Nowadays, China BeiDou Navigation Satellite System (BDS) has been developed well and provided global services for highly precise positioning, navigation and timing (PNT) as well as unique short-message communication, particularly global system (BDS-3) with higher precision multi-frequency signals. The precise point positioning (PPP) can provide the precise position, receiver clock, and zenith tropospheric delay (ZTD) with a stand-alone receiver compared to the traditional double differenced relative positioning mode, which has been widely used in PNT, geodesy, meteorology and so on. However, it has a lot of challenges for multi-frequency BDS PPP with different strategies and more unknown parameters. In this paper, the detailed PPP models using the single-, dual-, triple-, and quad-frequency BDS observations are presented and evaluated. Firstly, BDS system and PPP method are introduced. Secondly, the stochastic models of time delay bias (TDB) in BDS-2/BDS-3 PPP including the neglection, random constant, random walk and white noise are presented. Then, three single-frequency, four dual-frequency, four triple-frequency and four quad-frequency BDS PPP models are provided. Finally, the BDS PPP models progress and performances including theoretical comparison of the models, positioning performances, precise time and frequency transfer, ZTD, inter-frequency bias (IFB) and differential code bias (DCB) are presented and evaluated as well as future challenges. The results show that the multi-frequency BDS observations will greatly improve the PPP performances. Read the full article here.
Feature Article: PPP models and performances from single- to quad-frequency BDS observations
Following the rapid economic growth in China over the last 30 years, there is now a strong desire to promote the development and propagation of science and technology for the long-term future. Recognizing the importance of academic journals in disseminating research results and inspiring new research ideas as well as strengthening communication, AIRCAS will sponsor Satellite Navigation as an international platform, providing researchers and engineers in navigation, positioning and timing with a unique opportunity to closely interact and communicate. This journal will not only provide a venue for in-depth scientific exchanges, but also seek to promote research collaborations and exploit international funding sources, especially those involving China.
