The objectives of this study are, through field testing and analytical analysis, to: validate the use of the free-space path model in link budget calculations; determine the actual link margin values that should be used in the link budget calculations;determine the fading levels which must be accounted for in link budget calculations;determine the maximum GPS radiosonde interference level that can be tolerated by a GPS radiosonde.
