TCS Continues to Drive Wireless Innovation With Patent for Assisted GPS Precise Location Determination13 January 2006
TeleCommunication Systems, Inc. (TCS)
(NASDAQ: TSYS), a global leader in mission critical wireless
communications, today announced that the U.S. Patent and Trademark Office
has issued patent number 6,985,105 titled, "Improved Culled Satellite
Ephemeris Information Based On Limiting a Span of an Inverted Cone for
Locating Satellite In-Range Determinations." This invention relates to
location services for the wireless industry.
This patent is for an innovative method and algorithm for determining
precise locations using Assisted Global Positioning System (A-GPS)
technology within a Global System for Mobile Communications (GSM) network,
and can be applied to Code Division Multiple Access (CDMA) networks as
well.
As the cellular industry continues toward providing more precise
location-based services, the latest TCS patent offers an efficient method
for delivering these capabilities, while requiring minimal additional
infrastructure investment by mobile operators. It is another indicator of
the company's market leadership role in developing technology for wireless
E9-1-1 and precise location solutions. The patent describes a method for
enhancing the speed and efficiency of providing the precise location of
mobile phones for commercial and emergency services.
"This patent is another example of innovation by TCS engineers to create
cost-effective location-based wireless telecommunications services," said
Drew Morin, Senior Vice President and Chief Technology Officer for
TeleCommunication Systems. "As the industry looks for solutions that solve
their positioning and location challenges, TCS continues to provide
leadership with its patented technologies."
TCS currently holds forty (40) patents, and has nearly one hundred (100)
additional patent applications pending in the United States and worldwide.
About the Invention
Today, there are twenty-nine satellites in the GPS network, each moving
around the earth approximately six times per day. As a user moves his or
her wireless GPS device from one location to another, the locations
relative to the satellites change. GPS devices attempting to determine
their position can only communicate with a limited number of the total GPS
satellites at any given time. In the past, the time required for lock-in
and location determination using a conventional GPS receiver could take
several minutes, which is unsatisfactory for many applications, and a
longer time than the average wireless phone call's duration. Rapid, high
strength links to the satellites directly in line in a narrow cone path can
expedite the time to lock in a location.
In accordance with the principles of the present invention, a plurality of
locating satellites is culled into a sub-plurality for communication by a
plurality of wireless devices. A first inverted cone is defined above a
first site and then a second inverted cone is defined above a second site.
If the second site is farther from the equator than the first, then the
second inverted cone is made to have a base angle larger than the base
angle of the first inverted cone. If the first site is farther from the
equator than the second, then the first inverted cone is made to have a
base angle larger than the base angle of the second inverted cone.
Any sites used as reference points other than the first or second will have
inverted cones defined above them with base angles greater than, equal to,
or less than the inverted cones above the first and second sites, depending
on whether those other reference points are farther, equal or closer to the
equator than either the first or second sites.
