Ionospheric or tropospheric scintillation

Web10 mei 2002 · [19] Scintillation is predominantly a nighttime phenomenon in the equatorial region occurring for more than 40% of the year during the 2000–0200 local time period [Basu et al., 1976]. It also shows a strong seasonal dependence with a pronounced minimum at the southern solstice and relatively high scintillation activity at the northern … WebINTRODUCTION In the past_ the monitoring of ionospheric scintillation using satellite radiated signals has primarily been on an experimental basis. Specially designed satellites have been launched for that purpose [2] .In more recent years, the signals radiated from the GPS satellites have been used with success, but mostly experimental [3. 4].
