Jul 9, 2017 · Wadley built a device to probe the ionosphere that surrounds the earth. But his first exciting invention was the Tellurometer in 1959. This surveying instrument uses radio waves to measure distances. It’s accurate to the millimetre over 80 kilometres, and is …

Trevor Lloyd Wadley, the inventor of the Tellurometer, was born in 1920 in Durban, lived all his life in South Africa, but travelled overseas both during World War 2 and later in relation to his inventions.

It was invented by Trevor Wadley of the Telecommunications Research Laboratory of the South African Council for Scientific and Industrial Research (CSIR). He was also responsible for the Wadley Loop receiver, which allowed precision tuning over wide bands, a task that had previously required switching out multiple crystal oscillators .

Jan 28, 2018 · The invention that made Trevor Wadley most famous was the Tellurometer (literally “earth measurer”), an accurate distance-measuring tool that used radio waves.
