GPS RTK在数字地形图测绘中的应用

摘要

The application of GPS RTK technology makes digitized mapping with high speed,high precision,less cost etc, and is approved by mapping industry. But the measurement precision of GPS RTK is also limited by satellite situation, weather change,high-level anormaly, stability etc. In the application of topographic mapping,the influential factors of GPS RTK accuracy are introduced, and the method to ensure the precision of GPS RTK is proposed.%GPS RTK技术的应用使得数字化测图具有速度快、精度高、费用省等特点,该技术得到测绘行业的认可.但是GPS RTK的测量精度也受卫星状况、天气变化、高层异常、稳定性等限制.该文介绍了在地形图测绘应用中,影响GPS RTK测量精度的因素,并提出了保障GPS RTK测量精度的方法.
