HF automated adaptive radio communications mobile center

Purpose of the equipment

Mobile radio communication center provides:

• full automation of radio communication establishing and maintaining;
multiparameter adaptation depending on propagation conditions and interference environment via a deliberate change of operating frequency, data transmission rate within the range of 300 9600 bit/s and code rate from 0,4 to 0,8;
• data transmission in real time at the rates 1200 and 2400 bit/sec. via interface S1-E;
• use of active route sounding to select optimal radio communication frequency;
• high reliability of data transmission (at most one distorted sign per billion transmitted signs) through the use of error –correcting codes and automatic repeat request of distorted information;
• operation in radial network in data transmitting mode;
• Automated remote control and transmitter and receiver function check performance;
• Advanced tools of information cryptographic protection in asynchronous mode during data transmission;
• Radio communication both at parking places (at halt) and on the move;
• radio communication between the same type radio stations and old park radio stations as well;
• possibility to interface with local computer networks and automated control systems;
• automatic keeping of electronic hardware log;
• radio station synchronization through GPS and GLONASS satellite system by State Service of Time and Frequency standard time signals in HF stations’ network.
