Research on Key Technologies of Marine Maritime Positioning Equipment Based on Beidou RDSS
Aiming at the positioning problem of ships at sea,using the position reporting function of Beidou short message de-vice,through the key technology research and experiment of positioning and communication modules,a complete set of Beidou re-al-time positioning and communication system is designed,which realizes the monitoring of the position of fishing vessels and the command of rescue of fishing vessels in distress.Beidou short message equipment uses the Beidou-2 satellite system to realize navi-gation and positioning,two-way short message transmission and receiving,timing and other functions.It solves the practical prob-lem of high communication distance and high communication cost.It has the characteristics of strong real-time performance,high communication frequency,high positioning accuracy,strong applicability and large transmission power.
