Is there any model out there that has a program to run a calibration baseline and apply the results?
And why not?
I dunno Scott, but if there isn't, there should be!
The last time I did a “serious” “Total Station” traverse, we went to the baseline before and after to fact, and I wrote my own software to reduce/correct the raw observations.

This program doesn't run in your data collector but it is a great program for giving you the results of a calibration run. I have collected all of the data in my data collector and then used it with this calibrate program, it works great.

Carlson's SurvNet has an EDM Calibration program, but input is hand-entered, not read from a data collector file. So Carlson is 50% there. It would take user-pressure to get Carlson to totally automate the collection and processing of the edm calibration process. It would not be a whole lot of work since they have one of the major pieces in place already. The problem is that there is very little push from users for this feature. Not many surveyors regularly go to baselines, and when they do they typically shoot a few distances and compare to the published. They do not go through the actual computation of constant and PPM error, and the resulting statistics. Hand entering the data is not too burdensome. If you understand the program it takes 5-10 minutes to enter the data and get results, while it typically takes a half day between driving, coordinating etc. to collect the data.

I posted this a couple of years ago, it's pretty easy to do it on excel. Here's the least squares solution of a calibration baseline.
