H-Star Base Station Maps

Subfoot (30 cm) accuracies are now achievable with the new GPS Pathfinder® ProXH™ receiver with H-Star™ technology. To ensure subfoot (30 cm) accuracy when H-star processing you require 3 dual frequency base stations within 200 kilometers of your field location. Trimble has analyzed the worldwide base station network and produced maps that allow you to see if you are have the necessary base station coverage in your area. The base stations used in this analysis are publicly available dual frequency base stations in the Trimble base station list. More base stations may be available in your area. For details contact your local Trimble Dealer.
