Western Hemisphere/Eastern Hemisphere/Interesting Links

SITE SEARCH ENGINE: This is a large site - with over 170 web pages, 500 images and 2000 source and cross reference links - it has much good info buried deep within. Enter into search engine satellite keywords or words of your satellite interest and it will display a page of hyperlink results for content of this site. We hope it assists to save time while browsing. HINT: Look thru intro paragraph below for general idea of site content, then enter satellite keywords into search engine.

Yes, we know dish size can be calculated using formulae with G/T, C/N, EIRP, noise figures, equipment gain, rain fade factors, slant path values, etc., but let's use comparative analysis to see what size satellite antenna you need because it is fast and visual. However, if you want a link budget equation, go below, you will like it. (page notes)

Choose your footprint region of interest and peruse the links; they are arranged per geographic area, not per satellite, to provide an overview of what size dish is best for satellite beams into your region.

Go to
relative dish size charts to see eirp vs. antenna diameter charts (very good, very useful).

Go to
site calculation for links to global azimuth/elevation, latitude/longitude, magnetic deviation calculation tables and charts and polar mount dish adjustment guidelines including general overview of prime focus systems/choosing a dish, and discussion on dish formulae, LNB/feedhorn types, f/d and scalar settings, cabling/connectors/actuator/servo wiring, ground mount/pad mount installation, ground rod/surge protection, waterproofing, wind loading, rain fade/free space loss, earth thermal noise, terrestrial interference and solar outage. Don't forget the obstacle page for tips on choosing the right location for your system.

Check out the
case history example using the link budget equation. For detailed EIRP footprints to input into link budgets go to Western Hemisphere or Eastern Hemisphere.

To check the location of your country of interest in respect to neighboring countries go to these geo-political maps: Africa, Asia/Australia, (Middle East, Mediterranean, Asian Russia), Europe/Russia, North/South/Central America and go to worldwide TV standards to see the specific NTSC, PAL and Secam layout per country, their voltage requirement and TV frequency/channel assignments.

And for a good general discussion of orbit types check out these links:
geostationary, low earth orbit, medium earth orbit, highly elliptical orbit, polar orbit and sun synchronous orbit with example applications for each one and a brief satellite history.

Page Notes: Two important things to remember:(1)Satellites seen at a particular location are not necessarily
all satellites in orbit above that location--side by side satellites, in orbit, often as not have their beams directed to
different global regions; and (2)within a satellite, the beams of its transponders may be directed to different global
regions so that programming seen in one country from that satellite is different than programming seen in another
country from the same satellite. For these reasons, use the Western Hemisphere
/Eastern Hemisphere charts for
complete geosynchronous satellite details (orbit position, inclination, specs, footprints, coverage, transponder
programming); these regional footprint size charts, on this page, only show the portion of the geo-orbit that can be
seen from a particular location. (return to satellite regional size heading)

Your comments, contributions, and suggestions for related interesting links are all appreciated. The reason we authored this site is to offer as much easy-to-access data as possible, in this subject matter, to the public domain and we hope it will be useful to you. All orbits, sat names, inclinations are as current as my source documents allow.
UPDATED: Links to footprints, specs, programming are checked; orbit positions and inclination are as current as our sources allow; a very few links to press references are still in limbo. Mar-29-01 
We will always be
working on this page as
we add to it whenever we can.
