Abstract

AbstractResearchers and manufacturers use the Precise Point Positioning (PPP) technique. After the phase biases of the satellites are resolved from GNSS networks, they are broadcast to users as Fractional Cycle Bias (FCB). In this study, FCB products provided by WUHAN, CODE, CNES and JAXA services were downloaded and PPP Ambiguity Resolution solutions were realised by Net_Diff software. For ten days in 2022, 24-hour observations were collected from 40 International GNSS Service stations. As a result, it has been observed that WUHAN and CODE services provided the ±1 cm or ±5 cm accuracy level by converging in short-term observations.Keywords: PPP-ARConvergence timeFractional cycle biasGNSSInteger ambiguity AcknowledgementsWe would like to thank the International GNSS Service (IGS) for data and reference product support, and Wuhan University for Net-Diff software. Fig. 1 was plotted by using Generic Mapping Tools (Wessel and Smith Citation1998).Disclosure statementNo potential conflict of interest was reported by the author(s).

PPP-AR技术在不同FCB产品服务下的性能研究

研究人员和制造商使用精确点定位(PPP)技术。从GNSS网络中解决卫星相位偏差后，将其作为分数周期偏差(FCB)广播给用户。本研究下载了武汉市、CODE、CNES和JAXA服务提供的FCB产品，利用Net_Diff软件实现了PPP歧义解决方案。在2022年的10天里，从40个国际GNSS服务站收集了24小时的观测数据。结果表明，武汉服务和CODE服务在短期观测中通过收敛提供±1 cm或±5 cm的精度水平。关键字:PPP-ARConvergence时间分数周期偏差gnss整数模糊度感谢国际GNSS服务(IGS)提供的数据和参考产品支持，以及武汉大学提供的Net-Diff软件。图1是用通用制图工具绘制的(Wessel和Smith Citation1998)。披露声明作者未报告潜在的利益冲突。

期刊介绍： Survey Review is an international journal that has been published since 1931, until recently under the auspices of the Commonwealth Association of Surveying and Land Economy (CASLE). The journal is now published for Survey Review Ltd and brings together research, theory and practice of positioning and measurement, engineering surveying, cadastre and land management, and spatial information management. All papers are peer reviewed and are drawn from an international community, including government, private industry and academia. Survey Review is invaluable to practitioners, academics, researchers and students who are anxious to maintain their currency of knowledge in a rapidly developing field.
