Radio Remote Control System for Airport Visual Navigational Aids.

摘要

This is an evaluation unit to prove the feasibility and reliability of radio remote control for airport visual NAVAIDS. Reliability includes radio link dependability, equipment dependability, and message security. The radio link is assured by directional antennas and large power margin; the equipment is designed to MIL Standards, and the message is triple encoded. The half duplex system is so formatted that only one station can transmit or receive at any one time. This combination insures that the messages will be successfully communicated without inter-station interference, in the noisy EMI environment of the airport, and through unfavorable conditions of terrain and weather. Modular construction permits growth to 10 remote stations with 12 discrete functions per station. (Author)
