This page provides a satellite slant range calculator, useful in satellite communication analysis. The calculator determines the slant range based on these inputs:

  • Altitude (h): The distance of the satellite from the ground station.
  • Earth Radius (B): The distance between the Earth’s center (geocenter) and the ground station.
  • Elevation Angle (ε): The angle of the satellite as seen from the ground station.

The output is the calculated slant range.

Outputs

Here’s an example of how to use the slant range calculator:

INPUTS:

  • Distance between Ground Station & satellite (Altitude), h (Km) = 35786 Km
  • Distance between geocenter & Ground Station, B (Km) = 6378 Km
  • Elevation Angle in degree, ε = 90

Note: The distance between the Geocenter and Satellite (r) is internally calculated as the sum of the altitude (h) and the Earth radius (B).

OUTPUTS:

  • Satellite Slant Range in Km = 35786
