Kacific selects SpaceX to provide launch service

Kacific Broadband Satellites Group (Kacific) has selected SpaceX as the launch provider for its Kacific-1 satellite, which is being built by The Boeing Company.

Kacific-1 will be launched on a SpaceX Falcon 9, a two-stage orbit-class rocket designed from the ground-up for maximum reliability and reusability.

“SpaceX has a breadth of vision that appeals to us,” says Christian Patouraux, Kacific CEO. “The company is committed to changing the way people think about space and the possibilities it represents. Signing with SpaceX as our launch service provider is a major step towards delivering our own vision. We look forward to seeing Kacific-1 atop a Falcon 9 Rocket in 2019.”

“SpaceX is proud to partner with Kacific on the milestone launch of the company’s first satellite, Kacific-1.” said Gwynne Shotwell, President and COO of SpaceX. “We appreciate their confidence in our proven capabilities and look forward to delivering their satellite to orbit.”

In February 2017 Kacific placed an order with The Boeing Company for the Kacific-1 satellite. Based on the reliable 702 satellite platform, Kacific-1 is designed to deliver high speed broadband via 56 narrow Ka-band beams, with the most powerful signal level ever achieved in a commercial satellite in the South East Asia and Pacific regions.

[Space News] Kacific to double in size as first satellite launch nears, mulls second satellite
Quote
Patouraux said Kacific-1, a high-throughput Ka-band “condosat” that shares the same chassis as Japanese operator Sky Perfect JSAT’s JCSAT-18, is slated for launch in the third quarter of 2019. Boeing is building the satellite.
...
Originally announced with 57 beams, Patouraux said Kacific and Boeing finalized the design of Kacific-1 with 56 beams after a final tweak to the satellite’s coverage in 2017. All but two beams have pre-launch customers, he said.

KACIFIC1 HIGH THROUGHPUT SATELLITE

Kacific1 is a next-generation geostationary satellite operating in the Ka-band frequency spectrum. The satellite will launch in late 2019 and stream low-cost, high-speed, reliable, and stable satellite broadband via 56 powerful spot beams. Wide reaching coverage will extend over 25 countries in Asia Pacific with populations spread across their many islands, mountainous and rural regions. Utilising advanced ground segment technologies, Kacific1 will deliver fast internet speeds with a robust quality of service on a small user terminals at a jaw dropping price per month.

MANUFACTURED BY BOEING. LAUNCHED BY SPACEX

Designed and built by Boeing, the Kacific1 payload is supported by the reliable 702 MP platform. Kacific1 will launch atop a two-stage SpaceX Falcon9 rocket, which will ultimately bring Kacific1 into geostationary orbit.

Kacific and SKY Perfect JSAT share the cost of the satellite platform in a condominium arrangement. This platform supports the Kacific1 payload and a payload of SKY Perfect JSAT, which allows both parties to realise efficiencies in manufacturing and launch costs.

Kacific1’s coverage was designed with additional capacity expansion in mind. By launching other follow-on satellites into different orbital positions, Kacific will be able to provide additional capacity in the Kacific1 coverage areas requiring more, as well as increase the total coverage area.

HIGH THROUGHPUT

Kacific1 is a High Throughput Satellite (HTS) because it reuses the same spectrum (frequencies) multiple times in the 56 spot beams. This stands in contrast to traditional FSS satellites with wide area beams that can use the spectrum only once. In a sense, an HTS is similar to a mobile cellular system that reuses frequencies between cells. Consequently, the total HTS throughput is much higher than an FSS satellite resulting in greater spectral efficiency and therefore lower cost per bandwidth. Modern technologies such as adaptive coding and modulation (ACM), signal pre-distortion and uplink power control are used to increase the throughput and overall availability, and, ultimately, improve the quality of service and user experience.

TECHNICAL SPECIFICATIONS

    56 high throughput spot beams
    Delivering up to 60 Gbps of broadband capacity
    550 to 600 ms latency
    Ka-band system
    Geostationary orbit
    6,800 kg at launch
    13 kw of electric power

Since JCSat 18/Kacific 1 is 6.8 tons, is it likely that the Falcon 9 will take it to a sub-synchronous transfer orbit since the first stage might make a droneship landing?

F9 can do 5.5 tonnes recoverable.  Increasing the mass to 6.8t reduces the lift by about 350 m/s.  This is just about what they could gain by foregoing recovery.  So the two most likely options are:
(a) Recover the booster, and accept a sub-GTO apogee (about 21000 km by my estimate, or 2150 m/s deficit), or
(b) Expend the booster, and get a GEO-apogee GTO (about 1800 m/s deficit).

I suspect, without evidence, that (a) is more likely since they've already done this with several block 5s.

