SATCOM tools

Satellite look angle calculator.

Find the azimuth, elevation and polarization skew from any site to any geostationary satellite, and see where the arc sits in your sky.

What each number means.

Azimuth & elevation

Azimuth is the compass direction to the satellite, measured clockwise from true north. Elevation is how far above the horizon to tilt the antenna. Below about 10° elevation, obstructions and rain fade become serious concerns.

Polarization skew

For linear polarization, the feed must be rotated so it lines up with the satellite’s signal. The skew grows the farther the satellite is east or west of your longitude, and the calculator shows which way to turn it.

Slant range

The straight-line distance from your antenna to the satellite. It sets the free-space path loss in a link budget, and it is longest for satellites low on the horizon.
