Abstract:   I n view of the existence of the pain points of blind spots and expensive costs to marine vessels by traditional supervision means,by using positioning、velocity measuring、time granting and the unique twoway short message communication function of BeiDou satellite navigation system,designed a set of vessels' courses supervision platform system based on BDS,and made use of it in the supervision of vessels’ route in Wuhan Port and Shipping Authority. The results proved the system can achieve the function of realtime positioning、velocity measuring、precious time granting of the vessels,and the function of the twoway communication between vessels, with the vessels’ monitoring center and with mobile phones,under the premise that the system does not depend on other communication technology. In addition,the system has the function of Collision and deviation warning,and the advantages of allweather, no blind spots, low rates, high reliability,and has great practical value.
