Boeing Press Release
EL SEGUNDO, Calif., Feb. 20, 2017 – Boeing [NYSE: BA] will build a 702 satellite to expand communication for mobile telephone, data and internet users throughout the Asia-Pacific region.

The satellite, owned and operated by SKY Perfect JSAT Corporation and Kacific Broadband Satellites, has two distinct payloads. The JCSAT-18 payload will improve mobile and broadband services for SKY Perfect JSAT Corporation customers in Asia Pacific including Far East Russia. The Kacific-1 payload for Kacific Broadband Satellites will provide high-speed Ka-band satellite broadband internet to more than 20 countries in South East Asia and the Pacific.

JCSAT-18/Kacific-1 is scheduled to launch in 2019.

“The scalable Boeing 702 satellite is a flight-proven design that we are evolving to meet the future needs of our customers,” said Mark Spiwak, president of Boeing Satellite Systems International. “The combined JCSAT-18 and Kacific-1 satellite has the flexibility to accommodate various business requirements to meet the needs of both SKY Perfect JSAT and Kacific.”

Since the 1980s, Boeing has built 10 satellites for the JSAT Corporation and Space Communications Corporation, both now part of SKY Perfect JSAT Corporation.

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.

[SpaceNews] SpaceX wins Kacific, Sky Perfect Jsat condosat launch, new or used rocket TBD
Quote
In a Sept. 5 statement to SpaceNews, Kacific said the operator and Sky Perfect Jsat have yet to decide whether the launch will use a new or pre-flown Falcon 9.

“We have not yet made that decision, and will do so with our launch partners,” Kacific said.

The Boeing satellite factory has announced that the Kacific-1 satellite construction has moved into initial testing stages. The satellite is owned by Kacific, a private company registered in Vanuatu, and is scheduled for launch in 2019. The satellite will offer broadband services for Vanuatu customers and to the Pacific islands.

Boeing has started integration and testing of the Kacific-1 payload, which consists of the communications electronics. It has also started integration and testing of the satellite platform which includes the power and propulsion systems. The communications antennas are being prepared for range tests starting in the next few weeks.

[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?

Because the Falcon Heavy Test Flight was successful, it has inspired thousands of people to consider changing the future of space travel.

Or talk the customer in to launching it on FH.

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.
