Dish Alignment Calculator

حاسبة توجيه الطبق

Calculate azimuth, elevation, and LNB skew to point your dish at any satellite.

Satellite

Latitude

Longitude

How it works

Uses standard geostationary look-angle formulas:

Azimuth: atan2(tan(satLon - obsLon), sin(obsLat))
Elevation: atan((cos(diff) * cos(lat) - 0.15127) / sqrt(1 - cos²(diff) * cos²(lat)))
LNB Skew: atan(sin(diff) / tan(lat))

Where diff = satellite longitude - observer longitude, geostationary orbit radius = 42164 km, Earth radius = 6378 km, ratio = 6378/42164 = 0.15127.
