What geoid are you using for land surveying  

We in Belgium are using the hBG18.

Canadian geoids

HTv2.0 CGVD28:78 is the most common in Ontario with a transition to CGVD2013.

Integration of NRCan's PPP tool would be much appreciated.  You could also take all the geoids and integrate GPS*H to convert ellipsoidal heights to ortho.

Automation of PPP and PPK would give a large advantage.  Examples would be the following:

-at the end of the day, the submission of RINEX to NRCAN is automated (the email method is the most foolproof--desktop app is buggy)

-you have heavy tree cover and cannot get a consistent fix.  Set up the rover for 15 minutes logging PPK to post-process it vs static and/or intermittent RTK shots

-time-tagging ( https://ig8g.com/out/faq/iG8_TimeTagging_001.pdf )

Cheers.

Thanks @jaccen I will check your links.
