Satellite Slant Range Calculator

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.

Slant Range Calculator

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
