    Default New foxtel satellite

    Hi

    This new foxtel satellite that is being launched in November (going from the advert) for that to work with the current dish configuration for all foxtel users that would have to be placed in the current orbital position as the Optus C1 satellite would it not?

    Reason I ask is that satellite belongs to Optus so does that mean the new satellite belongs to Optus or are they going to take up a new position and set up people who get the new system to the new satellite.

    Regards

    Hey Buddy,
    from your post i think i understand that it is the Optus-D3 bird. if it is then this bird has already been Launched & is Now Co-Located With Optus-C1 Bird @ 156.00E. YES This is an Optus Bird. Some Transponders are active and Transmitting Test Programs While the Other are NOT.

    Regards,
    Dishnit

    Just like Dishnit said

    you will find it will be parked right behind the old C1 so no need for moving the dish

    You're a little late with your news. D3 was launched over a month ago and after the current testing, is due to come on line about 15 th November.
    Read all about it here:-

    what happens to the C1 after they go live with the D3?
    do they bring it back to earth or just blast it down?
    or does it just continue braudcasting infrount.

    It continues operating, with some services transferring to D3 and other services being added to C1.

    Nah, nothing spectacular like that.
    It will be used to augment the existing services. That is why it is co-located.
    Effectively it more than doubles the number of possible channels that can be used without moving your dish.
    Rather doubtful if the quality of programming will improve, it will just enable more repeats and commercials.

    Optus Singtel will be surprised to read this...

    D3 is co located alongside C1 and will share some of the work making other transponders available.

    I wonder has it been determined when to start planning for either an additional Bird to join C1 & D3 or to eventualy replace C1 when its projected service life expires or am I late as usual with a very obvious question and pen has been put to paper to start the ball rolling ?

    After reading the heading for this thread, I also wonder how many more people will think that Fox/Austar thru the benevolence of Optus, are actually launching the "NEW" satelitte on Sunday Morning, the 15th of November for all the new channels and features??

    They wouldn’t want to promote Optus by giving them due credit. I am sure Foxtel think it is their satellite, Optus only own the satellite. I actually find it funny now, the advert does claim that it is Foxtel launching the satellite. I would like to know what Optus have to say about that.

    Optus couldn't care less what Foxtel advertise, they have been paid for the service and little else matters.

    I asked a similar question on another forum, regarding the '15 years life' bit and a very helpful member by the name of VK2XSO gave me this reply

    "It appears that geostationary satellites are a bit of a mystery even for a satellite forum.
    Having worked with them directly for over 10 years and as a hobbiest over 20 years, I've never seen one in person.

    The length of time a satellite remains in service is dependent on a number of factors.
    Primarily the fuel they carry is one of the most obvious. Their missions are typically 10 years. More fuel requires more money to get them into orbit and they use more fuel to manoeuvre.
    The reason why they require fuel as Leroy mentioned above is to keep them in the correct orbit. The gravitational and tidal influence of the sun and the moon pull the satellite out of its perfect orbit.
    If you have a large accurate dish, you will notice the position of the satellite in the sky changes. They wobble. On very large earth station dishes, the satellite's wobble is constantly happening and they need to track the satellite. It's not unusual for them to adjust their position once every couple of seconds.

    As time goes by, the satellite's wobble gets bigger. If left to it's own means the satellite will appear in an inclined orbit which becomes progressively worse.
    So about once every two weeks, the satellite controllers correct the satellite's drift and put it back in it's slot. In the case of an inclined orbit satellite, there is much less effort required and thus, less fuel used. The satellite doesn't require precise positioning, just a quick nudge to keep it in the general area of the sky.

    Now it might sound like they use a lot of fuel to move them into a new slot. This isn't Star Trek, satellites obey real world laws of physics. They do not use any fuel to move them from a slot over Europe to a position over the Pacific. They use one burst of fuel to get them moving and another burst to stop them moving.
    Lets say a satellite moves from the 0 deg slot to 180 slot. This is a 132000km trip.
    Give the satellite a quick nudge and move it at 100kph and it will take 55 days to make the trip. Using only two short bursts. The engines don't constantly fire.

    So moving the satellite really doesn't use all that much fuel.
    The life time of the satellite can be greatly increased by allowing it to wobble more than usual or allowing it to be in an inclined orbit. The life expectancy can be increased to 15 years quite easily, or even 20 years.
    It pays to remember that all the electronics are subject to large amounts of radiation over their lifetime, and very large temperature variations. The fatigue stress placed on all parts of the satellite slowly break it. Batteries wear out, solar panels become less efficient, tubes go soft and components just eventually fail.
    Another factor is technology. Why keep an old satellite like A1 in service when it can be replaced with a nice shiny new bird with a much better performance. In 30 years, compare the difference between A1 and D1 satellites, or Intelsat 301 and 801.
    Use up the satellite for all it's worth and replace it with something superior as soon as it comes along to make more cash.

    When it comes to the end of the satellite's life, that last amount of fuel is used to push it out into graveyard orbit. This is slightly further out. But because there is no atmospheric resistance their orbit will not decay for a very very long time.

    It's often been asked why we don't recover the satellites. They really are a long way out. The space shuttle's orbit is typically ~300km, geosync satellites are 36000km out.

    Imagine recovering the electronics from your house in 1990. VHS VCRs, people in Australia didn't even have VCD, there was no DVDs. The most common processor in home PC's back then was an 8086. IBM PC XT !! 80286 AT computers were expensive.
    The only use recovering this technology has now is something for kids to point and laugh at ! As far as museum pieces go. Those satellites will be reasonably well preserved in orbit for a couple of thousand years. They're tomorrow's fossils."

    Those satellites are tomorrow's lethal bullet. It should be a requirement for all sats after they reach end of life to deorbit and burn up in out atmosphere. As long as they remain in high earth orbit they will stay there essentially until they collide with something be it another very expensive satellite or far worse a human occupied vehicle.
    The term 'satellite graveyard' totally downplays the reckless action of leaving sats in that orbit. It could end up being a human graveyard well into the future in which humans regularly venture out to the moon and beyond.

    That’s easy to fix. Just mount large plasma cannons to the ship then you can blast a path through. LoL

    Although seriously at that point it probably will be financially viable to go up and retrieve them and recycle there materials.

    Actually one good use for 'Dead' satelittes would be as targets for the laughable 'Star Wars' defence system proposed by the late US Prez, Ronnie (Yippeee Ki-Yayyy) Reagan.

    I didnt realise the so called Geo stationary Sats moved about quite as much as they do.
    I knew that their orbit isnt circular due to the various magnetic forces but not the 'wobbles'.
    Not such a problem for those big dish's with the ability to adjust but not so good for the DTH small dish's we use now.

    The last thing you would want to do is shoot at the dead satellites. It turns one object that could kill you into thousands or millions of objects that could kill you and makes a larger portion of space hazardous. When the chinese blew up one of their satellites with a missile they created thousands of debris objects that could potentially kill astronauts or damage other spacecraft.

    Why is it not so good? The beam width on small dishes is huge by comparison to the large dishes with very narrow beams that have no choice but to have tracking hardware. A low gain dish would be far less susceptible to satellite movements than a larger one.
