CAPE CANAVERAL \u2014 The massive U.S. Navy communications satellite launched from Cape Canaveral two weeks ago has completed prescribed maneuvers to reach geosynchronous orbit and successfully unfurled its umbrella-like antenna reflectors.<\/p>\n
Checkouts of the spacecraft \u2014 expected to last several months \u2014 are getting underway high above the Pacific Ocean testing location before the bird will be declared ready for service over the Atlantic Ocean.<\/p>\n
The craft will be capable of covering nearly a third of the planet to provide mobile communications to U.S. warfighters on the move.<\/p>\n
The Mobile User Objective System satellite No. 3 was lofted into space Jan. 20 by the United Launch Alliance Atlas 5 rocket, achieving a highly elliptical preliminary orbit as planned.<\/p>\n
From there, the Lockheed Martin-built satellite performed a series of 7 engine firings to circularize the orbit and reduce its orbital tilt closer to the equator. The burns, which ranged from 19 to 47 minutes in length, put the spacecraft into the proper geosynchronous orbit 22,300 miles up.<\/p>\n
After the orbit was reached, the following 36 hours saw the spacecraft achieve its \u201cflight configuration\u201d by executing critical deployments of the power-generating solar wings that now stretch 94 feet tip-to-tip and two gold mesh, umbrella-like antenna reflectors.<\/p>\n
The antennas provide the same type of Ulta High Frequency communications like previous Navy spacecraft and the other offers modernized capabilities that the new MUOS system will create.<\/p>\n
\u201cThis MUOS 3 launch is another major milestone to achieving the next generation of global tactical satellite communications capability for the Department of Defense,\u201d said Navy Capt. Joe Kan, MUOS program manager. \u201cIt\u2019s very visible evidence of the tremendous talent and dedication of our integrated joint service, government and contractor team.\u201d<\/p>\n
Coverage to legacy users will transmit through a 17.7-foot-diameter reflector on the bottom of the craft and the advanced, multi-beam features of MUOS to significantly increase the transmission capacity over the Navy\u2019s previous satellites will use a large 46-foot reflector atop MUOS.<\/p>\n
All U.S. military forces rely upon Navy satellites for Ultra High Frequency narrowband communications. UHF offers small, portable units that forces can carry into battle and the frequency enables communications in urban canyons and mountainous terrain, penetrating foliage and transmitting through bad weather.<\/p>\n
Each MUOS satellite has 16 times the capacity of the aging UHF satellite constellation.<\/p>\n
What\u2019s more, MUOS also creates a new \u201crugged smartphone\u201d network to provide 3G-like cellular telephone and data services across the globe when the constellation is fully launched in the next couple of years.<\/p>\n
Now begins several months of satellite system and payload testing before builder Lockheed Martin hands over the MUOS 3 craft to the government for additional checks in advance of setting it operational.<\/p>\n
\u201cThe MUOS operational capability will assure users, particularly those carrying radios in the field or while dismounted on patrol, secure on-demand voice and data communication services, both in point-to-point mode and through networked communications,\u201d said Vice Adm. Jan Tighe, commander of the U.S. Tenth Fleet.<\/p>\n
\u201cThis 24-7 on-demand satellite communication is the lifeblood U.S. forces to conduct operations around the world. Our teammates across the DoD can rest assured that we are operating MUOS as a warfighting platform, delivering capability when and where it is needed. Indeed the first of our five strategic goals at U.S. Fleet Cyber Command is to operate the Navy network \u2013 which includes Space assets \u2013 as a warfighting platform.\u201d<\/p>\n
MUOS No. 4 is set for launch in August aboard another Atlas 5.<\/p>\n","protected":false},"excerpt":{"rendered":"
