Space Weather, Volume 24, Issue 3, March 2026.Abstract Solar activity induces ionospheric irregularities that degrade Global Navigation Satellite System (GNSS) performance through amplitude and phase scintillation. Although numerous studies have investigated event‐driven or regional responses, the nonlinear coupling between solar radiation, ionospheric scintillation, and precise point positioning (

Ionospheric Scintillation Activity Over Ilorin, Nigeria
Space Weather, 2018 AbstractScintillation of radio waves in the L‐band frequency is a regular occurrence at the equatorial and auroral regions at night most especially during high solar activity periods. Scintillation is caused by plasma density irregularities, and this could cause loss of lock of Global Navigation Satellite System (GNSS) signals leading to impairment of ...

GNSS ionospheric scintillation studies in Singapore [PDF]
, 2019 Ionospheric scintillation has been a challenge for Global Navigation Satellites System (GNSS) application especially in equatorial region. Ionosphere in around equatorial region is known to have unique characteristic. The existence of horizontal geomagnetic field and eastward electric field in this region caused equatorial ionosphere anomaly (EIA ...

Scintillations during occultations by planets. 1. An approximate theory [PDF]
Scintillations observed during occultations of both stars and spacecraft by planetary atmospheres are discussed theoretically. The effects of severe flattening of the Fresnel zone or source image by defocusing on occultations are presented, along with ...