The JCSAT-18 part of this satellite is an Ku-Band payload. Unfortunately, there is very little information on JSAT.

My guess is that the September launch is actually Starlink-2 rather than JCSAT, but it's just a feeling.

Kacific1 Milestones: Bus and Payload Integration Complete
Jul 04 2019

If you were to step inside the Boeing Satellite Systems International (Boeing) Factory in California, you would see that Kacific1 has doubled in size from a month ago. The payload and bus modules are now successfully tested and integrated, and the spacecraft is proceeding along in single-line flow.

Solar arrays, which will convert the sun’s rays into electricity to provide power to the satellite, and its antenna reflectors which focus the electromagnetic waves into the high-power spot beams, are being installed

The XIPS (Xenon Ion Propulsion System) electric thrusters are also being fitted.  Electric propulsion systems are lighter than chemical propulsion systems, and so allowed Kacific to place more communications hardware on board.

Boeing will soon begin vibration and acoustic tests to simulate the harsh launch environment. These tests will be followed by spacecraft thermal vacuum tests (SCTV). SCTV tests simulate the space environment to ensure that the spacecraft will remain healthy for its 15-year design life. Other activities underway include launch, mission and in-orbit test planning.

For Kacific1 to provide connectivity to many small VSAT terminals across Asia Pacific, it needs to connect to a powerful RF ground system. Kratos Defence and Security Solutions is designing, building and commissioning our multi-site gateways, which includes large 9-metre antennas and the high power amplifier equipment needed to transmit to space. Currently the RF gateway hardware is being shipped to the sites for installation.

At each RF gateway is a Kacific hub where connections to the internet are established. These hubs are based on the Newtec Dialog® multiservice platform and are currently being built in Belgium. They will soon undergo a factory acceptance test (FAT). Each of the hubs will be controlled at the Kacific network operations center (NOC) in Singapore, which is also being developed.

We’re keeping in regular contact with our technology partners to provide exciting updates and successful test results. All systems are firing here at Kacific as we begin the countdown to Kacific1 service commencing.

FY2019 in Japan started on April 1, 2019. So second half starts on October 1st.

Anyway, it doesn't matter, SFN schedule shows that this launch is now NET November.

Simultaneously, Shotwell stated this morning that "this is [the] first year we’re ready before customers [which is] why some launches [are] slipping into 2020." So it's probably a satellite/customer-side delay.

I found two recent articles saying November for Kacific, they were issuing press releases saying they were still launching this year despite the tweet from PBdeS, SFN had them as NET November and now shows the November launch as JCSAT-18.  Ben Cooper is also showing JCSAT-18 as one of the next few launches.  If you find any recent information putting one of those other payloads in November please post it.

Possible pad switch to 39A.

Looks like JCSAT-18 may be moving to Pad 39A. At the very least, they now have the option to launch the mission from either pad.

I thought JCSat 18/Kacific 1 was launching from 39A as stated by Michael Baylor.

The FCC application just gave the option to launch from 39A. Evidently, they have chosen to stick with 40.
It’s a beautiful day to go to space.

Kacific1 satellite arrives at SpaceX launch site in Cape Canaveral, Florida
Nov 15 2019

Cape Canaveral, FL. 14 November 2019 – The Kacific1 communications satellite, built by Boeing, has arrived at SpaceX facilities in Cape Canaveral, Florida, where it will be launched atop a Falcon 9 rocket to geostationary orbit.

Owned by Kacific Broadband Satellites Group (Kacific), this next-generation high-throughput Ka-band satellite will stream broadband to 25 nations in South East Asia and the Pacific Islands via 56 spot beams. Kacific1 is based on Boeing’s reliable 702MP-satellite platform and will provide the most powerful signal level ever achieved in a commercial satellite in the region.

Christian Patouraux, Kacific CEO, founded the company in 2013 with the vision to provide high speed, affordable and accessible internet to extra-urban, rural and remote users. He saw a critical, unmet need in the Asia Pacific region, where high prices and unsuitable technology were prohibiting access. By combining next-generation satellite technology with a lean business model that cuts out the middleman, Patouraux has developed valuable infrastructure for local organisations and people.

Kacific1 will deliver high-speed broadband services to previously unserved or under-served people in nations where populations are widely dispersed, and therefore expensive to connect. Many of these nations are archipelagos or have rugged mountain ranges and large rural territories, making satellite technology the best – and sometimes only – way to connect to the internet and phone networks. The Kacific system will be particularly appealing to the needs of health and education departments in provinces and villages. Furthermore, satellite broadband access provides critical communications channels to a region which is often victim to tropical storms, cyclones, earthquakes and tsunamis.

