摘要
概要地介绍了ＧＰＳ测量的技术性能和一般要求。对ＧＰＳ测量中的基准转换、高程测量中误差产生的原因及提高ＧＰＳ测量精度问题进行了分析。
The author introduces normal technical requirements of GPS measurement.Some points in the production and application of Global Position System are analyzed covering datum,WGS84 geodetic coordinate system,the conversions between parameter coordinate system and WGS84 coordinate system, elevation system as well as application of GPS in measurement. The multinomial is convergent one and multinomial parameter has apparent physical implication in the measurement. However,as an important factor in the technical application of GPS,anomaly coorection of elevation will be studied further.
