About this document
Electronic Distance Measurement Overview by Shaik Munna is a document available to read on EtoBox.
The document discusses electronic distance measurement (EDM) instruments. It describes how EDM instruments work by measuring the time it takes for electromagnetic waves to travel between two stations to calculate distance. There are two main methods - pulse techniques which measure time of flight, and phase difference techniques which measure the phase difference between emitted and received signals. Modern EDM instruments are highly accurate, with errors of only a few millimeters plus parts per million of
