Topcon G3 160T

Overview

The Topcon G3-160T Eurocard offers state of the art positioning based on GPS, GLONASS and now Galileo satellite signals. The G3-160T is able to withstand 30 g acceleration and output precise position computations at a high rate.

Based on the Eurocard standard format, this power-packed board provides tracking of 20 satellites in dual frequency mode GPS and GLONASS and can be instantly transformed via simple software commands into:

• GD mode (L1 + L2 GPS)
• GG mode (L1 GPS & GLONASS)
• GGD mode (L1 + L2 GPS & GLONASS)

The G3160T Eurocard offers state of the art positioning based on GPS, GLONASS and now Galileo satellite signals. Designed for integrators who demand the ultimate in performance, the G3160T is able to withstand 30 g acceleration and output precise position computations at a high rate.
