Lockheed Martin GPS III Satellite Prototype To Help Cape
Canaveral Air Force Station Prep For Launch
July 22, 2013
Lockheed Martin recently delivered a
full-sized, functional prototype of the next-generation Global
Positioning System (GPS) satellite to Cape Canaveral Air Force
Station to test facilities and pre-launch processes in advance
of the arrival of the first GPS III flight satellite.
The GPS III Non-Flight Satellite
Testbed (GNST) arrived at the Cape on
July 19 to begin to dry run launch base space vehicle
processing activities and other testing that future flight GPS
III satellites will undergo. The first flight GPS III
satellite is expected to arrive at the Cape in 2014, ready for
launch by the U.S. Air Force in 2015.
The GNST arrived at the Cape by Air
Force C-17 aircraft from Buckley Air Force Base near Lockheed
Martin's GPS III Processing Facility (GPF) in
Denver, Colo. Prior to shipment, the GNST
was developed and then completed a series of high-fidelity
activities to pathfind the integration, test and environmental
checkout that all production GPS III satellites undergo at
Lockheed Martin's new satellite manufacturing facility.
An innovative investment by the Air
Force under the original GPS III development contract, the GNST
has helped to identify and resolve development issues prior to
integration and test of the first GPS III flight space vehicle
(SV 01). Following the Air Force's rigorous "Back-to-Basics"
acquisition approach, the GNST has gone through the development,
test and production process for the GPS III program first,
significantly reducing risk for the flight vehicles, improving
production predictability, increasing mission assurance and
lowering overall program costs.
"We call the GNST a 'pathfinder'
because it has truly blazed the trail for every one of our GPS
III processes from initial development, production, integration
and test, and now pre-launch activities," explained
Keoki Jackson, vice
president for Lockheed Martin's Navigation Systems mission area.
"All future GPS III satellites will follow this same path, so
the GNST was a smart initiative to help us discover and resolve
any issues in advance, implement production efficiencies, and
ultimately save a tremendous amount of time and money in the
long run."
GPS III is a critically important
program for the Air Force, affordably replacing aging GPS
satellites in orbit, while improving capability to meet the
evolving demands of military, commercial and civilian users.
GPS III satellites will deliver three times better accuracy,
include enhancements which extend spacecraft life 25 percent
further than the prior GPS block, and a new civil signal
designed to be interoperable with international global
navigation satellite systems.
