Hemisphere GPS' Crescent(TM) R100 Series RTK Technology Now Shipping


Calgary, AB - July 17, 2007- (TSX:HEM) Hemisphere GPS, a designer and manufacturer of advanced GPS products, announced today that their Crescent R100 Series DGPS Receivers now support RTK (Real-Time Kinematic) and is in full production release and available as an upgrade to all customers. Using Hemisphere GPS' patented RTK technology, Crescent R100 Series Receivers use both GPS and SBAS (WAAS/EGNOS/MSAS) to provide rapid initialization, improved reliability, and real-time centimeter level accuracy. For professionals in fields such as survey, GIS, precision agriculture, and dredging, this technological advance translates to an extremely accurate, versatile, and robust positioning solution at a fraction of the cost of traditional dual-frequency RTK systems.

"By applying our Crescent RTK Technology to our Crescent R100 Series Receivers, Hemisphere GPS is not only meeting the demands of the marketplace for accuracy and affordability, we are also setting the standard for the industry," said Steven Koles, President and CEO of Hemisphere GPS. "No other product on the market offers the flexibility and value of our Crescent R100 Receivers".

In addition to the new RTK feature, Crescent R100 Series multipurpose receivers also feature an L-Dif 20cm option and Hemisphere GPS' exclusive COAST(TM) and e-Dif® technologies. These receivers also support many differential correction options including SBAS, Radio Beacon, and OmniSTAR®. USB communication and a powered serial port for Bluetooth dongle support will also be available soon.

"We have packed these portable receivers with features that allow them to provide accurate GPS positioning, in almost any environment, anywhere in the world," added Mr. Koles.
