Lockheed Martin wraps up practical testing of subsequent-gen GPS III satellite tv for pc techniques
Lockheed Martin flipped the change on its first (nonetheless Earth-sure) GPS III satellite tv for pc earlier this yr, and it is now introduced that it is accomplished practical testing on the satellite tv for pc’s key digital techniques. In a press launch, the corporate says these techniques, starting from navigation and management to communications, are all “functioning usually and prepared for ultimate integration with the satellite tv for pc’s navigation payload,” and that the satellite tv for pc stays on monitor for deliverly to the Air Pressure in 2014. As beforehand detailed, the satellites themselves are promising to ship a variety of enhancements over present GPS know-how to civilian and army customers alike, together with 3 times larger accuracy and an eight-fold improve in anti-jamming capabilities, which Lockheed Martin says is designed to “outpace rising international threats that would disrupt GPS service.”
Lockheed Martin Completes Practical Testing of First GPS III Satellite tv for pc Bus Digital Methods
DENVER, June 5, 2013 – A Lockheed Martin [NYSE: LMT]-led business staff has accomplished profitable useful integration exams of the spacecraft bus and community communications gear on the primary satellite tv for pc of the subsequent era International Positioning System, referred to as GPS III.
The current testing of GPS III area car 1 (SV 1) bus – the portion of the area car that carries mission payloads and hosts them in orbit – assured that each one bus subsystems are functioning usually and prepared for remaining integration with the satellite tv for pc’s navigation payload. Techniques examined included: steerage, navigation and management; command & knowledge dealing with; on-board pc and flight software program; environmental controls; and electrical energy regulation. The SV 1 satellite tv for pc’s community communication gear subsystem that interfaces with the bottom management phase and distributes knowledge all through the area car additionally handed all checks as anticipated.
This milestone follows February’s profitable preliminary energy-on of SV 1, which demonstrated the electrical-mechanical integration, validated the satellite tv for pc’s interfaces and led the best way for practical and hardware-software program integration testing.
“The profitable completion of the SV 1 bus practical take a look at validates that the spacecraft is now prepared to start the subsequent sequence of payload integration and environmental testing, previous to supply,” defined Keoki Jackson, vice chairman of Lockheed Martin’s Navigation Techniques mission space.
GPS III SV 1’s navigation payload, which is being produced by ITT Exelis, will probably be delivered to Lockheed Martin’s GPS Processing Facility (GPF) close to Denver later in 2013. The hosted nuclear detection system payload has already been delivered and mechanically built-in. The satellite tv for pc stays on schedule for flight-prepared supply to the U.S. Air Pressure in 2014.
GPS III is a critically essential program for the Air Pressure, affordably changing getting older GPS satellites in orbit, whereas enhancing functionality to satisfy the evolving calls for of army, business and civilian customers. GPS III satellites will ship 3 times higher accuracy and – to outpace rising international threats that would disrupt GPS service – as much as eight occasions improved anti-jamming sign energy for extra resiliency. The GPS III may even embrace enhancements including to the spacecraft’s design life and a brand new civil sign designed to be interoperable with worldwide international navigation satellite tv for pc techniques.
Lockheed Martin is presently underneath contract for manufacturing of the primary 4 GPS III satellites (SV 1-four), and has acquired superior procurement funding for lengthy-lead elements for the fifth, sixth, seventh and eighth satellites (SV 5-eight).
The GPS III staff is led by the International Positioning Techniques Directorate on the U.S. Air Drive Area and Missile Methods Middle. Lockheed Martin is the GPS III prime contractor with teammates ITT Exelis, Common Dynamics, Infinity Techniques Engineering, Honeywell, ATK and different subcontractors. Air Pressure Area Command’s 2nd Area Operations Squadron (2SOPS), based mostly at Schriever Air Pressure Base, Colo., manages and operates the GPS constellation for each civil and army customers.
Headquartered in Bethesda, Md., Lockheed Martin is a worldwide safety and aerospace firm that employs about 118,000 individuals worldwide and is principally engaged within the analysis, design, improvement, manufacture, integration, and sustainment of superior know-how methods, merchandise, and providers. The Company’s internet gross sales for 2012 have been $forty seven.2 billion.
