Space Communications lost contact with the Amos 5 satellite

The connection was lost this morning (Saturday) at 06:45. About two years ago, Haval Communications reported to the stock exchange that one of the engines was dead and therefore estimated at the time that the life of the satellite would be shortened * Unlike the other Amos satellites built by the Aerospace Industry, Amos 5 was built by the Russian ISS company

Halal Communications announced this morning (Saturday) that it had lost contact with the Amos 5" satellite and as a result the services provided by it to customers, mainly customers in African countries, ceased. According to the company's announcement to the stock exchange, contact with the Russian-made satellite was lost at 6:45 a.m. Saturday. According to the company, this is an unusual event and it is difficult to even recall an event in which contact with a communication satellite was cut off in this way.

At this stage, the company has no information about the nature of the fault that caused the loss of connection. So far the company has not been able to renew the connection with the satellite.

The satellite is covered by insurance for 158 million dollars. Halal is traded on the Tel Aviv Stock Exchange at a value of approximately NIS 1.1 billion. According to the company's financial reports for the second quarter of the year, the backlog of Helvin's orders as of July was 136 million dollars. The satellite is listed in Halal's accounting books at a value of 136 million dollars.
The Amos 5 satellite mainly served customers in Africa. In February, the Amos 6 satellite is supposed to be launched, this time again produced by the Aerospace Industry, which also produced the first four Amos satellites. As you may recall, this satellite caused an uproar when Facebook announced that it had purchased all of its internet capacity for the first five years with an option to extend it by two years for $100 million, for the benefit of developing countries, mainly in Africa.

The experience so far shows that the construction of a satellite of the type of Amos takes 3-4 years.

shortening the life of the satellite

However, the writing was apparently on the wall. About two years ago, in October 2013, Haval Communications issued a notice to the stock exchange in which it immediately reported a malfunction in the Amos 5 satellite. The company updates that a malfunction was discovered in the Amos 5 satellite that impairs the power supplier's ability to command the activation of two additional engines."

"Based on the opinion of the satellite's manufacturer, the Russian ISS company, the malfunction may shorten the life of the satellite by about 11 months. If it is not possible to run additional engines using power supply No. 2, a more significant shortening of life may result. There are alternative operating routes for operating the engines which are being tested by the satellite manufacturer."

  1. Father, could you check and report if more is known today about the circumstances of the disconnection
    Was it known when the article was published?
    About 10 days have passed since the connection with the satellite was lost
    The issue dropped from the media

  2. The satellite itself must be separated from the communication channel.
    Was the communication channel also developed in Russia?
    It is possible that the satellite continues to function properly and the fault is related to the communication channel.
    Is there only one channel?
    In the Gulf War, a Patriot missile missed a missile hit because one of the variables overrode the 32 bits assigned to it in the software.
    Wasn't surprised if it turned out even now that some critical time-related counter had been messed up.
    The software security company usually checks what the developer instructs them to do so that errors like doubt will be discovered before.
    And all this if indeed the disconnection is due to a software glitch.

  3. Lorem,

    I guess it's a matter of economic consideration, if there was a budget they would probably also produce 10 copies of each satellite.

  4. The matter of suddenly cutting off contact is very strange. Does the company not have a telemetry channel that tells it about the satellite beams and faults in the system before the connection is definitively cut off? Have they ruled out damage to the satellite by space debris, or even by a hostile satellite or a group of hackers that took control of it?

    Already a month and a half ago, upon buying the entire capacity of Amos 6, I mentioned that it might be worth ordering another copy of Amos 6, and not waiting for the development of Amos 7. So maybe the time has really come.
