Satellite Phase Center Offset: Correct satellite PCOs with the selected ANTEX File
Satellite Phase Center Variations: Correct satellite PCVs with the selected ANTEX File
Receiver Phase Center Offset: Correct receiver PCOs with the selected ANTEX File
Receiver Phase Center Variations: Correct receiver PCVs with the selected ANTEX File
Antenna Reference Point Correction: Correct the antenna reference point. Therefore, the antenna offset of the RINEX header is used.
Group Delay Variations: Correct GDVs (e.g., BeiDou)
Phase Wind-Up Correction: Correct Phase Wind-Up [Wu et al., 1993]
Eclipse Condition: If enabled, raPPPid excludes satellites during the processing in the Earth's shadow. Therefore, a simple cylinder model is used. When using an ORBEX file, you might not use this option due to the availability of the satellite attitude.
Solid Tides Correction: Correct solid Earth tides [Petit and Luzum, 2010]
Ocean Loading: Correct for the ocean loading effect, which is only possible for stations having coefficients from http://holt.oso.chalmers.se/loading/index.html in the file OceanLoading.blq (located in the DATA folder, raPPPid/DATA/OceanLoading.blq). Otherwise, no correction for ocean loading correction is applied. To correct for ocean loading, the file 'OceanLoading.blq' in the DATA folder needs to contain the 4-digit station name and the coefficient from http://holt.oso.chalmers.se/loading/. To add a station, go to the mentioned website. Create the coefficients with the following settings: the GOT4.7 model, vertical and horizontal displacements, elastic Green functions, and BLQ format. After you have retrieved the coefficients, add them into 'OceanLoading.blq'. The 4-digit station name in the RINEX file's header and OceanLoading.blq must match. Otherwise, no or wrong coefficients are extracted from the blq-file.
Polar Tides: Correct for the rotational deformation due to polar motion. If enabled, raPPPid downloads the *.erp file corresponding to the selected precise orbit/clock product (e.g., IGS final or CODE MGEX). Currently, this correction can not be applied when manually selecting these satellite products. Please note that the model of the mean pole has to be defined correctly (consistent with the satellite product, variable DEF.ctpm, default = ‘cubic’).

raPPPid automatically checks the satellite orbit file (e.g., sp3) for the coordinate system and tries to apply the corresponding ANTEX file.
Use existing igsXX.atx: Use the version of ANTEX file currently available in \DATA\ANTEX. If igsXX.atx is not available, raPPPid downloads it.
Download current igsXX.atx: Download the newest version of ANTEX file, for example, when the igsXX.atx was updated (check IGSMAIL).
Manual choice: Select the ANTEX file manually (e.g., M20.atx for CODE MGEX PPP-AR)
MyAntex.atx: Add your own PCO and PCV corrections into a file called MyAntex.atx located in raPPPid\DATA\ANTEX. The corrections included in this file (raPPPid\DATA\ANTEX\myAntex.atx) are then used to correct the receiver antenna phase center offsets and variations. raPPPid will check if there are suitable corrections before the processing starts. Make sure that the antenna name in the RINEX file header (ANT # / TYPE) corresponds to the name in myAntex.atx (TYPE / SERIAL NO) and that the formatting is correct (e.g., the antenna name is placed centered in the RINEX header). Note that myAntex.atx is only used for receiver antenna corrections. For the satellite phase center offsets and variations the ANTEX file specified in the GUI is used.
