= Tellurometer
{wiki=Tellurometer}
The Tellurometer is a precision distance measuring instrument that uses microwave technology to measure distances by calculating the time it takes for a microwave signal to travel between two points. Developed in the 1950s and 1960s, the Tellurometer was one of the first devices to use this technology for surveying and geodesy. The instrument works by sending a microwave pulse from a transmitter located at one point to a receiver at another point.
