Description
PURPOSE
BKSS Airborne communication system is designed for providing anti-jam open and secure radio telephone and telecode communication during the interaction with other aircrafts and ground control centers.
THE NUMBER OF RADIO COMMUNICATION CHANNELS
Three independent radio channels can be generated in the system by using simplex radio sets:
- two UHF-VHF radio sets, operated in the fixed frequencies mode (FRF mode) and in the antijam mode (ECCM mode);
- one HF radio set, operated in the FRF mode.
TELEPHONE RADIO COMMUNICATION
The system provides:
- two way simplex open telephone communication for the crew ( the commander and the second pilot) via two independent radio channels– in UHF-VHF and (or) HF range;
- two way simplex open telephone communication for the user(technician) in the cargo cabin via one radio channel –in UHF-VHF range (if it is not occupied);
- two way simplex secure telephone radio communication for one of the crew via one radio channel in UHF-VHF or HF range.
TELECODE RADIO COMMUNICATION (DATA EXCHANGE)
The system provides automatic secure data exchange by using anti-jam coding via one radio channel in VHF-UHF or HF range.
RELAYING
The system provides:
- automatic voice information relaying in the open operating mode by using two VHF-UHF radio sets in FRF and ECCM modes;
- automatic echo-relaying in the open operating mode by using one radio set in VHF-UHF range.
VOICE WARNING AND MESSAGES REPLAYING
The system provides:
- the helicopter crew (commander, the second pilot, and the user in the cargo cabin) voice warning about the onboard emergency situation (emergencies and dangerous flight modes) with automatic messages transmission to the ground control unit via selected telephone radio communication channel;
- standard formalized messages, received via telecode radio communication channel replaying.
INTERNAL TELEPHONE COMMUNICATION
The system provides two way internal telephone communication:
- between the helicopter crew men;
- between the helicopter crew men with the ground maintenance personnel (GMP), which used UNOP manpack items (up to three connection points) during the helicopter maintenance execution.
SIGNALS AND MESSAGES LISTENING
The system provides for the crew the listening to:
- radio navigation signals (NAV);
- automatic direction finder signals (ADF);
- any of two VHF-UHF radio sets guard receiver signals;
- special signal transducers signals (SST);
- one of the radio sets receiver signals (additional listening);
- emergency messages about onboard emergencies (repeated listening).
The system provides additional listening to one of the radio stations receiver.
CONVERSATIONS RECORDING
The system provides recording of the telephone conversations via internal and external radio communication between the crew and the user in the cargo cabin by the onboard tape recorder.
COMMUNICATION SCHEDULE
The system provides automatic communication schedule (preflight data) input from the external data carrier or via radio channel, as well as communication schedule input and correction during the flight.
THE RADIO SETS CONTROL
The system provides the radio sets control in the automatic mode according to the communication schedule and in the automatized mode from the control panels (B8-50 and B7-24 blocks).
THE SYSTEM VERSIONS
The system versions for installing at the different type of the aircrafts are created by changing its composition (its components (radio sets, control panels, etc. change for other standard ones), software correction in the MSPD unit and the standard testing execution.
