Ionosphere and troposphere delays
WebThe total delay suffered by a radio wave propagating through the ionosphere depends both on the frequency of the radio wave and the TEC between the transmitter and the receiver. At some frequencies the radio waves pass through the ionosphere. At other frequencies, the waves are reflected by the ionosphere. Web21 jul. 2024 · While radio signals travel with the velocity of light in the outer space, their propagation in the ionosphere and troposphere is slower. In the ionosphere (consisting of layers) in a height of 80 – 400 km a large …

Webof satellite ephemerides, effects of ionosphere and troposphere are almost eliminated by forming DD (double-difference) measurement equations. With a medium length baseline under 100 km, in particular ionosphere effects are hard to be canceled by DD. In this case, dual-frequency measurements are often used to eliminate the ionosphere effects.
