Instrument for far-field control FFM 734

Is used for position control of course centerline and output characteristics of course radio beacon in far-field zone (on the opposite end of the lineup))

Key peculiarities:

  • conformity with FAR and ICAO requirements
  • small amount of devices
  • reduced power consumption of prime equipment
  • forms part of «Complex 734» with single unified system of control and management
  • unification with «Complex734» products

General characteristics:

  • measurement of parameters: sum of depth modulations, difference of depth modulations, power level of signal
  • possibility to set and change parameters from remote control and monitoring system (RCMS 734)
  • distance monitoring and control
  • the beacon maintenance mode is uninterrupted, 24-hour, does not require constant staff assistance
