Survey on signal processing for GNSS under ionospheric scintillation: Detection, monitoring, and mitigation

Abstract: Ionospheric scintillation is the physical phenomena affecting radio waves coming from the space through the ionosphere. Such disturbance is caused by ionospheric electron‐density irregularities and is a major threat in Global Navigation Satellite Systems (GNSS). From a signal‐processing perspective, scintillation is one of the most challenging propagation scenarios, particularly affecting high‐precision GNSS receivers and safety critical applications where accuracy, availability, continuity, and integrity are … Show more

“…These changing effects challenge the synchronization capability of the tracking stage [1,7]. Since traditional tracking lacks resilience due to its fixed configuration, there has been significant research towards robust tracking solutions to solve this problem [8,9]. However, there is still ample investigation to find the optimal technique in terms of performance and complexity [7].…”

“…The latter arises due to the thermal noise, the oscillator phase noise, quantization noise, signal interference, and other noise sources [ 8 ]. Multi-path, fading effects, and scintillation also shape the noise and introduce biases [ 9 ]. The loop bandwidth of conventional STLs presents a trade-off between the ability to stay locked in the presence of dynamics and the amount of filtered noise to achieve better precision [ 6 ].…”

“…in equatorial and high-latitude regions [1]. The equatorial region experiences the most significant activity, with severe scintillation resulting in rapid amplitude and phase variations with deep amplitude fades for short periods, depending on factors such as solar activity, geomagnetic activity, latitude, carrier frequency, and daytime [2].…”

Thereby the detection, monitoring, and mitigation of ionospheric scintillation effects in a GNSS receiver are challenging from the signal processing perspective [1].…”
