目前我国正大力推进北斗卫星导航系统的建设,针对北斗卫星导航系统所具备的卫星定位导航功能与短报文通信功能,提出利用北斗卫星导航系统进行海上船舶应急救援及预警的设想,以提高海事部门在船舶处于危险情况下的应急救援能力,同时降低船舶发生事故的概率。主要阐述该系统的软硬件构成及系统的功能,重点介绍针对在海上移动网络信号较差的情况下使用北斗卫星导航系统的短报文通信功能进行应急救援与预警的方法。
At present, China is vigorously promoting the construction of the BeiDou satellite navigation system. In view of the satellite positioning and navigation functions and short message communication functions of the BeiDou satellite navigation system, this paper proposes the idea of utilizing the BeiDou satellite navigation system to carry out emergency rescue and early warning of the marine ships so as to enhance maritime affairs The emergency rescue capabilities of the department in the event of a ship being in danger and reducing the probability of an accident at the ship. Mainly elaborates the hardware and software of the system and the functions of the system, and focuses on the emergency rescue and early-warning method for the short message communication using BeiDou satellite navigation system under the condition of poor mobile network signal at sea.
