they use light-years to determine the space between objects in space
You can use Radioactive Tracers to locate leaks in a faulty pipe system, to determine the amount of fertilizer absorption in plants, or to diagnose diseases.
If you are inside the train then you can use a device called an accelerometer. If you are outside the train then you can time how long it takes the train to travel two successive distances, and use the SUVAT equations to determine it speed over each of the distances.

No, they are not objects at all. They are abstract concepts we use in reference to objects. We cannot perceive them with our senses. They are nonphysical. They are just measurements we use to quantify physical objects that we can perceive.

an instrument that use echolocation to locate objects
SONAR
sonar
Sonar uses echoes to locate objects by bouncing sound waves off them and detecting the echoes.
Sonar
Something called echo-location
it seems humans use echolocation to find certain specific things they really need or objects and mainly sound
Well they can see. They also use echo location of sorts aswell though.
The main technique that bats use to find their way around their environments is echolocation. This is when the bat makes a squeak and uses the echo from that squeak to determine what is around it. Bats use echolocation to avoid objects such as buildings and trees and to locate prey, such as insects.
They use ultrasonic. The sound they use to locate objects that may be invisible.
Bats - and dolphins. They both use sound waves to find food.