The Kacific1 payload will share a satellite bus platform with JCSAT-18, ordered by SKY Perfect JSAT Corporation.

Kacific has been recognised globally for its work towards better social outcomes through communications technology. Kacific won the Best Digital Inclusion Award 2019 at ICT Days, Vanuatu, and received a Better World Satellite Award in 2018 from the Satellite and Space Professionals International.

Now this is the next launch, in 9 days, from KSC/CC, from LC-39A.

When will SpaceX suspend Starship pad work in favor of this launch campaign?  It would have to be suspended for the static fire as well?

Are there any outstanding issues regarding 39A, or is it ready to go?

It's going from LC-40, not 39A

Is there much of a change to the TE for LC-40 ...when going from cargo launch to a launch involving a fairing?

I may have answered my own question...

wrt TE config...CRS to fairing

CRS-17, May 4, 2019
Starlink V0.9, 16 May, 2019 scrub, upper level winds23
Starlink V0.9, 23 May, 2019 launch

The LC-40 pad crew demonstrated a 12 day reconfig...CRS to fairing.

Here, we have CRS-19 launched on 5th of December with JCSAT-18 NET of December 15/16, 2019.
This would appear reasonable, even without a slip to the right.

Just a WAG, but it appears that the customer TE config changes are umbilicals with TE/pad box hookups and AC hoses. The major time constraints would be for post launch TE/pad repairs, consumables replentishment, pad testing, software, permits and launcher logistics/assembly and testing. The TE config either way is very minor in the grand playbook of events at LC-40.
 
 note...I do not know the proper name for the TE upper sling arms or its actual purpose. I had assumed that it was a recoil mechanism for the fairing hoses and doubled as a fairing support strap when the TE is horizontal. The yellow "strap" has been removed for most CRS missions at LC-40. Pad KSC 39A has a similar sling arm for "fairing" launch but has it removed for CRS and Commercial Crew.
--------------------------------
LC-40

Vertical...prelaunch/launch  "fairing"
-Customer electrical ground support equipment (EGSE) thru S2 catenary umbilical (via pad box).
-Payload environmental control attachment/pad selectable AC to fairing hoses.
-Fairing structural support ? (sling arm open with strap, stage 2 strongback "arms" closed, TE interstage support static)

Vertical...prelaunch/launch  "CRS"
-Customer EGSE via Dragon umbilicals.
-Capsule environmental control via Dragon umbilicals.
-Capsule structural support ?  (sling arm open with strap removed, stage 2 strongback "arms" closed, TE interstage support static)
---------------------------------
LC-40

Horizontal processing/hanger/rollout   "fairing"
-Customer EGSE via processing/hanger box to payload adapter interface/catenary umbilical.
-Payload environmental control attachment via processing/hanger HVAC/pad selectable AC to fairing hoses.
-Fairing structural support ?  (sling arm closed with strap, stage 2 strongback "arms" open, TE interstage support under load)

Horizontal processing/hanger/rollout   "CRS"
-Customer EGSE via processing/hanger box to payload adapter interface/catenary/Dragon umbilicals during progression.
-Capsule environmental control via processing/hanger hookups and Dragon umbilicals
-Capsule structural support ?  (sling arm open with strap removed, stage 2 strongback "arms" open, TE interstage support under load)
----------------------------------
 
I may have messed up a few details and used improper naming conventions. After all this, I am sure that a customer TE reconfig either way is a minor event at LC-40 and if we remove FH from the discussion, the same holds true for 39A.

[Space News] Kacific, with SpaceX launch imminent, borrows $160 million for satellite refinancing
Quote
Kacific said it recently secured $160 million from the Philippines-based Asian Development Bank and GuarantCo, a European- and Australian-government backed infrastructure investment organization, along with other financiers.

The $160 million enables Kacific to repay the short-term loans it obtained while Ex-Im Bank’s lending window was effectively closed to satellite deals, the company said.

If the launch is not delayed (and I didn't miss something), it should be the shortest turnaround at a single pad for SpaceX.

11 days, 6 hours, 40 minutes, 36 seconds if they launch when the window opens.

12 days, 1 hour, 21 minutes, 4 seconds is the current record as far as I know (CRS-18 -> AMOS-17).

Not that it really matters, but I beleive your post was wrt launch to launch pad turnarounds.  One should consider launch to scrub (non pad related) as well...

an example...
CRS-17, May 4th, 2019 launch at 2:48 am EST
Starlink V0.9 May 15th, 2019 scrub at 10:30pm EST due to upper level winds...pad was ready.
This one was 11 days, 19 3/4 hrs...
May be an idea to refilter data with new qualifiers...

Is it normal for a satellite’s mass number to change as launch day approaches?

