The use of PSD analysis on BeiDou and GPS 10Hz dynamic data for change detection [PDF]

open access: yes, 2016
This paper examines the use of GPS and BeiDou data to measure the movements of two oscillating platforms in a series of field experiments. Data were gathered from a variety of GNSS receivers at a rate of 10Hz, and processed in an on the fly manner ...

Analysis of multi-constellation GNSS signal quality [PDF]

open access: yes, 2016
The code pseudo-ranges and phase pseudo-ranges are affected by the systematic errors or biases and random noises. These errors can be classified into three groups, satellite related errors, propagation-medium related errors and receiver related errors ...

Estimation of BDS pseudorange biases with high temporal resolution: feasibility, affecting factors, and necessity

open access: yesSatellite Navigation, 2023
A common practice adopted for the pseudorange bias estimation and calibration assumes that Global Navigation Satellite System satellite-dependent pseudorange biases vary gently over time. Whereupon satellite pseudorange biases are routinely estimated and
