Different aspects of zenith tropospheric delay modelling in GNSS [PDF]

, 2018
Tema magistrske naloge združuje področji geodezije in meteorologije, ki na različne načine omogočata določiti vpliv troposfere na opazovanja GNSS. Troposfera povzroči ukrivljanje signala in zato podaljšanje poti razširjanja signala glede na razširjanje ...

Investigation of the Application of Measured Meteorological Observations in Real-Time Precise Point Positioning

Remote Sensing
Tropospheric delay is the main error source that affects the further improvement of the accuracy of space geodesy. High-precision zenith tropospheric delay (ZTD) can be used as a prior value for precise point positioning (PPP) in global navigation ...

UNIVERSITY OF CALGARY Investigations into the Estimation of Tropospheric Delay And Wet Refractivity Using GPS Measurements

, 2003
The principal error source in the GPS technology is a delay experienced by the GPS signal in propagating through the electrically neutral atmosphere, usually referred to as a tropospheric delay.

Transformation of neill mapping function for GPS tropospheric dela

, 2012
The refraction of the Global Positioning System (GPS) signal as it passes through the neutral atmosphere from the satellite to the earth can be referred as GPS tropospheric delay, which causes longer distance traveled by the signal.
