Hemisphere GPS Awarded Two New GPS Technology Patents

    CALGARY, Nov. 26 /CNW/ - (TSX: HEM) Hemisphere GPS, a leading designer
and manufacturer of advanced GPS products proudly announces that it was
recently awarded two new patents for innovative technology.
    The Method and System for Synchronizing Multiple Tracking Devices for a
Geo-Location System patent (U.S. Patent No. 7,292,186) enables more robust and
cost effective heading by using a single processor to compute heading from
multiple GPS receivers. Hemisphere GPS's Attitude Determination Exploiting
Geometry Constraints patent (U.S. Patent No. 7,292,185) increases the speed
and reliability of Real-Time Kinematic (RTK) solutions for multiple antennas
at known distances from each other. The entire system can be moving or
stationary while computing the RTK solutions.
    Hemisphere GPS customers are already reaping the benefits of the
technological advances recognized by these patents. These newly patented
techniques are currently part of the Company's successful Crescent(R) Vector
GPS technology and the recently announced Eclipse(TM) dual-frequency OEM
board. This Crescent technology is key to the superior performance of
Hemisphere GPS' Vector(TM) products including the V100 series, the VS100
series, and OEM derivatives. Vector products function like a GPS compass and
deliver greater precision than traditional heading solutions such as
gyrocompasses and fluxgate compasses. The V100 and VS100 series products are
specifically designed for marine navigation, hydrographic applications, and
antenna pointing applications.
    These software based patents are key components of the leading edge
Crescent and Vector GPS technologies, and allow Hemisphere GPS to offer high
accuracy and performance to its customers at extremely competitive prices.
    "We are very pleased to be awarded these new patents," says Dr. Michael
Whitehead, Chief Scientist of Hemisphere GPS. "Our commitment to providing our
customers with the most benefit and greatest value in application specific
solutions doesn't allow us to produce "one size fits all" products. These
patents are further evidence of our dedication to bring innovative technology
and optimized solutions to the marketplace."
