👉 The Gradiometer is a device used to measure the angle of elevation of an object from a given point on the ground, usually at a fixed distance above the surface of the ground. It is commonly used in navigation and construction engineering. The Gradiometer works by measuring the vertical distance between the observer and the object being measured, as well as the horizontal distance from the observer to the object's position. This information can be then used to determine the angle of elevation, which is the angle at
