This diagram shows the satellite data from the point of view of a receiving station as a function of time. Slant means that the microwave signal of the satellite propagates diagonally through the atmosphere and hits the receiver at a certain angle.
Azimuth φ: The angle of the satellite to the North Pole with respect to the horizontal plane in degrees.
Elevation ε: The angle from the horizontal plane up to the satellite in degrees.
Delay (STD): Slant Time Delay. The signal travel time delay in meters.
Delay Zenit (ZTD): Zenithal Time Delay. The signal travel time delay in meters, calculated for a virtual position at the zenith.
Select a station, a time period and a satellite. The preparation of the data may take a moment. The station selection is filtered to a few stations that are important for the Tryat project. Check the box 'All stations' to select the other stations.
Times in UTC. To convert to Central European Summer Time, you have to add two hours. For Central European Time (in winter) add one hour.
