimeter per year. But the some people say that the motion is different and that you use a Seismometer, the same thing used to measure earthquakes.
Any ruler that has a division in centimeters. For somewhat longer distances you measure in meters. To know how long that is, take a piece of rope between your fingertips and measure the distance from the tip of those fingers to the outside edge of your other shoulder. If you're about 12 years or older, that distance is a meter.
The science of navigating ships from one location to another is known as navigation. It involves determining a vessel's position using various techniques such as celestial navigation, satellite-based GPS, and dead reckoning. Navigators calculate the course and distance to be traveled by considering factors like wind, currents, and weather conditions, ensuring safe and efficient passage. This discipline combines elements of geometry, physics, and geography to guide vessels accurately across water.
Different robots have different modes of motion and methods of control.Another PerspectiveAs the above answer suggests, there are multiple ways of guiding a robotic device along a fixed path, among those methods are: Embedded wire. Using this method, engineers place a wire in the flooring and inject a signal into the wire that a robotic device can detect. Antennae are then placed on the robot that can detect the relative wire location and the robot will know to correct guidance, either slightly right or slightly left.Inertial guidance. The robotic device can be given intermediate points to detect and given steering direction and distance traveled, the robotic device can calculate it's relative position and what actions must be taken to reach the goal. Multiple intermediate goals can be placed along the path and the robotic device can "sense" intermediate points with RF antennae, magnet sensors (meaning that magnets must be installed in the floor), video sensors (meaning that guidance images such as bar codes or other identifying markers must be on the floor or walls)GPS guidance, if the robotic device can calculate a current position and direction, it should be able to calculate what is necessary to get to the goal destination.This names just a few. Robotic guidance systems are limited only by the creative ability of the engineers.
To find your way to your destination.
You could use satellites with GPS to identify the location of the points that are furthest East and West. The GPS system may give you the distance between the points. Otherwise, you need to measure this along the Great Circle.You could use satellites with GPS to identify the location of the points that are furthest East and West.

Cities have GPS coordinates for their geographic centers. Distances are usually measured betweem them.
To calculate distance across waterways, you can use nautical charts or GPS technology. Nautical charts provide scale and coordinates, allowing you to measure distance using tools like calipers or by calculating the difference in latitude and longitude. Alternatively, GPS devices can give precise distance measurements based on the coordinates of the start and end points. For longer distances, the great-circle distance formula can be applied to account for the curvature of the Earth.
The distance between a boat and a diver can vary significantly depending on their respective locations. It can be measured using GPS coordinates or by using visual markers. If the diver is stationary, the distance is simply the straight line between the two points. If the diver is moving, the distance may change continuously.
To find the distance in kilometers between two locations, you can use online mapping tools like Google Maps or GPS devices. Simply input the addresses or coordinates of the two locations, and the tool will calculate the distance for you.
The main reason golfers use GPS is that it gives them a more accurate reading of the distance between two points. This allows them to adjust their stroke as needed so they do not undershoot or overshoot their target.
Nautical Miles. The easiest way nowadays, though, is to use a GPS
The distance of a lake can be measured by using GPS devices, surveying tools, or mapping software. Alternatively, you could calculate the distance manually by using triangulation methods or by walking the perimeter of the lake and recording the distance covered.
Distance can be measured using physical methods, such as a measuring tape or ruler, which provide direct, linear measurements between two points. Alternatively, distance can be measured using technology, such as GPS or laser rangefinders, which utilize satellite signals or laser beams to calculate distances accurately over longer spans. Both methods are valuable depending on the context and precision required.
A gps golf range finder is used by golfers to see the distance to the hole, and also the distance between the golfer and the various hazards of the course.
The Garmin Approach GPS will help you in being able to tell the distance between you and another object by an alert that sounds when you are too close.
To measure the slope of a stream, you can use the formula: slope = (change in elevation) / (horizontal distance). First, determine the elevation difference between two points along the stream using a level or GPS. Then, measure the horizontal distance between those points on a map or with a measuring tool. The resulting slope will provide a ratio that indicates the steepness of the stream's gradient.
