摘要
针对水下目标的定位需求,在探讨GPS定位原理和水下超声定位原理基础上,提出了一种基于GPS实现水下定位的实现方法。给出了该方法的工作原理和具体工作过程。通过分析和计算GPS定位误差、水下定位误差,得到了这种定位方法的总体误差。分析和计算结果表明基于GPS实现水下定位的设想可能具有一定的实用价值。
In order to position underwater object, a method for underwater positioning on GPS is presented, based on GPS and ultrasonic position. The principle and process of the method is explained. The total error is obtained by analyzing and calculating spacial and underwater positioning error. The result shows that Method of underwater positioning on GPS is maybe possibly practical.
