Hemisphere GPS, a Division of CSI Wireless, Introduces New High Accuracy, Multipurpose Crescent DGPS Receivers

Calgary, Alberta - November 14, 2006 - (TSX:CSY): CSI's Hemisphere GPS division, a designer and manufacturer of GPS products used in more than 50 countries, has announced the introduction of its new Crescent(tm) R100 Series DGPS Receiver. The Crescent R100 is the ideal solution for professional mapping, guidance and navigation applications. It joins the Crescent A100 Smart Antenna, Outback S2 and Outback BaseLine as the latest development to take advantage of Hemisphere GPS' powerful Crescent technology.

"The Crescent R100 Series is an example of the continuous portfolio of innovation we are achieving under our GPS focused strategy," said Steven Koles, President and CEO of Hemisphere GPS. "The Crescent R100 Series will be a key offering for us as we expand into new market segments".

Powered by Hemisphere GPS' Crescent technology, the R100 Series
o 12 Channel L1 GPS receiver with code and phase measurements
o Reliable DGPS positioning under 60 cm with an output rate of up to 20 times per second
o Especially fast start-up and signal reacquisition times
o Simple user interface and status lights allows easy configuration and receiver monitoring
o Available with several options for DGPS sources including Satellite Based Augmentation Systems (WAAS, EGNOS, etc.), Radio Beacon and OmniSTAR corrections
o Compatible with our exclusive L-Dif technology, for applications requiring accuracy under 20cm
o Radar-simulated pulse output provides accurate ground speed

These portable and versatile receivers also features Hemisphere GPS'
exclusive COAST(tm) and e-Dif (r) technologies. COAST software enables Hemisphere GPS receivers to utilize old differential GPS correction data for 40 minutes or more without significantly affecting the quality of positioning. When using COAST, the user is less likely to be affected by differential GPS signal outages due to signal blockages, weak signals or interference. No competing products offer this flexibility.

e-Dif technology enables Hemisphere GPS receivers to achieve DGPS-quality positioning accuracies without the need for a differential signal. It is ideal for locations where other differential services are limited or expensive. The Crescent R100 Series will replace the SLXg3 and MAX Series of receivers.

The release of these new Crescent-based products has aided Hemisphere GPS' ability to enhance its presence geographically in strategic markets such as Australia and South America, where its restructured distribution channels recently generated $2 million in purchase orders for Crescent-based products that are expected to be completed before the end of the Company's second quarter in June 2007. Higher sales in the Southern Hemisphere are important to the Company in helping offset seasonality within the business.
