Lockheed Martin powers on second GPS III satellite in production

The Lockheed Martin team developing the U.S. Air Forces next generation Global Positioning System recently turned on power to the bus and network communications equipment payload of the programs second satellite designated GPS III Space Vehicle 2 (SV-02).

The successful powering on of GPS III SV-02, on Dec. 19, 2013, at Lockheed Martins Denver-area GPS III Processing Facility, is a major production milestone which demonstrates the satellites mechanical integration, validates its interfaces, and leads the way for electrical and integrated hardware-software testing.

ìThe GPS III SV-02 bus power on is a significant milestone, positioning SV-02 in line with the Air Forces first GPS III space vehicle, SV-01, in our GPF, where both satellites are progressing through sequential integration and test work stations specifically designed for efficient and affordable satellite production,î explained Mark Stewart, vice president for Lockheed Martins Navigation Systems mission area.

On Nov. 11, 2013, the propulsion core module for SV-02 was delivered to the GPF from Lockheed Martin’s Space & Technology Center, in Stennis, Miss., where the core was manufactured. The structural backbone of the satellite, the core contains the integrated propulsion subsystem that allows the GPS III to maneuver on orbit immediately after launch, as well as to conduct repositioning maneuvers throughout its mission life.

The GPS III program will affordably replace aging GPS satellites, while improving capability to meet the evolving demands of military, commercial and civilian users. GPS III satellites will deliver three times better accuracy; provide up to eight times improved anti-jamming capabilities; and include enhancements which extend spacecraft life 25 percent further than the prior GPS block. The GPS III also will carry a new civil signal designed to be interoperable with other international global navigation satellite systems, enhancing civilian user connectivity.

Lockheed Martin is currently under contract for production of the first six GPS III satellites (SV 01-06), the first four funded under the original contract and the fifth and sixth recent fully funded by an exercised Air Force option on Dec. 13, 2013. Lockheed Martin had previously received advanced procurement funding for long-lead components for the fifth, sixth, seventh and eighth satellites (SV 05-08).

The first GPS III satellite (SV-01) was powered on in Feb. 28, 2013. GPS III SV-01s spacecraft bus and antenna assemblies were delivered to Lockheed Martins GPF this summer. SV-01 is now in the integration and test flow leading to delivery ìflight-readyî to the Air Force.

The GPS III team is led by the Global Positioning Systems Directorate at the U.S. Air Force Space and Missile Systems Center. Lockheed Martin is the GPS III prime contractor with teammates Exelis, General Dynamics, Infinity Systems Engineering, Honeywell, ATK and other subcontractors. Air Force Space Commands 2nd Space Operations Squadron, based at Schriever Air Force Base, Colo., manages and operates the GPS constellation for both civil and military users.
