Transmission Block

We have found a deep base in the market place amongst the airfield block system manufacturers located in India. We ply a wide spectrum of aircraft block system and automatic aircraft block system available in diverse models. Blocks in the AircraftWhat are the Functions of These Blocks? The different blocks of the system are as explained below: 1) Weather Parameters : The different weather parameters to be broadcast using ATIS are monitored here. The monitoring is done on a continuous uninterrupted basis. The signals available from the sensors are properly conditioned and then sent to the ATC. 2) ATC & Computer : Here the weather parameters obtained from different sensors are checked for correctness on a computer terminal. It is this place where the data available is converted into a proper format and then using proper software is converted into voice message. The output voice message is also checked for correctness. The output is then sent to the transmitter where the data and voice are transmitted in proper format. Transmitter Circuit :3) Modulation Circuit : In this block the voice data available from the PC is modulated using FM modulation. The main consideration for the FM modulation is that the reception of the voice data must be fully error free and free from noise. The aviation band wireless set is used for transmission. Receiver Circuit :4) Aviation Wireless Set : This block is available in the aircraft that is going to land or take off. In this block the information broadcasted by the ATC is received and then demodulated. The demodulated data is the voice. 5) Microphone : The voice data available after demodulation of the received data is given to the microphone and this is available to the pilot as a listening aid for the ATIS information.
