Navigational Beacons: AN/FRN-44 VOR

Designed in the 80's for service well into the 21st century, the Target Corporation AN/FRN-44 VOR is the perfect marriage of sophisticated navigational electronics and computer age data processing techniques. This latest generation of NAVAIDS gives the user troublefree, all channel, all solid state VOR system that can virtually troubleshoot itself. A standard display terminal provides both graphic and verbal indications and instructions to the operator allowing quick and easy troubleshooting and repair.

The Target Corporation solid state VOR navigational system is a rugged, highly reliable, modular, all solid state equipment which has been designed to meet the newest United States Air Force VOR requirements. The VOR has full remote maintenance monitor capability and features built-in fault isolation. The system is normally supplied with the Alford Loop Antenna Array. However, a slot antenna can be provided if desirable.
