One of world's largest agricultural machinery suppliers to integrate Hemisphere's GPS receivers and automatic steering systems throughout its product lines

CALGARY, Alberta, Canada - June 28, 2005 - (TSX:CSY) - Hemisphere GPS, a designer and manufacturer of GPS products used in more than 50 countries, today announced an agreement to design and supply high-performance GPS receivers and automatic steering systems to CLAAS KGaA mbH for use throughout CLAAS' extensive product lines and platforms including tractors, grain harvesters, forage harvesters and wide-area mowing machines.

CLAAS, including its AGROCOM precision farming division, is one of the world's largest agricultural machinery manufacturers. The German firm markets its products in more than 140 countries.

"CLAAS is a very significant OEM partner for us," said Hemisphere President Rick Heiniger. "Hemisphere already sells more GPS receivers to the agricultural sector than anyone else in the world, and this agreement with CLAAS solidifies our position as the market leader."

The receivers that Hemisphere - a wholly owned division of CSI Wireless Inc. - supplies to CLAAS will be optimized for a variety of machine-control applications including driving guidance, automatic steering and visual awareness. The receivers will feature Hemisphere's new proprietary Crescent(TM) technology so they can deliver higher update rates, noise-reduced raw measurements, more memory and higher process capability, to enable more advanced applications and sophisticated configurations.

CLAAS has been employing Hemisphere's Outback(R) S GPS guidance systems as the core technology in GPS-Pilot since CLAAS introduced the hands-free automatic steering system in Europe in late 2003.

"The quality, performance and functionality of Hemisphere receiver technology has really impressed our customers, and we are delighted to begin offering them a much broader range of Hemisphere products, on both a factory-installed and after-market basis," said Dr. Hermann Garbers, CLAAS' Executive Vice-President of Technology Quality. "Farmers are telling us that GPS receiver technology is essential for modern farming. Because Hemisphere is the world leader in GPS guidance and automatic steering systems for agricultural use, it is the ideal partner for CLAAS to meet our customers' needs."

One of Hemisphere's greatest strengths, Mr. Garbers added, is its Crescent(TM) receiver technology. Based on Hemisphere's new proprietary GPS chipset, Crescent technology achieves very high performance - especially in machine-control applications.

Crescent(TM) receivers feature:

- Hemisphere's exclusive Coast(TM) software that enables receivers to utilize old Differential GPS (DGPS) correction data for 40 minutes or more without significantly affecting the accuracy of positioning - a big advantage during temporary signal blockages or outages

- Optional e-Dif(R) software available exclusively from Hemisphere that enables receivers to achieve Differential-quality positioning accuracies without needing an external DGPS signal - ideal for regions where Differential broadcasts are not available or available only by subscription

- Low power consumption - ideal for mobile and battery-powered applications

- Outstanding performance in DGPS environments

- Small size for versatile integration
