Abstract:
This invention relates to the troposphere delay produced when the electromagnetic waves from a satellite or astronomical body pass through the troposphere, in particular, it is related to a calculation method of an estimated value of the amount of zenith troposphere delay in real time, and troposphere delay of the satellite positioning signal in the case of positioning using the estimated value of this calculated amount of zenith troposphere delay is related with a correcting method.
