The orbit\u2019s intended perigee, or low point, was at an altitude of 4,341 kilometers \u2014 or 2,697 miles \u2014 and an tilt of 26.75 degrees to the equator.<\/p>\n<p>Spacecraft separation occurred at 0402 GMT Monday (11:02 p.m. EST Sunday), and International Launch Services declared the launch a success.<\/p>\n<p>Based in Virginia, ILS is in charge of arranging commercial satellite launches on Russia\u2019s Proton rocket. ILS is a subsidiary of the Moscow-headquartered Khrunichev State Research and Production Space Center, which manufactures the Proton and Breeze M launch vehicle.<\/p>\n<p>\u201cIt is a true honor for ILS and Khrunichev to be entrusted with the launch of the Global Xpress network for industry innovator, Inmarsat,\u201d said Phil Slack, president of ILS. \u201cThe Inmarsat 5 F2 launch will enable ground breaking satellite communications connectivity via land, sea and air, as part of the three-satellite system launched by ILS Proton.\u201d<\/p>\n<p><iframe loading=\"lazy\" width=\"678\" height=\"381\" src=\"https:\/\/www.youtube.com\/embed\/A8pLaWdW0yI?feature=oembed\" frameborder=\"0\" allowfullscreen=\"\"><\/iframe><\/p>\n<p>Sunday\u2019s launch was the first of 12 planned Proton mission in 2015. Five or six of the launches are assigned to ILS for deployments of commercial communications satellites like Inmarsat 5 F2, an ILS spokesperson said.<\/p>\n<p>The Inmarsat spacecraft was built in El Segundo, California, by Boeing Satellite Systems International, and it carries its own chemical and electric propulsion system to maneuver into a circular orbit 22,300 miles over the equator in the coming weeks, where Inmarsat will complete testing of the platform and begin using it for commercial service.<\/p>\n<p>The Inmarsat 5 F2 satellite is about the size of a London double-decker bus, and it will extend power-generating solar panels to a span of 111 feet by the end of the month, Inmarsat said in a press release.<\/p>\n<p>The satellite should be on station in geostationary orbit by the end of March, Inmarsat said, and begin payload testing in early April.<\/p>\n<p>Furnished with 89 fixed and steerable spot beams, the satellite will be the second craft to launch for Inmarsat\u2019s Global Xpress service, which aims to boost connectivity speeds for customers on airplanes, at sea, and in other remote regions worldwide.<\/p>\n<p>\u201cThe successful launch of our second Inmarsat 5 satellite by Proton is a significant step forward on our journey to deliver the world\u2019s first globally available, high speed mobile broadband service,\u201d said Rupert Pearce, CEO of Inmarsat.<\/p>\n<p>\u201cThis is a great achievement and I would like to pay tribute to the skill and expertise of Inmarsat\u2019s engineering teams and all our employees involved in the design, development, manufacturing, testing and launch,\u201d Pearce said. \u201cIt is their dedication, alongside the outstanding support we have received from our manufacturing and launch partners \u2013 Boeing and ILS \u2013 which has helped deliver such a successful outcome.\u201d<\/p>\n<p>Inmarsat\u2019s previous satellites broadcast in L-band frequencies, but the company switched to Ka-band for the Global Xpress system, offering improved downlink communications speeds to 50 megabits per second, with up to 5 megabits per second on the uplink side.<\/p>\n<figure id=\"attachment_3459\" aria-describedby=\"caption-attachment-3459\" style=\"width: 620px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\" wp-image-3459\" src=\"http:\/\/spaceflightnow.com\/wp-content\/uploads\/2015\/01\/globalxrpess1.png\" alt=\"Artist's concept of a Global Xpress satellite.

Inmarsat engineers tracked ping signals the company\u2019s satellites received from the lost airliner and helped investigators conclude the plane likely went down somewhere in the southern Indian Ocean.<\/p>\n<p>No trace of the jet has been found.<\/p>\n<p>Inmarsat proposed a free global airplane tracking service in May 2014 for all commercial airplanes fitted with the the company\u2019s satellite transmitters.<\/p>\n<p>Inmarsat\u2019s first Global Xpress satellite launched in December 2013. Launches of the next two spacecraft were delayed after a Proton launch failure in May 2014 that left the booster grounded for four months.<\/p>\n<p>Russia sent up two government missions on Proton launches in September and October before the rocket returned to commercial service with a pair of flights for Gazprom Space Systems and SES in December.<\/p>\n<p>The Inmarsat 5 F1 spacecraft deployed in December 2013 covers the Indian Ocean, the Middle East, Europe and Africa. The satellite launched Sunday will be positioned at 55 degrees west longitude over the Atlantic Ocean and the Americas.<\/p>\n<p>The third Global Xpress satellite has completed ground testing and is due for liftoff in the second quarter of 2015, allowing Inmarsat to commence global service by mid-year. Boeing is manufacturing a spare fourth Inmarsat 5 satellite, with delivery expected in late 2016.<\/p>\n<p>But Inmarsat\u2019s clients are already using the Global Xpress system.<\/p>\n<p>\u201cOur first GX satellite entered commercial service in July 2014 and has since been delivering an excellent service to our customers in Europe, the Middle East, Africa and Asia,\u201d Pearce said. \u201cWith Inmarsat 5 F3 expected for launch by Proton in the coming months, we are on schedule to achieve full global coverage early in the second half of 2015.\u201d<\/p>\n<p>Britain\u2019s Sky News broadcasted the first live, on-air transmission through Global Xpress to support the networks\u2019s coverage of the Jan. 25 Greek election.<\/p>\n<p>\u201cGX represents a significant opportunity for media,\u201d said Martin Turner, director of media at Inmarsat Enterprise, in a press release. \u201cThe ability to live stream HD content to news-hungry audiences worldwide is crucial in a competitive industry and we are proud to be able to deliver a service that enables the world\u2019s media to do just that; no matter how remote their location. Reliability, speed and quality are of unique importance to our media customers and we will continue to deliver on these areas, supported by a suite of terminals, when the GX network becomes fully operational.\u201d<\/p>\n<p><b><i>Follow Stephen Clark on Twitter: @StephenClark1.<\/i><\/b><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Proton rocket lifted off from the Baikonur Cosmodrome at 1231 GMT (7:31 a.m. EST; 6:31 p.m. local time) Sunday.
