FARNBOROUGH, U.K., July 18, 2006 /PRNewswire/ -- Raytheon Company
successfully completed the Preliminary System Acceptance Test for the GPS
Aided GEO Augmented Navigation-Technology Demonstration System (GAGAN-TDS).
"This test was significant because the GAGAN-TDS ground elements
supplied by Raytheon were installed and integrated ahead of schedule," said
Andy Zogg, vice president of Raytheon's Airspace Management and Homeland
Security business. "More importantly, the system functioned properly and
exceeded the accuracy requirements.
"The performance on this test solidifies Raytheon's leadership position
in satellite-based navigation and continues a Raytheon track record of
successfully deploying software intensive networked systems."
The GAGAN-TDS network monitors the Global Positioning Satellite signals
for errors and then generates correction messages to improve the accuracy
of end-users' position solution. During the test period, average accuracy
was better than one meter (3.3 feet) horizontally and only slightly more
than one meter vertically, thus surpassing the 7.6 meter (25 feet)
requirement by a significant margin.
GAGAN-TDS is the first phase of a project sponsored by the Indian Space
Research Organization (ISRO) and Airports Authority of India (AAI) to
implement a space-based navigation system in Indian airspace. GAGAN is one
of several systems being deployed around the world as part of an initiative
endorsed by the International Civil Aviation Organization to help civil
aircraft transition to satellite-based signals from ground-based navigation
aids. The technology enhances navigation in all phases of flight, from
take-off through landing. Routes are more flexible and efficient, landing
safety is increased, and navigation service providers offer better guidance
at lower costs.
The GAGAN-TDS program consists of an Indian Monitor and Control Center
in Bangalore, an Indian Land Uplink Station also in Bangalore, and eight
Indian Reference Stations distributed throughout India. Raytheon supplied
the subsystems, installed the units in partnership with ISRO and AAI, and
then integrated the system through data links provided by ISRO and AAI.
With completion of the Preliminary System Acceptance Test, Raytheon
will next work with ISRO to integrate the ground elements to a
geosynchronous satellite. After integration, a signal-in-space broadcast of
the GAGAN-TDS messages will be demonstrated.
"We are very pleased with the cooperative effort among Raytheon, ISRO,
and AAI that led to this successful test," said Zogg. "The TDS phase of
this program demonstrated how to successfully deploy an SBAS in India, so
all of the participants are better prepared for the next stage of the
program."
