1.	Which of the following is true with respect to ionospheric scintillation effects?(a) It causes signal fading(b) Occurs at the equatorial and polar regions(c) Occurs mostly at day(d) Occurs when high solar activity is presentI had been asked this question in an online interview.This intriguing question comes from Atmospheric Effects on Satellite Signals in chapter Satellite Radio Navigation& Inertial Navigation of Avionics
Answer» Right ANSWER is (c) Occurs mostly at day Best EXPLANATION: Ionospheric scintillation causes signal fading and effects in the equatorial and the Polar Regions. Strong scintillation effects are rare LOCALIZED at certain times during the NIGHT, and usually occurs during periods of high SOLAR activity.
