Special Features:

Ninth plus blink modified

Properties:

A receiver for signals from an electronic system of hyperbolic navigation utilizing a minimum of three shore-based transmitters. The "master" station transmits a pulse, which is radiated into space, and also triggers through precise time delay circuits the "slave" stations, so as to produce electromagnetic "fixes" for navagational use of surface vessels and aircraft. Transmitters are self-triggered, navagation charts are required, and usable data is developed by interpolation between display data and associated charts.
