ya i agree.
for us there is more confusion because the sp80/85 heads actually have two phase centers, i think they are for L1 and L2 bands. plus when we send our data away to the NAR CAN post processing service, they also calculate a phase center which last time i checked was slightly different.
showing the data to what we measure would be appreciated.

In the job data, there should be your base station height and what it was measured to, and then the next piece of data is the height relative to antenna phase center. You can see it through expanding your JOB file within Project Explorer. Not sure if you can view it any other way though.
Years ago I had my vendor send through to Trimble, for Trimble RTX post processing returned results, that the field height measurement info be included since it is a quality control check. But those PDFs still come back only showing antenna phase center.

The "From Method" should be Antenna Phase Center. When you start a base, it will take what ever method you used to start the base and convert it to Antenna Phase Center. This is what will be broadcast from the base as part of CMRx or RTCM corrections.

Thank you for all the information and help everyone, That update has solved the issues, I was lead in the wrong direction with my boss. Who seems to think if we never change our TBC software, we never will need to update anything ha.
The last thing I just need to confirm (for my own sanity and My bosses ultimately)
The "From Method" column. If I am measuring to my R10/R12 Lever Extension. Does that column need to say R10/R12 lever extension. Or should it say Antenna Phase center.
again. Thank you all for the help.

i did what florentin said and updated the gps config, there is actually a 25 version now that made it so that i did not have to go in and change that date. (i tried at first and had a hard time because it would not let me store the change with notepad anyways). so this solved the invalid leap seconds that i have had for a bit now. but i still get the phase center when i would rather not have the phase center. i have a screen shot with the same base station and rover on two different days. first day is with survey pro on tsc3. second day is with tsc5 and access 2023 latest version. i think they have a 2024 coming out right about now. also of interest, when i import from survey pro i get a pop up with base information for the survey, including base height and measured to. but with access it just dumps all the data in, with no check in.

Based on the screenshot you have an invalid leap seconds error, and unknown antenna type.
Please follow below steps to correct this issue, in TBC/Support/ Check for updates / Download and install Trimble GPS Configuration Utility.
Invalid leap seconds in TBC | Trimble Business Center
The TBC team have just release an updated GPS Configuration Files Utility to address this issue.

Hello All,
I dont know how best to title this thread, nor how to explain some of this properly so bear with me...
I work with a mineral exploration company based in Canada, we use our Trimble R12i systems, with an RTK survey style to get accurate elevation data, we then merge that data with our instruments that "read" densities of the earth. This elevation data is crucial to our work and I am currently having some issues with at least one of my R12i heads. This may be something in the settings that we have missed, or just dont know about.
I will include some photo examples of what I am coming up against
Our RTK survey style, is set up as a default, to measure to our R10 lever Extension. However we have come across an issue where once the data has been downloaded and imported into TBC, The "Measure to" for the base has changed to "Antenna Phase Center" of its own accord. Upon further investigation in the Vector Spreadsheet, The R12i does not recognize itself as an R12i.... nor that it has been manufactured by Trimble, which then removes the option for "R12 internal" in the "From Type" column.
I can go back through and manually change the data points back to R10 lever extension. But I would like to get to the bottom of why the R12 wont recognize itself or its internal antenna. This may be overthinking on my part.....but like I said this elevation data is CRUCIAL to our survey and will completely invalidate all of our collected data if it is off by more then 5mm to 10mm
Below is a photo of our vector spreadsheet.
If anyone has any suggestions or advice, would be greatly appreciated
Thank you!
