This calculator determines the azimuth and elevation angle from your location to another point on Earth or to a satellite subpoint.

Azimuth is the direction to point your antenna, measured in degrees clockwise from true north. Elevation is the angle above the horizon to aim your antenna.

For satellite tracking, enter the sub-satellite point and the satellite’s altitude. Some typical altitudes:

• LEO (e.g. ISS, AO-91): 400–600 km
• MEO (e.g. GPS): ~20,000 km
• GEO (e.g. weather/TV): 35,786 km
