Abstract:
1. A calculation method of determining an estimated value of the amount of zenith troposphere delay comprising: two or more amendment areas which satisfy the same weather condition in a service area is set up by an entrepreneur, in this amendment area, point A and at least one reference point B which offers correction information of the amount of zenith troposphere delay to be used by a user located in point A (user point) are set up, an estimated value ZTD a difference between the estimated value of the amount of zenith troposphere delay in said reference point B and a MOPS model function f subsequently, the difference between the estimated value of the amount of zenith troposphere delay in said reference point B and said model function f said correction information are obtained by the user located in point A (user point), a model function f an estimated value ZTD
