通过对导航坐标数据进行变换,可以实现Garmin导航仪在航空物探测量的导航应用。首先,对Garmin导航仪和航空物探设备导航系统的导航方式进行了分析,指出了造成误差的原因。然后,介绍了一种比较简便的解决误差的改进方案,使得误差控制在行业标准允许的范围内,并指出了在实际应用中可能存在的定位精度和输入航路点工作量大的问题,对这些问题的解决方法做了详细的说明。以实际工作为例,Garmin导航仪应用于航空物探的飞行的导航时,测线的飞行指标的合格率为100%。说明其应用有助于提高飞行质量和数据的可靠性,有很广泛的应用空间。
By transforming the navigation coordinate data, the navigation application of Garmin navigator in aero-geophysical survey can be realized. First of all, the navigation methods of Garmin navigator and aero-geophysical equipment navigation system are analyzed, and the reasons for the errors are pointed out. Then, an improved scheme to solve the error is introduced, which makes the error control within the allowable range of the industry standard, and points out the possible localization accuracy and the heavy workload of input waypoints in practical applications. The solution to the problem has been explained in detail. Take practical work as an example, when Garmin navigator is applied to navigation of aero-geophysical flight, the passing rate of the flight index of the survey line is 100%. Indicating that its application helps to improve the flight quality and data reliability, there is a wide range of applications.
