WASHINGTON — Hong Kong-based satellite fleet operator AsiaSat said July 31 that its next satellite will launch Sept. 28 on a Proton rocket from the Baikonur Cosmodrome in Kazakhstan.

The satellite, AsiaSat-9, has been in storage with manufacturer Space Systems Loral since passing its pre-ship review in April, AsiaSat said.

The launch, arranged by International Launch Services, the commercial arm of Proton manufacturer Khrunichev, will be the third commercial Proton launch this year. ILS spokesperson Karen Soriano told SpaceNews July 31 that Hispasat’s Amazonas 5 is ahead of AsiaSat-9 in Proton’s launch queue. She declined to say when the Amazonas-5 launch would occur.

AsiaSat-9 is a replacement satellite for AsiaSat-4, a C- and Ku-band telecommunications satellite from Boeing that launched in 2003. Compared to its predecessor, AsiaSat-9 carries a high-throughput Ka-band payload, a higher power C-band payload, and Ku-band beams that are “cross-strapped” to allow uplinks and downlinks between themselves.

Proton conducted its first launch in nearly a year on June 7, orbiting the EchoStar-21 satellite for Englewood, Colorado-based fleet operator EchoStar. An upper stage anomaly in 2016 that didn’t cause a failure but did spark an intense mission review, and the later discovery of an unusual solder in several upper stage engines, sidelined the rocket for about 12 months.

“With our newest satellite AsiaSat 9, we are primed to serve existing customers and new users as we reach a new milestone, presenting more cost-efficient opportunities, enhanced quality and faster services for applications through mobility, broadband data networks, and DTH [direct-to-home] services,” Andrew Jordan, AsiaSat president and CEO, said in a prepared statement July 31. “As we have broadened our scope and innovated to provide advanced satellite solutions, we are confident in the opportunities satellite services create for future broadcasting and communications throughout the Asia-Pacific region.”

AsiaSat-9 includes new coverage for Myanmar, where AsiaSat-customer KBZ recently expanded capacity on AsiaSat-4 and -7 for broadband connectivity, as well as new coverage for Indonesia and Mongolia. The satellite’s footprint will cover the Asia-Pacific region from 122 degrees east.
