Abstract

PPP-RTK (Precise Point Positioning – Real Time Kinematic) is a positioning method by GNSS (Global Navigation Satellite Systems), based on the SSR (State Space Representation) concept. One challenge for the fast convergence of PPP-RTK solutions in real-time applications is the mitigation of atmospheric effects (troposphere and ionosphere). Thus, using atmospheric models, PPP solutions can achieve accurate positions and shortened initialisation time. Such performance depends on the topology of permanent station networks and atmospheric conditions. The main objective of this contribution is to study the PPP-RTK and the optimised infrastructure in terms of costs and benefits to realise the method using atmospheric corrections.

利用自适应约束推导PPP-RTK电离层和对流层SSR校正的一种替代方法

PPP-RTK（精确点定位-实时运动学）是GNSS（全球导航卫星系统）基于SSR（状态空间表示）概念的一种定位方法。PPP-RTK解决方案在实时应用中快速收敛的一个挑战是减轻大气影响（对流层和电离层）。因此，使用大气模型，PPP解决方案可以实现准确的位置和缩短初始化时间。这种性能取决于永久站网络的拓扑结构和大气条件。该贡献的主要目标是从成本和效益方面研究PPP-RTK和优化的基础设施，以实现使用大气校正的方法。

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.
