摘要
导出了计算地形起伏引起的高程异常的实用公式，该公式特别适用于地形复杂地区，能避免中央区域的积分奇异。在此基础上建立了顾及地形影响的ＧＰＳ正常高求解的数学模型。文中讨论了两种ＧＰＳ正常高求解的方法，并通过实际工程算例验证了本文所述方法的实用性和有效性。
Practical formulas for height anomaly caused by the undulation of terrain are deduced.These formulas are especially suitable in rough mountain areas and can effectively avoid the abnormal integral in the central region.Based on these formulas,mathematical models are proposed for solving the normal height in GPS network concerning terrain undulation.Two algorithms for solving normal height in GPS network are discussed.A practical example shows that the proposed algorithms are practical and effective.
