摘要

摘要在本研究中,使用低成本的内部开发接收器来测试定位质量。分析考虑了低成本设备在测量工作中的实际应用。在网络解决方案中,基于低成本接收器的全球导航卫星系统定位的准确性可以通过在24小时和10分钟的观测会话中分别为1毫米和6毫米的基线长度的可重复性来表征。4个全球导航卫星系统接收器和3个全球导航系统低成本接收器的实地实验使建立精确的大地测量控制网络成为可能。对于水平分量和高度分量,用低成本GNSS接收器确定的控制点坐标的精度分别等于最大值17和40mm。因此,低成本的全球导航卫星系统接收器可以提供几厘米级别的定位精度,并可以支持陆地测量和大地测量监测活动。

Positioning performance with dual-frequency low-cost GNSS receivers
Abstract In this study, positioning quality is tested with the use of low-cost in-house developed receivers. The analyzes consider the practical use of low-cost devices in surveying works. In the network solution, the accuracy of the GNSS positioning based on low-cost receivers can be characterized by the repeatability of the baseline length of 1 and 6 mm in 24 h and 10 min observation sessions, respectively. The field experiment of 4 GNSS receivers and 3 GNSS low-cost receivers allowed for establishing a precise geodetic control network. The accuracy of the control point coordinates determined with low-cost GNSS receivers equals a maximum of 17 and 40 mm for the horizontal and height components, respectively. Therefore, low-cost GNSS receivers can provide positioning accuracy at the some centimeter level and can support land surveying and geodetic monitoring activities.
