Enhanced GNSS Reliability on High-Dynamic Platforms: A Comparative Study of Multi-Frequency, Multi-Constellation Signals in Jamming Environments [PDF]
Sensors, 2023 The global navigation satellite system (GNSS) signals are vulnerable to disruption sources, such as signal jamming. This, in turn, can cause severe degradation or discontinuities of the GNSS-based position, navigation, and timing services.

Analysis of multi-constellation GNSS signal quality [PDF]
The International Technical Meeting of the The Institute of Navigation, 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 ...
