Pint-sized powerhouse

We’ve taken our already revolutionary GCX2 and delivered even more flexibility and functionality to meet the needs of your customers. Improvements include the addition of BeiDou and Galileo tracking capability, longer range base-to-rover communication, and never-seen-before performance in tree canopy situations. The GCX3 may look similar to the previous model but both the receiver board and the antenna element have been updated. Try it and see the difference.
