Aircraft Position Transponder, 1924-1929
01
Artifact Overview
A transponder uses radio signals to identify the position, call sign, and altitude of aircraft. When the pilot pressed a button on this unit, it sent a radio signal called a "squawk code" down to ground controllers. This early transponder was used for a commercial route--its buttons are marked with several Indiana cities and signals for bad weather.

During his polar expeditions, Richard E. Byrd relied on navigational instruments not much changed in 200 years. Byrd's sextant measured the angle between an astronomical object -- the Sun or a star -- and the horizon. Based on the time of day it was measured, this angle was used to determine Byrd's position on a navigational chart.
