Hello community!!!

I am yet a novice in the surveying profession who has been using GNSS Solutions from Spectra Precision for post-processing data for less than a year. During a recent discussion with an older and more experienced surveyor, the question of tropospheric correction in commercial baseline processing software packages came up and I was (actually am still are) not knowledgeable about the tropospheric correction model used in GNSS Solutions. I would on this note like to seek any guidance from any member in this community on the following;

  1. What tropospheric correction model (among the available: Hopfield, Sastamonien and Neil) is/are used in the GNSS Solutions network adjustment software package?
  2. Can a user define a correction model or the available model is default?
  3. How do I view the tropospheric correction model information from the software tabs?
