Measurement method of star sensor in marine remote sensing surveying and mapping

The traditional measurement methods of marine remote sensing surveying and mapping will be affected by external factors and can not accurately measure the surveying and mapping data. To solve this problem, a measurement method of marine remote sensing surveying and mapping based on star sensor is proposed. The satellite sensor is used to extract the data of remote sensing surveying and mapping at sea, and then the maximum likelihood method is used to process the data of remote sensing surveying and mapping at sea. On this basis, the precise measurement and mapping data are obtained by applying the measurement model of remote sensing surveying and mapping at sea. Considering the problem ofgravity acceleration, the velocity sensor should be introduced to compensate the velocity. Thus, the design of measurement method for remote sensing surveying and mapping at sea based on star sensor is completed. Finally, through simulation experiments, the accuracy of the two methods is compared. The experimental results show that the accuracy of the method is higher than that of the traditional marine remote sensing surveying and mapping measurement method.

The article analyzes the problems existing in traditional maritime remote sensing surveying and mapping measurement methods, and proposes a maritime remote sensing surveying and mapping measurement method based on star sensors to solve errors caused by external interference factors. Finally, the feasibility of this method was verified through simulation experiments. However, it was found in the experiment that there is a direct relationship between the magnitude of gravity and the results of the error. In subsequent research, emphasis should be placed on addressing the impact of gravity on measurement errors. I hope that the sea remote sensing measurement method based on star sensors designed in this article can provide reference value for future research.
