By comparison, SiRF's highly acclaimed StarIII chip is a 20-channel receiver, and most people are still using GPS devices with 12-chanell receivers in them. The handle/battery compartment is designed to keep the center of gravity as low as possible, and the squared design prevents the unit from rolling around. They called it the GR-3 because it's the first receiver to support all three satellite systems: GPS, Glonass, and Galileo. It also boasts Bluetooth, and can optionally support GPRS.

The GR-3 is aimed at the lost-at-sea crowd, but those kinds of specs make me wish I could strap one to my car. Oh, and the GR-3 will set you back a paltry $22,000. Get the full details from Topcon's site.
