Formula for Calculating The Azimuth Based On Your Location Using the FastAlign 5100Pro® Satellite Meter

It's easy to calculate your true azimuth using the azimuth reading on the FastAlign 5100Pro®.  For most satellite technicians, you will need to remember only one of the four formulas that pertains to you, based on your geographical market and location and if you install satellite systems on 1 continent.

When the meter displays your azimuth, use one of the following basic formulas to calculate your true azimuth.

South East Calculation 

If the curser is pointing to SE, as displayed below, you take 180° and subtract the azimuth reading on the meter.  This will give you your true desired satellites azimuth and it's where your satellite dish needs to be pointing to based on your compass.

 

Formula: 180° -  Meter Reading = Azimuth

 

Example:  If you are located in the Eastern hemisphere at 118°E and 34°N, your meter azimuth reading will display 59° for the satellite located at 162°E.  You would subtract your meter reading of 59° from 180° and your azimuth would be 121°.

 

 



North East Calculation 

If the curser is pointing to NE, as displayed below, your azimuth reading on the meter is the true azimuth of your targeted satellite. 

 

Formula: 0° +  Meter Reading = Azimuth

 

Example:  If you are located in the south west Australia at 118°E and 34°S, your meter azimuth reading will display 33° for the satellite located at 138°E.  This 33° would be the actual azimuth of your targeted satellite, as you would not add or subtract anything. 



South West Calculation 

If the curser is pointing to SW, as displayed below, you take 180° and add the azimuth reading on the meter.  This will give you your true desired satellites azimuth and it's where your satellite dish needs to be pointing to based on your compass.

 

Formula: 180° +  Meter Reading = Azimuth

 

Example:  If you are located in the Western hemisphere at 85°E and 34°N (Marietta, GA USA), your meter azimuth reading will display 20° for the satellite located at 97°W.  You would add your meter reading of 20° to 180° and the azimuth of your targeted satellite would be 200°.


North West Calculation

If the curser is pointing to NW, as displayed below, you take 360° and subtract the azimuth reading on the meter.  This will give you your true desired satellites azimuth and it's where your satellite dish needs to be pointing to based on your compass.

 

Formula: 360° -  Meter Reading = Azimuth

 

Example:  If you are located in the Western hemisphere at 70°E and 45°S, your meter azimuth reading will display 35° for the satellite located at 97°W.  You would subtract your meter reading of 35° from 360° and your azimuth would be 325°.
