Topcon G3 Technology
Topcon announced G3 satellite receiver technology with a Universal Signal Tracking system capable of tracking all GPS, GLONASS and future Galileo signals. To process multiple signals from multiple satellite systems, Topcon engineered the Paradigm-G3 chip. 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. In addition, the chip supports the entire Galileo signal structure, 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 <P>
