Non–Directional Beacon Receiver
Non-directional beacon monitor/arlarm receiver is used to receive signal of NDB transmitter located at NDB Landing station or NDB Enroute station. Purpose to serve the air traffic controller or relevant people in monitoring continuously the operation of the stations in the civil flight operations. The receiver manufactured by Air Traffic Technical Company Limited, is a kind of dedicated radio receiver, working at long wave (wavelength m) with the high sensitivity and selectivity, easy operation. The receiver operates stably in different environmental conditions.
TECHNICAL PARAMETER:
- Input power 220VAC or 12VDC
- Input sensitivity ≥ 3µV
- Output speaker: 1W
- Operation in the frequency range 190kHz - 650kHz
- Putting on the table or in rack 19-inch
- Operation in one of five frequency band as following:
o 190-245kHz
o 245-315kHz
o 315-415kHz
o 415-535kHz
o 535-650kHz
The receiver tests and warns of the following cases of the transmitter:
o Power of the Transmitter decreases by 50% as the nominal
o Modulation depth decreases by 50-60% as the nominal
o NDB transmitter generates tone continuously
o Frequency of NDB transmitter deviates ± 2kHz
o Alarm by 25kHz tone or LED
o Represents the frequency of the transmitter
Antenna of the receiver is a loop antenna suitable for deployment.
Characteristic
