- 摘要:
- 在沿海航行中，为维护船舶航行期间的安全，航海者需要注意船舶的准确位置，而船载智能定位终端系统的不断改进，推动着船舶在既定航线上稳定航行，其中的全球卫星导航系统在导航定位、科研测绘、城市智能交通等多个领域均有广泛的应用。为深入探讨船载智能定位终端系统地标定位的准确性，本文选取多模卫星信号中的GPS系统和北斗系统，以最小二乘算法的定权策略对其展开探讨，在基于多模卫星信号提升船舶的导航定位技术，使其优势互补，共同提高定位精度，最大限度地减少定位误差，充分保障船舶安全航行。
In coastal navigation, in order to maintain the safety of the ship during navigation, navigators need to pay attention to the accurate position of the ship, and the continuous improvement of the shipborne intelligent positioning terminal system promotes the ship to sail steadily on the established route. The global navigation satellite system is widely used in many fields, such as navigation and positioning, scientific research and mapping, urban intelligent transportation, etc. Accordingly, in order to deeply explore the accuracy of landmark positioning of the shipborne intelligent positioning terminal system, this paper will select the GPS system and Beidou system from the multimode satellite signals, and discuss them with the weight determination strategy of the least squares algorithm, aiming at improving the navigation and positioning technology of ships based on the multimode satellite signals, making them complement each other, jointly improving the positioning accuracy, minimizing the positioning error, and fully ensuring the safe navigation of ships.
