URGENT Help in cleaning GPS Observation Data in TBC

[roycastanares]

Right now I was tasked in cleaning static GPS observation, e.g. cleaning noise and disabling some satellite observation.

I'm doing well until I can't get fix on some of the baselines,

Then I asked my one of my fellow what are the techniques in cleaning gps observation, they just told me that what they do is trial and error.

Now, I want to ask, if there is another way, like some science in spotting weak satellite observation and cleaning data with precision.

Thanks, hope someone who is expert in this field will be able to give me some hints on how to do this precisely.

BTW.. I am using licensed Trimble Business Center
