SYSTEM FOR GLOBAL AUTOMATIC CONTROL OF TRANSPORTATION MEANS DURING NORMAL AND EXTREME SITUATIONS

摘要

The invention relates to control systems and is directed at defining the state of transportation means (TM) in normal and extreme conditions. Each TM is fitted with a power-on radio-beacon station (RB) whose signals are retransmitted by means of geostationary Artificial Earth Satellites (AES) of the integrated variety to mated ground stations for reception of information. In extreme situations of TM, the transmission of information from RB is carried out continuously by signal sets with a gap of up to 1 within the narrow band in a wave-range of 400 MHz which is provided for transmitting emergency signals with the aid of AES. In the normal conditions, signal transmission is carried out in a narrow adjacent band with intervals between sets of greater than 10 sec. An 20-30-fold increase of a transfer bandwidth of the system is ensured by means of a synchronous transmission of the information sets from RB one after another with small time gaps. Synchronism is obtained by means of accurate time marks emitted by RB receivers from navigation systems of the earth satellites of GPS and /or GLONASS.
