Horizons Satellite is a joint venture between Intelsat and SKY Perfect JSAT Group. Originally formed in 2001, pursuant to a memorandum of understanding between JSAT Corporation and PanAmSat for the launch of Horizons-1, it was renewed for Horizons-2. [1] [2] [3] [4] JSAT later merged into the SKY Perfect JSAT Group and PanAmSat was acquired by Intelsat, but the companies continued with the relationship, with the order for Horizons-3e. [5] Both companies also launched a joint satellite, Intelsat 15/JCSAT-85, but instead of the equal share agreement of this joint venture, JSAT owns a specific payload of 5 transponders out of the 22 Ku band transponders of the spacecraft.

History

On August 1, 2001, JSAT Corporation announced an equal share joint venture with PanAmSat, called Horizons Satellite. [1] [2] On September 4, 2001, it ordered from Boeing its first satellite, Horizons-1 / Galaxy 13 . It was a 4 t (4.4 tons) spacecraft with 24 C band and 24 Ku band transponders. It had a 10 kW power generation capacity and 15 years of expected life. [8]

On the same day of the satellite order, Boeing disclosed that it had received an parallel contract from PanAmSat, where the latter had exercised an existing option to launch Horizons-1 from its Sea Launch subsidiary. [9]

On October 22, 2002, JSAT and PanAmSat announced a joint sales agreement where JSAT's clients would gain access to PAS 2 and PAS 8, while PanAmSat's would get JCSAT-2A and JCSAT-3. [10] [11] A week later, on October 28, Horizons Satellites obtained permission to operate in Japan. [12]

Horizons-1 was successfully launched on October 1, 2003 aboard a Zenit-3SL rocket from the Ocean Odyssey platform in the Pacific. [13] [14] [15]

On June 27, 2005, JSAT and PanAmSat announced that they were renewing the partnership by ordering a second satellite, Horizons-2. This Ku band satellite would be positioned on the 74°West that belonged to PanAmSat. [3] [4]

On August 30, 2005, Orbital Sciences announced that Horizons Satellite had ordered a small satellite based on the STAR-2 platform, Horizons-2, for the PanAmSat licensed orbital slot at 74°West. It would carry 20 Ku band transponders, generate 3.5 kW of power, weight around 2.3 t (2.5 tons) and was expected to be launched in 2007. [16]

The August 2005 take over of PanAmSat by Intelsat, did not diminished the relationship and, in fact, strengthened the alliance. [5] On December 21, 2007, Horizons Satellite used an Ariane 5 rocket to launch Horizons-2. [17] And, outside of the Horizons Satellite, JCSAT and Intelsat launched the joint satellite Intelsat 15/JCSAT-85 on November 30, 2009 aboard a Zenit-3SLB. [7]

On November 4, 2015, JSAT and Intelsat made a joined statement that they would add a new member to their Horizons joint venture. The satellite, called Horizons 3e, would be based on the Intelsat EpicNG platform, featuring an optimized C band and high throughput Ku band payload it would offer mobility and broadband connectivity services in the Asia-Pacific region. [18] It was expected to use the 169°East orbital slot and launch by the second half of 2018. [19]

This would be the fourth joint satellite, along with the other two Horizons Satellite spacecraft, Horizons-1 and Horizons-2 and the separately co-owned JCSAT-85/Intelsat 15. Since this would be an investment within Horizons Satellite, it would not be considered a capital expenditure of the parent companies. [6]

Horizons Fleet

It has two satellites on-orbit Horizons-1 and Horizons-2, with a third, Horizons-3e planned for 2018.
