In order to improve using accuracy of agricultural GPS, by analyzing the error of point, polyline, polygon, several methods are produced such as arithmetic average value, least squares, adding control points, etc. Their principles, features and limitations are also analyzed and discussed.
为了进一步提高农用GPS的使用精度,研究了提高精度的方法,通过对点、线、面等误差的分析,提出了应用算术平均值法、最小二乘法、加入控制点法等多种提高精度的方法,分析和讨论了它们的原理、特点与应用局限性,并建立了加入控制点法中的误差平差法的数学模型。
