Title: Ofeq 11 - Shavit-2 - September 13, 2016
Post by: chewi on 09/13/2016 04:23 PM
Israel’s most advanced reconnaissance satellite Ofeq 11 launched into space
http://www.jerusalemonline.com/news/politics-and-military/military/israels-ofeq-11-satellite-launched-into-space-23599

The Israeli Defense Ministry and Israel Aerospace Industries (IAI) launched the Ofeq 11 satellite – the most advanced reconnaissance satellite developed by the IAI - from Palmachim Air Base this evening (Tuesday). The Ofeq 11, whose objective is to collect critical intelligence, is Israel’s fifth reconnaissance satellite in space.

The Israeli security industries, the Defense Ministry and the IAI are all waiting in suspense to see that the launching was successful and that the satellite is fully functioning following the explosion that occurred two weeks ago during the launch of Israel’s Amos-6 communications satellite in the U.S.

I assume that this is a new optical reconnaissance satellite rather than a radar TecSAR payload.   The first use of the new OpSAR-3000 platform for the optical series?

And yesterday I finalised the proofs for my latest paper detailing the Israeli reconnaissance satellite programme for the Space Chronicle series of the Journal of the British Interplanetary Society!   To late to update now.

Don't expect TLEs from Space-Track - Ofeq TLEs have been classified since 2011.

No NOTAMs for the launch? Have the Israelis released them in the past?

no because the rocket launches out of a permanent GND-UNL Civilian no fly zone so no need to update the public.

Based on my amateur analysis of Ofeq TLEs and the passes over Israel this morning on Heaven's Above, a replacement for Ofeq 9 seems likely and logical due to its age.    I think I have the UTC offset correct but maybe not...

Would you mind posting an update here when it is published? I look forward to reading your article.

According to the Haaretz, there may be some technical problems with the new satellite: http://www.haaretz.com/israel-news/1.741864

After the satellite was sent into orbit and as it flew over Israel, readings were received that may indicate problems, officials said.

Ofer Doron, aerospace chief for the Israel Aircraft Industries, said "there are a few matters that don't seem routine, but the process of diagnosing the satellite's situation is continuing."  

The Ofek 11 was launched from the Palmahim air base, south of Tel Aviv, at 5:30 P.M. as surveillance aircraft patrolled the nearby Mediterrean skies.

From Arutz Sheva 7, (http://www.israelnationalnews.com/News/News.aspx/217741)...

Amnon Harari, head of the space department in the Defense Ministry, said: "We made contact with the satellite, we know it entered its orbit going around the earth every hour and a half.

"We are in continued contact with the satellite and are monitoring its condition. There are indications of some things that aren't working as we expected. We're trying to stabilize it, and this will take a few days," Harari explained.

If there are problems with the satellite, I wonder if these could be because of the new OpSAT-3000 platform that is being used?   There have not been similar reports of problems with other Israeli satellites that have reached orbit.

Ofeq reconnaissance satellites have always performed a perigee-raising manoeuvre at their first pass through apogee.   Therefore it will be interesting whether Ofeq 11 has successfully performed this manoeuvre, since problems have appeared so soon after orbital injection.

From the Jerusalem online (http://www.jerusalemonline.com/news/politics-and-military/military/israeli-defense-ministry-ofeq-11-satellite-not-working-as-expected-23606)

Mere hours following the Ofeq 11 satellite launch from the Palmachim Air Force Base, Israeli Defense Ministry officials suspect that several of the satellite’s crucial systems are not properly functioning. “The satellite’s first hours are always difficult,” a senior level official said. “There are indications that things are not working as we expected.”

OK, so that leads back to news.ru.co.il which appears to be a real source. Odd that only Russian-language Israeli media seem to have given the time.

I've used 14:38 UTC from the NSF thread as liftoff, but I did note that
http://www.haaretz.com/israel-news/1.741864

quoted 5:30pm as launch time [presume local time].
At the time, I assumed that it was just an approximation or rounding.

Thanks

For those interested in trying to see the satellite, Ted Molczan has amended his search elements.  http://www.satobs.org/seesat/Sep-2016/0088.html

"Ofeq 11 has been assigned the international designation 2016-056A, and the USSTRATCOM catalogue number 41759"

The Israeli Defense Ministry gave its official confirmation that the Ofek-11 reconnaissance satellite that was launched last week has in fact been stabilized and transmitted first images from space

Yesterday, the claims that Ofek-11 transmitted first pictures from space were initially denied but now they have been officially confirmed, as has the fact that continuous contact with the satellite has been achieved

Slightly more clarification since yesterday.

A team of engineers and operators from Israel Aerospace Industries (IAI) and the Space Administration at the Ministry of Defense's Directorate of Defense Research and Development (DDR&D), operated this evening (September 22) at 17:10, for the first time, the payload of the observation satellite Ofek 11, and successfully downloaded the first pictures from the satellite.
