| 摘 要： | 将GPS点大地高直接转换成正常高,越来越广泛地应用于建立高程控制网的实践中。而要保证GPS点高程精度的关键是高程异常拟合模型选择的合理性。文中介绍了在狭长带状区域下利用正交函数法拟合GPS点高程的数学模型。并利用试验数据进行比对分析。结果表明,文中提出的方法计算具有算法稳定,成果合理的特点。

| Abstract: | The transition of geoid elevation surveyed by GPS to normal height has been widely used in the practice of height control network surveying in municipal engineering construction.The key to guarateeing the transition precision of geoid elevation to normal height is how to choose the fitting model for elevation abnormal.It introduces a method based on orthogonal functions for elevation abnormal fitting used in linear area.The test data shows that the result is reasonable and characterized with stabilizition |
