SpaceX Falcon 9 : Telkom 4 : ~late July 2018

Discussion Thread for launch of Telkom 4

NSF Threads for Telkom 4 : Discussion

NSF Articles for Telkom 4 :

late July or August on Falcon 9 to GTO.


I guess I should start a mission thread for this one soon (although it's still 20+ spots down the manifest):

Tweet from SSL:
Thumbs up! TELKOM-4 is progressing through SSL’s Palo Alto factory on schedule.



Telkom 4 has a C-Band payload with 60 transponders, 36 for the Southeast Asia market and 24 for the Indian market.  It is using the SSL 1300 bus and will be positioned at 108 degrees.  Telkom 4 is a replacement for Telkom 1, which failed on August 25, 2017 before its planned retirement in 2022.

SSL SELECTED AS WINNER OF PROCUREMENT FOR COMMUNICATIONS SATELLITE TO TELKOM, INDONESIA’S LARGEST TELECOMMUNICATIONS AND NETWORK PROVIDER

PALO ALTO, Calif. – December 30, 2015 — Space Systems Loral (SSL), a leading provider of commercial satellites, today announced that it was selected to provide a communications satellite to PT Telkom Indonesia (Persero) Tbk, the largest telecommunication and network provider in Indonesia. SSL was informed last week that it is the winner of the procurement of the TELKOM-4 satellite, which will be used for fixed satellite services in Indonesia, India, and Southeast Asia.

“Satellite services are particularly important in regions such as Indonesia where the population is spread over thousands of islands,” said John Celli, president of SSL. “For SSL, this is the third satellite for Indonesia that we will add to our backlog and we are honored to play such an important role in expanding the telecommunications infrastructure for the nation and the region.”

"Because our country consists of thousands of islands, Indonesia needs satellite technology,” said Alex J Sinaga, president director and chief operating officer of Telkom. “Satellite complements our other technologies, such as submarine cable, as the backbone that connects the islands of Indonesia.”

The satellite will be based on the highly reliable SSL 1300 platform, which provides the flexibility to support a broad range of applications and technology advances. It is designed to provide service for 15 years or more.

[detikInet Feb 16, 2017] SpaceX Launches Still Trust Telkom 4

Telkom still high reliance on Elon Musk's SpaceX owned satellite launch Telkom 4, despite a little incident on a satellite explosion Facebook.
...
As planned, Telkom 4 later when it was launched with estimates in June 2018, will occupy the orbital slot 108 degrees longitude (BT). This satellite will replace one whose term Telkom remained active until 2022.

[detikInet Sep 11, 2017] Buyarnya Telkom 4 Satellite Plan on August 17, 2018

Telkom 4 satellite is planned to be launched on special day. Precisely on August 17, 2018. However, due to Telkom 1 satellite anomaly, the launch schedule may change.
...
"Specifically for Telkom 4, we have coordinated with the satellite manufacturer to be able to advance 60 days, but the manufacturing itself, the launch itself, we coordinate with the launcher, whether the queue can be advanced, if it can succeed, then Telkom 4 can go early," continued Alex .

20 down isn't as (conceptually) far away as it was in 2013. or even 2016...

An article mentions them trying to move the launch up to May.  Given the state of the SpaceX manifest that seems unlikely unless they're jumping in front of some other payloads, but maybe it will happen.

Hard to tell context from Google Translate, but maybe they are trying to get on a used booster to launch sooner...

It is possible thanks to the Falcon 9 rocket that can fly repeatedly.

They've had statements like that in many stories when talking about SpaceX, it doesn't necessarily mean anything for this flight.  (They could very well be reusing a booster to accelerate the schedule, I just wouldn't assume it from that line in the article.)

Hmmm...

If the sat shows up at the cape by mid March then a launch in May is highly likely.

Think of SpaceX launch processing and launch at the Cape/KSC as a FIFO buffer. Launch dates are assigned once the sat reaches the local area for the beginning of launch processing. If it reaches the area before others that had prospective dates before it, it would launch before them. In the words of the AF 45th SW commander that SpaceX is all about go when ready. If Telkom 4 is the next sat ready then it would be the next sat launched.

No.  That is not true.  Until SpaceX catches up on their manifest (which will be another year) it can't become true.

[Antara News] Telkom 4 Satellite is launched May-August 2018
Quote
Telkom 4 satellite will be launched mid-May to August 2018 with SpaceX's Falcon 9 rocket SpaceX space company from the United States.

Director of Network and IT Solution of PT Telkom Indonesia Tbk Zulhefi Abidin said in Jakarta on Thursday (18/1), Telkom 4 Satellite is targeted to be assembled and tested in March 2018.

"The launch has slots, schedule, schedule between May and August 2018, that's our slot, "he said.

This is the Google Translate version, so I wouldn't read too much into any particular word  ;)

If a satellite isn't ready, it can't be launched... so there is SOME truth to this, any satellites that are ready to be launched would presumably go ahead of satellites that aren't even at the cape yet....

But wouldn't they purposefully not ship to the cape too far in advance?

Have we heard anything else from Telkom on if they've agreed to launch on a reused booster?

Yes and they announced that way back in May 2017.

That sounds to me like they are talking about the economics of Falcon 9 being reusable, not that they have agreed to fly on a reused core.  I don't think that this means that they won't, but this statement does not indicate to me that they will necessarily be on a flight proven booster.

Text seems to me like they are planning to use the reflown booster and discussing the savings realized.  May just be a translation/parsing issue of the word 'as.'  'If' would have been they are still deciding; 'since' would have been definitive in American English.  I think the message was the latter.

A bunch of Indonesian articles today give the launch window as mid-July to August, which fits nicely with the late-July target reported by Ben Cooper.
