摘要:
通过在震源船上部署3套GPS接收机,并对3个点的位置信息进行汇总和压缩,利用北斗短报文将压缩后的位置信息推送到陆海联测指挥部,实现对震源船航速、航向的实时监控.根据3个点位信息计算的实时震源船航向,有助于准确把握震源船在进行固定点悬停激发时的航向,克服了以往使用前后两个时刻推算的平均航向代替实时航向等问题.使用我国自主知识产权的北斗短报文进行通讯,大大提高了系统的安全性、可靠性和稳定性;同时陆海联测指挥部可以实时查看震源船是否按事先设定的测线、事先设定的速度和航向进行作业,有效保障了监控平台对震源船的监控,进一步提升安全生产的风险控制能力.

Abstract:
In this paper, with collected and compressed the position information of the three GPS receivers installed on the source ship, the compressed information is pushed to the land and sea joint detection command center used the Beidou short message to realize the real-time monitoring of the speed and heading of the ship. The real-time heading of the ship calculated based on the three GPS receiver information helps to grasp the heading of the ship in the fixed point operation accurately for the problems of the average heading calculated in the past two times before and after the use of the real-time heading. The use of Beidou short message with China’s independent intellectual property rights, the safety, reliability and stability of the system are greatly improved. In addition, the command center can check in real time whether the ship is operating according to the preset survey line, the preset speed and heading, which effectively ensures the ship under the command center monitors and improves the risk control capability and safe production.
Key words:  marine remote  Beidou short message  land and sea joint detection  position tracking  multi-point tracking
