AMOS 5 IS GONE FOR GOOD

First topic message reminder :

Israel’s Amos-5 satellite went dark on November 21st with its owner Spacecomconfirming last week that it could not communicate with the spacecraft. Spacecom said that it had attempted to re-connect with the satellite, at its 17 degrees East orbital location. Ground observation, via powerful telescopes, confirmed that the satellite was still at itsnominal position. The satellite was launched in December 2011, so was barely one-third into its operating life of some 15 years.All satellites come – sooner or later – to an end-of-life. The normal situation is that the dying satellite maintains some on-board fuel so that ground engineers can use these final fuel supplies to boost it out of its normal geostationary orbit of 35,786 kms (22,236 miles) above the Equator. This final firing of the satellite’s thrusters is designed to lift the craft at least another 300 kms higher, and thus well out of the way of its orbiting neighbours.Indeed, since 2002 it has been a formal requirement that geostationary satellites are lifted into a so-called ‘graveyard’ orbit.But these rules cannot now be applied to Amos-5 which is slowly drifting as an uncontrollable “zombie” satellite. The problem is further compounded by the fact that the satellite will come extremely close to a number of near neighbours as its drifts away from 17 degrees East.A similar situation occurred back in April 2010 when an Intelsat-owned craft (Galaxy-15) went wrong and would not listen to controls from its ground technicians. However, the Galaxy-15 wasa true ‘zombie’ in that it continued transmitting. As it drifted from its official home of 133 degrees West it collected signals uplinked from the Earth and powerfully beamed them back to the ground.As the drift continued it moved perilously close to a number of other satellites, including SES-owned AMC-11, each of which were deliberately moved out of the way. At one point it was said that the Zombie had come within 5 kms of AMC-11, which is significantly too close.However, this particular story had a happy ending. By December 2010 the Galaxy-11’s on-board batteries had exhausted themselves and so the satellite – as they engineers had hoped –went into a safety mode, and had switched itself off, and in simple terms had re-booted its systems.The technology worked, and the satellite again started ‘listening’ to its ground bosses. It was the perfect Christmas present, not just for Intelsat’s talented team but for the other worried and hard working engineers who could now start sleeping at night. Following in-orbit testing by October 2012 the errant satellite was back working at its proper home, of 133 degrees West.Unfortunately, this solution is not likely for Amos-5. If, as it seems, the satellite iscompletely dead it will just continue to drift. And as it drifts through the Clarke Belt (named after Arthur C Clarke) the satellites in its path will just have to get out of its way – and use up precious fuel in the process.

pls direct me properly

Put it anywhere although its 3° west

the sat is called ABS 3A and the best tp is already mentioned above. 11150H45000

now you can combine amos 5 ,astra 4.8 ,eutelsat 7east and the continental package

I want to move my dish from 22'w to track this abs 3a.if I face the dish, where should I turn it to, left or right?

Right

just above 5east thats where Abs is.so the trick is nab SES5 then skew another lnb on top of it.with a difference of 3-4cm

let's make it more practical

good info

Have you managed to track it?

Yes very easy

pls will the dish face canal+ side? Pls shed more light.. This blackout don tire me.

Blackout as ow

They are there just rescan the TP

Pls help me on how to track this one, am confused..Is ses 5 same as amos 5? Ejo now

no completely different. Amos 5 was on 17degrees, Ses5 is on 5degrees

11150 H 45000 @ 5°West

Nice bird

I finally nail this bird...Hope more will join soon

pls i want 2 know how u nail it,is it west or east,above DSTV or below it.pls i want 2 know.

Just opposite dstv and a bit up (5°west)

Pls is mbc still on air

yea

Back of dstv

Obenar please tell me how to Cobne Amos 5 sees5 and abs on 1 dish tenks

@ u operajay wen u tracked ur 10928 H 30000 then push it right abit and put 11920 27500 H

Correct!!

amos 5 us dead my brother

the best option is for u to combine abs3 with ses 5 and 7east.for guys like u in the west u can nab it together with nilesat on 90cm

wow!

A m
anufacturer's assessment on Amos-5 said the most likely reason for its failure was, according toIsraeli media, a"complete breakdown in the electricity supply system resulting from an internal malfunction, external damage to a component in the electricity supply system, or related wiring".Amos-5 was in geostationary orbit over Africa, where it had provided communications services to the burgeoning market there. Its sudden loss forced Spacecom to shift transmissions toother satellites it maintains.Brett Biddington, of Canberra-based Biddington Research, said such losses"are not without precedent"."The satellite is in geostationary orbit so acollision is probably the least likely cause,"he said."You can rest assured that the agencies ofvarious governments will be looking closely at the situation to see what they can glean," said Mr Biddington, a space consultant and former RAAF officer.Amos-5 is in good company. There are a number of space craft orbiting in a state of permanent or semi-permanent rest.AMSAT-OSCAR 7 was launched in 1974. It went silent in 1981 because of a short circuit related to its batteries. Then it sprung back to life by 2002, when the circuit opened again – but now it works only when it receives direct sunlight in orbit.US-based satellite operator Intelsat lost control of Galaxy 15 in April 2010, when it began to drift from its course.Nine months later, after its batteries were totally depleted, it rebooted, using solar power, and jolted back to life and is now back in service, again.Others, like Amos-5, simply drift on, uncontrolled from the ground.So, even as Spacecom prepares its insurance claim on its failed satellite, thereis a shred of a hope that whatever caused the failure could one day reverse itself. However, those odds are truly astronomical.

it was beginning to be one of the best Sat but now gone for good

9jasat gone same way

why still talking about AMOS 5.

exactly bro.but still viva fta

Na wa oooo, so notin forever. especially free tin

pls I need d current tp for tracking multiTv. make port jare

Na d same frequency 12525v 27000

OK Tnx bro. Jst wanna be sure b4 I climb ladder

pls my fellow brodas is AIT in Ses 5 Still Working? Bcos On My Own End Is Not Working,i Want 2 Know Wat Is Happening.

Maybe its gone

completely and totally gone.

Gone 360

sme New channel jux popped up wen u blind scan Amos mega channels s free do u check it out but the signal isn't dat gud dou
