just click the options button in rtkpost and there you can select the type of tropospheric correction, which can be set to estimate the ZTD.

chapter 3.5 of the manual contains all configuration options for rtkpost if you have further questions.

@Sascha, thanks a lot! I did the following in the Option, Setting1, I will like to know if Im on the right path:

Positioning Mode: PPP Static

Frequencies/Filter Type: L1+2/Forward

Elevation Mask/SNR Mask (dBHz): 15

Rec Dynamics/Earth Tides Correction: OFF/OFF

Ionospheric Correction: Broadcast

Tropospheric Correction: Estimate ZTD

Satellite Ephemeris/Clock: Broadcast

Then I checked the following: Sat PCV

                                                       Rec PCV

                                                       RAIM FDE

                                                        GPS

depending in the accuracy you want to reach, i would consider using precise satellite ephemerides from IGS and maybe a more accurate ionosphere model if you have one. maybe also earth tidal corrections depending on the receiver position, but otherwise i think the results should be good!

Just wondering which output variable gives the ZTD? I have tried the above mentioned setting in RTKLIB with a sample file, but the output seems to provide only the position information. Can anybody give further details?

Hello,

I also want to know how to output ZTD values from RTKLib? if you got the answer, please tell me, thanks so much!

Hello,

I also want to know which output gives the ZTD. Anyone can help answer me?

Hi,

If you are using RTKLIB, you may find information about ZTD in output files of RTKPOST. You should set Tropo Corretions as "estimate ZTD" and information about ZTD will be included in "*.stat" file in $TROP line. For more information please look into RTKLIB manual, "File Formats" section.

Hello,

If i execute rtkpost to get ztd value, there no .stat file generated. Anyone can help me?

You need to configure it in *.conf file or setup through "Options" in rtkpost GUI (as on attached figure).

Im trying to get the ZTD estimates using 2 CORS station through RTKLIB, does anyone know how the seetings for this?
