Site Calibration in Penmap

    I am working with Catalyst DA2 using the premium corrections facility.

    Undoubtedly, it is a far better device than Catalyst DA1.

    I noticed the following and would like anyone to comment or show me the way around.

    We have a local Augmentation service called AbuDhabi Geodetic Reference System (ADGRS) for short which provides corrections on NTRIP.

    I used DA2 to measure known points with this (ADGRS) correction service and got results close to a few Centimeters in N, E and Z. I have a Site Calibration done and applying the same here.

    I used DA2 to measure the same points with Trimble Correction Hub (TCH). There was a shift of about 70Cm in N and E and about 30m in Z. I suppose the Z variation is coming from the Geoidal undulation and a translation correction for a small are of a few Square Kilometer is in order.

    I tried to do a "Site Calibration" using the TCH and the results were very bad. I attach an Excel file showing these differences.

    Could some one educate me as to how I can get results similar to ADGRS using the TCH.

    Thanks.

    I add the Site Calibration report from Penmap for the same job. See the large variations in observed values with Site Calibration of  22 Jan 2022 in the above Excel file.

    Thanks.

    Dear Giri Muthyas,

    this sounds like a coordinate system issue.
    I'll get in touch with you to analyze the behavior.

    Kind regards
