Comprehensive Analyses of PPP-B2b Performance in China and Surrounding Areas
Remote Sensing, 2022 BeiDou Global Navigation Satellite System (BDS-3) provides a regional Precise Point Positioning (PPP) service, called PPP-B2b, for users in China and surrounding areas through B2b signal transmitted from its three geostationary earth orbit (GEO ...

International Journal of Aerospace Engineering, Volume 2024, Issue 1, 2024.Under most circumstances, the current studies related to precision orbit determination (POD) using intersatellite link (ISL) measurements are limited to ISL ranging components. In this article, we would like to discuss the idea of jointly using the GNSS observations and ISL ranging and orientation measurements of the Tianzhou‐6 (TZ‐6) spacecraft to ...

T‐SPP: Improving GNSS Single‐Point Positioning Performance Using Transformer‐Based Correction
International Journal of Intelligent Systems, Volume 2024, Issue 1, 2024.GNSS (global navigation satellite systems) technology enables high‐precision single‐point positioning (SPP) in open environments. However, the accuracy of GNSS positioning is significantly compromised in complex urban canyons due to signal obstructions and non‐line‐of‐sight propagation errors.

A generalized no-broadcasting theorem [PDF]
Phys. Rev. Lett. 99:240501 (2007), 2007 We prove a generalized version of the no-broadcasting theorem, applicable to essentially \emph{any} nonclassical finite-dimensional probabilistic model satisfying a no-signaling criterion, including ones with ``super-quantum'' correlations. A strengthened version of the quantum no-broadcasting theorem follows, and its proof is significantly simpler ...
