Livermore, Calif., Dec. 29, 2005 - Revolutionary technology developed by Topcon Positioning Systems came closer to being used on job sites worldwide December 28 when the first satellite in the European Union's Galileo navigation program was launched.

For Topcon users, the launch - and the launch of three additional GLONASS satellites on Christmas Day - puts the spotlight on the company's Paradigm G3 chip - a groundbreaking new technology for satellite positioning systems. This pioneer development is the first satellite receiver technology with Universal Signal Tracking, a system capable of tracking all signals from all three satellite positioning systems: GPS, GLONASS, and Galileo.

Topcon developed G3 to provide access to Galileo satellites being launced by the European Space Agency, and new signals that will result from the modernization of the GPS constellation. Topcon products currently offer GPS+ technology, enabling access to both U.S. GPS and Russian GLONASS satellite systems.

To process multiple signals from multiple satellite systems, Topcon engineered the new Paradigm-G3 chip at its Moscow Technology Center. It is capable of receiving GPS L1, L2 and L5 carrier frequencies; C/A and L2C civilian codes; and P-code on both L1 and L2 frequencies. It also receives GLONASS signals including L1 and L2 carrier frequencies and L1 / L2 C/A and P-codes. The entire Galileo signal structure is supported, including L1, E1, E2, E5, and E6 signals. The advanced design features 72 tracking channels and operates with minimal power consumption.

The new chip will be the basis for a new generation of Topcon GPS+ products and will first appear in the new Net-G3 reference receiver, providing network hardware ready to support all satellite signals for the highest possible service to all networks users into the future.
