The position of the sun can be used to more precisely locate a satellite's azimuth than a compass.

(i) Go to the Online Satellite Calculations webpage and select your location.

(ii) Select the required satellite.

(iii) Read off the calculated local sun pass time.

(iv) If you point your dish in the direction of the sun at the time calculated, you will be very close to the exact location.

(v) Remember that the sun's position changes throughout the year with the seasons and the sun pass times for different satellites will change accordingly. Therefore you must do the calculation immediately prior to aligning the dish. Don't rely on a sun pass calculation you did 2 months ago - it will be wrong!

Note: The sun's elevation is usually different to that of the satellite i.e. the sun is higher than the satellite during summer and lower during winter. Only in February/March or September/October does the sun track the Clarke Belt closely for both azimuth and elevation. For that reason, the satellite's elevation and line-of-sight can instead be checked using a protractor and a plumb line.
