The program "Satellite Antenna Alignment" is used to calculate
the angles necessary for installing satellite dishes. The main difference
from similar software is the possibility to calculate the position
for all satellites at once. Thus, you get a clear picture about
what satellites can be physically visible from the location where
the dish will be installed. It should be kept in mind that the program
makes a purely theoretical calculation according to formulas and
in real circumstances a lot of additional factors should be taken
into account when a satellite dish is installed. These factors include
various obstacles (buildings, trees), the landscape, the altitude,
transponder orientation, polarization, etc. Nevertheless, this program
will allow you to evaluate the position quite precisely. The calculation
can be saved to a text file, copied to the Windows clipboard or
printed out at once. It is possible to save the list of locations
for which the calculation is done. Later on, you will not have to
enter the coordinates of these locations again. Just select them
from the table.
This is an evaluation version "Satellite Antenna Alignment" that you may try and distribute free of charge for private non-commercial usage, as long as you need. For regular or commercial usage you are required to order the full version. You will receive license code (via e-mail) that enable full functionality without nag screen and other restrictions.

You should start working with the program from
entering the geographical coordinates of the location where you
are going to install the satellite dish. Enter your coordinates
in the "Site location" box. The high latitude is specified
with the "N"
char, the low latitude is specified with the the "S"
char. Similarly, the eastern longitude is with the "E"
char, while the western longitude is with the "W" char.
After all the coordinates are entered, you will see the calculation
for all satellites at once in the table to the left. Their azimuth
and elevation are calculated. Azimuth is the direction to the satellite
in degrees from the clockwise direction to the north. Elevation
is an angle (measured in degrees) between the direction of the signal
from the satellite and a tangential plane to the Earth surface in
the location. If the elevation is negative, the satellite is below
the horizon and it is impossible to receive signals from it in principle.
Thus, the satellites whose elevation is a positive value are theoretically
visible from your location. If you know the azimuth, you can quickly
find the direction to the satellite and see what obstacles (neighboring
houses, trees) there are in the way of the signal from the satellite
to your dish.
As it was mentioned above, the program uses absolute
values and calculates everything according to formulas. Thus, the
calculated azimuth is an angle from the true north and not from
what your compass may show because a compass is a really unstable
thing, especially in a city. It is better to orient it by the sun
Additionally, the program has a mechanism for calculating
the azimuth of the sun and you can do everything without a compass
now! The azimuth is calculated for the location the coordinates
of which you specified for calculating the azimuths of satellites.
You can specify the date (the current date is taken by default)
and calculate how the sun moves with a one minute discontinuity.
The calculation results are displayed in the table to the left.
Both the azimuth and the elevation are calculated for the sun for
the current moment of time. Thus, you can install the satellite
dish without a compass at all. First, find the azimuth of the satellite
you need. Then calculate the azimuth of the sun for the day on which
you are going to install the dish. Find the azimuth of the sun that
is most close to the azimuth to the satellite and you will see the
time (and date) when the sun will be in the same direction where
the satellite is. Turn the dish to the sun at the specified moment
of time, the azimuth of the sun coincides with the azimuth of the
satellite at this moment. Or just note this direction and install
the dish later. Remember to specify your time zone for calculation
(Moscow: +3 GMT). The program also calculates the azimuths of the
sunrise and sunset, as well as the time and elevation when the sun
is exactly in the south. Home & Pro hdmi cables by Cmple.
The program draws a simple diagram representing
the four directions. The yellow sector is daytime, its eastern part
is sunrise and its western part is sunset. The same diagram can
be used to schematically represent the direction to the satellite
you need. Select the satellite from the drop-down list and the red
line will show the direction to it (azimuth). If the elevation is
negative, no red line is drawn (the satellite is not visible).
Offset satellite dishes are widely spread now.
When such a dish is completely vertical, it already has some
elevation (~20-25 degrees). You can enter the size of your offset
dish (height and width) and the program will calculate the exact
elevation for this dish. The calculation is done only for dishes
whose height is greater than width. Enter the size of the dish in
millimeters. Here you will see the elevation to the selected
satellite and the angle you should actually install you dish at (in
degrees from the Earth surface).
Altitude is the angle up from the horizon. Zero degrees altitude means
exactly on your local horizon, and 90 degrees is "straight up".
Hence, "directly underfoot" is -90 degrees altitude.
Azimuth is the angle along the horizon, with zero degrees corresponding
to North, and increasing in a clockwise fashion. Thus, 90 degrees
is East, 180 degrees is South, and 270 degrees is West. Using these
two angles, one can describe the apparent position of an object
(such as the Sun at a given time).
