Aircraft collision prevention/poor conditions boat navigation having elements transmitting/receiving alternatively with transmission step less than reception step and reception step randomly duration varying/processing alert generation.

摘要

The communications system between elements transmits and receives alternatively for each element on the same frequency. The transmission duration step is less than the reception duration step. The reception time varies randomly. Each element can process digital words received, switching an alert or generating an action when a set proximity between elements is detected. The communications system between elements transmits and receives the same frequency alternatively. The length of the reception time is varied randomly, and when a set power level is exceeded an alert or an action is generated.
