  • Enter your lat/long + satellite longitude.
  • Use compass + inclinometer to aim.

About this calculator

Geostationary satellites orbit at 35,786 km equatorial altitude. From any point on Earth: aim dish at specific azimuth (compass bearing) + elevation (angle above horizon). Approximation here ignores Earth's ellipsoid + atmospheric refraction (within 0.5°). Below 5° elevation: signal often blocked by terrain/trees. Add magnetic declination to true azimuth for compass bearing. Source: ITU-R recommendations.

Frequently asked

GEO orbit?+
35,786 km above equator. Period 23.93 hr (sidereal day). Stays "fixed" relative to Earth.
Common satellites?+
DirecTV: 99°W + 101°W + 103°W + others. Dish Network: 110°W, 119°W, 129°W.
Magnetic vs. true north?+
Compass shows magnetic. True azimuth needs declination correction (varies by location, NOAA model).
Obstructions?+
Below 20° elevation: trees/buildings often block. Site survey before installation.
Polar mount?+
Single-axis dish that can track multiple GEO satellites along the arc by rotation only.
