The file IfE20_2132.atx contains Phase Centre Corrections (PCC) for receiver antennas in the ATX format for following frequencies: GPS: GL1C (G01), GL2W (G02) and GL5X (G05), Galileo: EL1X (E01) and EL5X (E05) Following antennas are included in the file:NOV703GGG.R2 NONE12420040 LEIAR25.R3 LEIT08360013 The PCC are estimated using spherical harmonics up to degree and order eight, whereby during the least square adjustment the odd parameters (e.g. a21, b21, a30, ...) are restricted to zero. Please note, that the data is in experimental status and no (!) official calibration product. Thus, it is free for scientific research/use only.
