TLDR
The next generation of positioning models for positioning and data processing will depend on the design of the satellite itself, as well as on the satellite orbits it is placed in.Citations

Improvement of orbit determination accuracy for Beidou Navigation Satellite System with Two-way Satellite Time Frequency Transfer
Chengpan Tang,Xiaogong Hu,Shanshi Zhou,Rui Guo,Feng He,Li Liu,LingFeng Zhu,Xiaojie Li,Shan Wu,Gang Zhao,Yang Yu,Yueling Cao +11 more
TL;DR: In order to improve the orbit determination accuracy for BDS, a new orbit determination strategy is proposed, in which the satellite clock measurements from TWSTFT are fixed as known values, and only the orbits of the satellites are solved.

PPP-RTK and inter-system biases: the ISB look-up table as a means to support multi-system PPP-RTK
TL;DR: An ISB look-up table is proposed that allows users to search the table for a network receiver of their own type and select the corresponding ISBs, thus effectively realizing their own ISB-corrected user model and the number of integer-estimable user ambiguities is maximized.

LoRa-based localization systems for noisy outdoor environment
TL;DR: A winner selection strategy to select a winner from the traditional localization algorithm and the two new algorithms to minimize localization errors are developed, which can significantly improve localization accuracy.

The performance comparison between GPs and BeiDou‐2/compass: A perspective from Asia
TL;DR: The main objective of this paper is to study the performance of BeiDou‐2/Compass comparied to GPS in the greater Asia region; and to explore whether the combination of Bei Dou‐2 /Compass with GPS would yield performance improvements in this region.

Ionospheric slab thickness - Analysis, modelling and monitoring
Stanimir Stankov,René Warnant +1 more
TL;DR: In this paper, a review of the climatological and storm-time behavior of the ionospheric slab thickness is presented based on long-time observations at a European mid-latitude site, Dourbes (50.1N, 04.6E), and on published results from other studies.