JCSat 18/Kacific 1 went from 6,800 kg to 6,956 kg a couple days ago.

A fit to previous missions would suggest about a 2151 m/s deficit to GTO for a mass of 6956 kg.

Previous high mass missions with recovery have used about a 27 degree transfer orbit.  This takes about 1802 m/s to circularize and remove inclination with an apogee burn.  So if the total deficit is 2151 m/s, then the satellite should use 349 m/s to increase apogee, then circularize.

At 27 degrees, starting from a 230 km circular orbit, it takes 2448 m/s to reach a GEO apogee.  If the satellite is 349 m/s short, as we estimate, then it will achieve a dV of 2097 at cutoff, resulting in a apogee of 21,100 km.

So overall, I predict a resulting orbit of 230 km x 21,100 km x 27o.

Note that up through the last recovered GTO launch, Nusantara Satu, SpaceX has been slightly tweaking upward the speed at stage separation, as they experiment with how little fuel they can reserve for landing.  If this trend continues, performance might be slightly better than predicted from the Nusantara Satu mission.

SpaceX seems to have not pushed the first stage very hard.  Cutoff was at 8207 km/hr = 2280 m/s.   For comparison, the last GTO launch with recovery (Nusantara Satu) staged at 8517 km/hr = 2366 m/s.    The extra mass of the payload can only account for about 10 m/s of this.  So SpaceX seems to be being more conservative.

Subtracting 80 m/s from the separation should have the same effect on final V.  So I'm revising my apogee to 19,000 km (down from 21,000 km).  Final dV remaining to GEO should increase by the same amount.

Fairing recovery won't happen until around 45 minutes after launch; by that point, payload deployment would have already occurred.

Congratulations to SpaceX, SKY Perfect JSAT and Kacific for the successful launch and landing!

GTO cutoff was 33,700 km/h at 281 km. Assuming a 27 degree initial inclination, I get an apogee of 20463.1 km and a delta-V to GEO of 2169.5 m/s.

http://www.sworld.com.au/steven/space/speed.zip

Enter initial perigee height (km): 281
Enter SpaceX speed (km/h): 33700
Enter initial orbit inclination (deg): 27

Estimated inertial speed = 9793.8 m/s
Estimated apogee height = 20463.1 km

Enter required inclination change (deg): 27
Enter final orbit height (km): -1
Geosynchronous altitude = 35786.0 km

Burn at   281.0 km: theta1 =  0.27 deg, dv1 =  377.1 m/s
Burn at 35786.0 km: theta2 = 26.73 deg, dv2 = 1792.4 m/s
dv = 2169.5 m/s

Looks like SpaceX was just being more conservative here.

Compared to Nusantara Satu, the first stage cut off at 80 m/s less, with a correspondingly lower altitude.

The fuel saved allowed them to do a longer re-entry burn (23 sec vs 17), and a longer landing burn (27 sec as opposed to 20 sec - likely a single engine burn, as opposed to 1-3-1.)

My guess (and it's only a guess) is that the contract called for a 20,000 km apogee, and SpaceX figured they could meet that number with a trajectory that's a little easier on the booster and a little less risky.

Replace the Intellians with Seatels, which can handle far more vibration and movement without losing lock. I had the same trouble with the same model Intellian they use. Sneeze on them and they lose lock. The Seatels would shake so hard on our tubs they'd looked like a blur and still work.

Those who danced were thought to be quite insane by those who couldn't hear the music.

Can anyone tell me when OCISLY is returning to Port? I came down from Charlotte to see the launch and hoping to see the core returning before I return. Thanks

Here's the latest OCISLY post from SpaceXFleet Updates's Twitter feed.  Unfortunately it doesn't give an ETA.

B1056 has been secured and Of Course I Still Love You is underway towards Port Canaveral!

650 km (from the Updates thread) at 6.6 knots = 12.2 km/hr is ~53 hrs.

That puts arrival near sunset on Thursday, if they can keep up the pace.

What kind of wastrels would dump a perfectly good booster in the ocean after just one use?

Congratulations to SpaceX, SKY Perfect JSAT and Kacific for the successful launch and landing!

GTO cutoff was 33,700 km/h at 281 km. Assuming a 27 degree initial inclination, I get an apogee of 20463.1 km and a delta-V to GEO of 2169.5 m/s.

New cataloged object with initial orbital parameters:

2019-091A - 2019-12-17 05:00 UTC - 272.73/20319.41km/26.87°

My prediction of apogee was only 0.7% higher than actual!

Wasn't able to stay long enough at Port Canaveral to see OCISLY come in, but on my way home this morning I noticed Ms. Tree and Ms. Chief in the harbor. Here's a picture.
