摘要GPS定位技术在各项工程中愈发广泛，良好的GPS导线网的设计也会有利于城市规划尤其是在地形测绘和各种测量工作中，加之随着国民经济的发展，徐州市作为一座历史悠久的古城，也更需要合理的规划。考虑到GPS具有精度高、速度快、费用省等特点，所以决定采用GPS定位技术来全面布设徐州市二三等成市控制网。76483

该网点采取边点混合连接的方式，规划了涵盖徐州云龙，泉山，铜山，鼓楼四大区域，因为徐州老城区坐落于这个范围内，而我们为了更好地使徐州建设更加快速而精确，该GPS导线网共设置了二等点6个，三等点24个，利用六台接收机在五个工作日内完成。本文还介绍了GPS观测时所需要注意的问题并以此来减少误差，还有对GPS接收机的操作及对数据的处理。

Abstract  GPS positioning technology in the engineering is becoming increasingly widespread and good GPS traverse network design will also conducive to urban planning, especially in topographic mapping and measurement work, coupled with with the development of the national economy, Xuzhou City as a city with a long history, also needs to be reasonable planning。 Taking into account the GPS with high precision, high speed, cost and other characteristics, so the decision to use GPS positioning technology to fully set the city of Xuzhou, city, the two or three control network。 The network take the side of mixed connection, planning covering Xuzhou Yunlong, Quanshan, Tongshan, Gulou four regions, because of the old city of Xuzhou is located in this range, and we in order to better enable the construction of Xuzhou more quickly and accurately, the GPS wire were set up the second point 9, three points 24 using six receivers within five working days to complete。 This paper also introduces the problems that need to be paid attention to during the GPS observation and to reduce the error, as well as the operation of the GPS receiver and the data processing。 

Key words：GPS traverse network  the side of mixed connection the problems that need to be paid attention to  the data processing。

1。1  地理位置

  徐州的战略位置自古以来占据着相当重要的位置，地处江苏、山东、河南、安徽四省交界，号称五省通衢，是我国各种交通的枢纽。其中徐州还有两大铁路干线，分别为京沪，陇海，两大铁路干线相交于徐州，同时，还有诸多的国家高速公路主干线也汇集于徐州，诸如连霍、京福、京沪等，由此可见，徐州的地理位置在我国所占据的重要性。
