In this type of error, the GPS system uses a built-in model that calculates an average amount of delay to
partially correct for this type of
error. The main reason of delay is that the satellite signal slows as it passe through the atmosphere.
Ionosphere and troposphere delays

buildings or large rock surfaces before it reaches the receiver that increases travel time

Also known as ephemeris errors, these are inaccuracies of the
satellite's reported location
Orbital Error
123
