Abstract
  In this paper a practical method for tropospheric effects on GPS derived coordinates in absolute mode is presented. GPS observations at the permanent GPS stations can be used as source of information for the modeling. The developed model is a time-dependent model and as such differs from usual tropospheric ...  Read More

تخمین جهانی پتانسیل ژئوئید، توپوگرافی سطح دریا و ژئوئید بر اساس مشاهدات ارتفاع‌سنجی ماهواره‌ای

Abstract
  Using satellite altimetry derived mean sea level (MSL), geopotential coefficients in terms of ellipsoidal harmonics from recent satellite gravimetry missions, gravity potential values over a grid consisting of 33,486 points at global sea areas are computed and the mean value of the gravity potential ...  Read More
