IONO FILMS

• Iono delay/GIVEi broadcast by WAAS, EGNOS, SDCM, GAGAN and MSAS* on 27/04/2013

• Corresponding film of TEC values**

* Data from CNES Regina network** 2 hours IGS IONEX data (jprg files)

2013 Q1-Q2 Main Events

• GEO SWAP

Due to INMARSAT 4F2 NLES band C antenna replacement

• PRN124 (EGNOS TEST) daily outages– Due to ARTEMIS high inclination => Excessive Doppler

for NLES
