CALCULATING DISH
POINTING PARAMETERS
Once the dish is assembled, and placed in its permanent location,
you may now get the pointing parameters for Azimuth (rotation) Elevation
and Skew (the rotation of the radio equipment).
This is done
with your GPS device and the Satmaster Quickaim pointing program on
your installers laptop.
Sometimes it is a good idea to know what
the GPS reading are for your installation location before an installation.
It simply requires that you have an accurate GPS reading from the
installation location.
The Etrex GPS is normally supplied to all Galileo Installers.
The GPS information can be found at the bottom of the "MARK" screen.
The N stand for "North" and the latitude is 35.26 degrees.
The W stands for "West" and the Longitude is 120.65 degrees.
Locate the Galileo Work Order where you will write the GPS information on the order.
Write down 35.26N (for North)
and 12.65W (for West) in the appropriate boxes.
Now Start the Satmaster Quickaim program from the installers laptop.
Choose "File" then "New" then "Look Angles".
This screen appears that allows you to enter in the appropriate information.
Site name is the name of the customer.
Satellite name is AMC 4 for Galileo North America
Satellite Latitude in this case is 35.26N as is written on your work order.
Satellite Longitude is 101W.
Inclination, Spot Polarization and Offset Focus angle do not need to be filled out. Press "OK" to bring up the screen below:
The only info you are interested in is Elevation, Azimuth Compass Bearing and Polarization offset.
Write these down in the Galileo Work Order.
Note that Dish Skew was a negetive number. This is important to write down for when you are skewing the dish.
