Based on these formulas, mathematical models are proposed for solving the normal height in GPS network concerning terrain undulation.
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。
It is more difficult to confirm the transformation relationship between geodetic height and normal height. This is main reason of restricting application of GPS height into use.
指出GPS大地高与正常高之间的转换关系较难确定是限制GPS高程应用的主要原因。
Recently utilizing GPS/gravity to determine the normal height were adopted by some geodetics.
近年来人们往往利用GPS/重力来确定正常高。
