What is my true SOUTH satellite?

[Admin]

We get this question quite often.

Basically your True South satellite is the one that has the same Longitude as your location or the closest one to your location.

For example, if you live in New York, NY, then your Longitude is 74 W. Taking a look at the satellites list here http://sadoun.com/Sat/Satellites/Satellite-List.htm you will find that SBS6 is the satellite located at 74 W. So that is your True South satellite.

Then based on that, you should consider the magnetic deviation for that location when looking at the compass to establish True South direction for your motorized dish. The Magnetic deviation for New York is +14. That means the True South direction should be equal to 180 +14 = 194 degrees on the compass.

Is the sbs6 satellite at 74 degree west still functionning since it hasnt been tracked since 1999 and its free.I cant track it from montreal

yea, its still there check out

http://www.lyngsat.com/sbs6.html

theres onlyt a few channels they area active all the time

Thank you for your answer I will try asap .

I am trying to locate 91' for Nimig 1 . I live in Los Angeles but can't figuare out how to find the 91' for this sat. Can you assist me!!!

I assume no motor, but just poitint the dish at the bird...
I used los angels as the starting spot on Sadouns calculator page:
http://www.sadoun.com/Sat/Installati...Calculator.htm

The elevation for the dish (up and down movement) will be about 40 degrees.
The azimuth is calculating by taking the raw number given (137.4) and SUBTRACTING your magnetic deviation number (it seems as though its 14 for your town) from that raw number, so with a good COMPASS line up the LNB arm of the dish to 123.4 (the "side to side" movement).
You will also need to "twist" the LNB to the left so the bottom (where the cable comes out) is at 8:00 o'clock on an imaginary clock positon as you LOOK AT THE DISH from the perspective of the satellite looking DOWN at the dish (not from behind looking up.)

These steps should get you close. Have a small Tv connected near the dish, adjust for best signal once you adjust the above locations in small increments till you find the some quality reading on the antenna setup scrren.

Make sure you are tuning with an "active" transponder to observie a reading. I have no idea what they are on that sat.
Also, I think this sat requires a "Circlular" LNB so the skew wont matter too much...

Good luck.

Hi admin,
where and how do you find the value + 14 in that example (New York) ?
My longitude is 121.8 W, very close to Echo 9 (my location San Jose, California 95132), could you help please
Thanks

Take a look at the map on this page: http://sadoun.com/Sat/Installation/S...Calculator.htm

Check which line crosses your town (or close to it) and ADD or Subtract based on your location.

my longtitude is 85 and amc9 i believe is my true south satellite,so now how do i figure out if i have to add or subtract 14 thanks,i will appreciate the help

[stockgurubear]

You don't always add or subtract 14 degrees. Depending on where you live, you add or subtract the value for your area. See the map at:

http://www.sadoun.com/Sat/Installati...Calculator.htm

I am on the west coast, so you can see the 15 that is marked in that region. So I subtract 15 from 180 making it 165. Do the same for your part of the country

I needed to locate the correct Azimuth setting for my WaveFrontier Toroidal dish and I found this the be the best way. Aligning one of these so it can track properly can be a bear and I had it almost perfect the first time.
First I made sure my pole was plumb. Then I set the skew to 0 degrees and checked it with my level.
The T90 has 2 small holes drilled into the bottom of the main and subreflector. They seem to be exactly located at the midpoints. They are perfect to use for alignment. I hung a plumb weight on a line from both holes.
Next, knowing what my desired Azimuth was from the calculation given me by Wavefrontier (must be registered) I went to the US Naval observatory site:

http://aa.usno.navy.mil/data/docs/AltAz.html

I entered the current day, date and my location and asked for a solar chart with 1 minute intervals. I checked the chart for the time of day when the sun was closest to my desired azimuth. I then synchronized my watch to "atomic" wall clock.
Before the calculated time, I took a plain white card with me to the dish, and did a rough alignment. The dish is pointed at the sun when the shadows of the two plumb lines coincide on the card. When the exact time came, I double checked the alignment and tightened down the dish.
The rest was simple. I set my elevation and skew according to the calculations provided by WaveFrontier and I was nearly perfectly tracking the sats.
I'm planning on doing a motorized dish at some point, and I'll try to figure out how to use the sun to align that too I imagine.

Can somebody tell me when i have to add or subtract?

My longitude is 120.27w. Would it matter if I used EchoStar 7 or EchoStar 9 for my south satellite?

[dapack5]

my latitude is 26.615302n and my longitude is 81.61046w:
my wuestion is does this make nimiq2 my southern most satellite at 82 degrees?
here's why i'm asking:
if i get good strong signal/quality readings on galaxy10 then i lose all signall on hispasat D at 30 degrees west! and vice versa, i am using an sg 2100 htoh motor and a fortecstar .90m dish. what could be my main problem with this install? plumb/elevation/azimuth?

sg2100 manual says that if my lattitude is 26 then my elevation angle is 64 and that's where i have it set to on the motor bracket do i subtract the 4.377 angle from anything there or what?

thanks in advance

[starman]

Nimiq 2 is your southern most satellite. The sg-2100 has a latitude scale on one side and an elevation scale on the other...at least mine does. Set the 26(your latitude) on the latitude scale side, on the other side it will be close to 64.. The 4.377 angle you mentioned is probably your declination. With a sg-2100 motor you need to subtract your declination from the motor shaft angle. The shaft angle is 30 degrees, so 30-4.377=25.6. so you need to set the elevation on the dish scale, not the motor scale to 25.6. You said you can get galaxy 10 but not Hispasat, there is a lot of territory between the two, can you get other satellites, just not Hispasat?

yes i can get pas9,amazonas,IA-5,amc3,T-6, and several others,but,quality on T-6 PBS channels is only around 68% and breaking up too,IA-5 i have a sub for inxworld and quality isn't good on that sat either around 70%, i'm using the invacom circular/linear lnb that i purchased from sadoun and if i get a 95 to 97% quality signal on 82 ( just to check for proper tracking ) then 119 is only around 72 to 76 % and i totally lose G10 and still wouldn't have hispasat either. today i got hispasat @ 97% quality while trying to adjust the dish,but,had nothing on G10 or 119.

My latitude is 28.0 N , Longtitude is 81.7 W , my true south compass reading is 185 S and my true south satellite is Nimiq2 at 82.0 W.... Is this correct?
Im using HH90 with a fortec classic NA sat receiver. How about motor and dish elevation, whats the difference and how to adjust it?

[rainman]

yes that would be correct.

[rainman]

sorry about the short reply above was having internet problems.
you are correct on your south sat.
motor elevation should be the same as your lat.
