Feature Article: Integrity monitoring scheme for single-epoch GNSS PPP-RTK positioning

New Content Item (1)
With the increasing demands of high-accuracy autonomous navigation for unmanned ground and aerial vehicles, the integrity monitoring method of Precise Point Positioning (PPP) has become an essential requirement. Nevertheless, there are still many difficulties in the integrity monitoring method for the high-accuracy Global Navigation Satellite Systems (GNSS) positioning. The main difficulties are caused by using the measurements of multiple epochs in PPP. Based on the baseline Multiple Hypothesis Solution Separation (MHSS) Advanced Receiver Autonomous Integrity Monitoring (ARAIM) algorithm, this paper discusses the feasibility of the pseudorange-based baseline ARAIM method on the single-epoch PPP based on Real-Time Kinematic (RTK) networks (PPP-RTK) framework to overcome these difficulties. Results present that the method based on the single-epoch PPP-RTK framework may achieve high availability and tight bounds for estimating protection levels. This also shows the potential of this method in autonomous navigation in the future.

New Content Item

Yuanxi Yang serves as Academician of the Chinese Academy of Sciences for his lifelong contributions to navigation, geodetic science and engineering. Currently, he is Professor of Geodesy and Navigation at Xi’an Research Institute of Surveying and Mapping and serves at China National Administration of GNSS and Application (CNAGA). He is also Head of State Key Laboratory Of Geo-information Engineering, adjunct professor and PhD Tutor in Beihang University.
He acted as deputy chief designer of China’s BeiDou Navigation Satellite System (BDS), and has been a leading member of BDS advisory board since its inception in 2010. He originally developed the Robust Parameter Estimation for Geodetic Correlated Observations and adaptive navigation and kinematic positioning. He is credited with improving the design of the interlink between BeiDou satellites, the establishment of the Chinese Geodetic Coordinate System, the creation of the Chinese National GPS Control Network, and is a prominent proponent of interoperability between BeiDou and other GNSSs.
" The continuous development of global and regional satellite navigation systems provides an important basis for the integrated applications of multi-satellite navigation. The Journal aims to disseminate the latest achievements of satellite navigation, discuss different academic views and promote the progress of technology and applications. I hope Satellite Navigation will build an academic exchange platform for all researchers." Said Prof. Yuanxi Yang.
