TL;DR: In this paper, it is shown that the observed effects are caused by the resonant interaction of electromagnetic waves with a medium containing Rydberg molecular complexes, which is the main reason for the delay of satellite constellation signals at altitudes of 60 to 110 km.

Modeling and Analysis of BDS-2 and BDS-3 Combined Precise Time and Frequency Transfer Considering Stochastic Models of Inter-System Bias
TL;DR: In this paper, the authors investigated the effect of the inter-system bias (ISB) between regional and global navigation satellite systems (BDS-2 and BDS-3) on precise time and frequency transfer considering four kinds of ISB stochastic models: ignoring ISB, estimating ISB as random constant, random walk process, and white noise process.

Coherent superposition of multi-GNSS wavelet analysis periodogram for sea-level retrieval in GNSS multipath reflectometry
TL;DR: Wavelet analysis is applied to multi-constellation multi-frequency signals to find a method to avoid noise and coherent superposition is used to overlap the intra-track inter-signal instantaneous frequency spectrograms to enhance effective information and to weaken noise.

Baseline length constraint approaches for enhancing GNSS ambiguity resolution: comparative study
TL;DR: In this paper, three different approaches using baseline information (i.e., linearized joint adjustment method, validation method, and constrained LAMBDA method) are comprehensively evaluated through theoretical and experimental analyses, and the results confirm that the combined algorithm achieves better performance that exceeds that of either individual method for a baseline length of tens of meters.
