Trimble introduced new high-accuracy GPS receivers for GIS data collection and mapping: the GPS Pathfinder ProXH and ProXT. The GPS Pathfinder ProXH receiver is a high-performance integrated GPS receiver, with antenna and battery all in a compact and lightweight unit. The ProXH receiver uses Bluetooth technology for cable-free communications to a field computer and Trimble's new H-Star technology to provide subfoot (30-centimeter) positioning accuracy. The ProXH receiver is ideally suited for use in high accuracy mapping, data collection and asset management such as water/wastewater, utilities, cadastral, telecommunications, transportation as well as construction and engineering applications. In addition to the ProXH receiver, the all-new GPS Pathfinder Pro series also includes the ProXT receiver. In the same convenient form factor as the ProXH, the ProXT receiver delivers submeter accuracy. Trimble H-Star technology is a combination of the ProXH receiver technology, field data collection techniques and post-processing that allows users to achieve subfoot accuracy. With the addition of an external Zephyr antenna, eight-inch (20-centimeter) accuracy can be obtained. The ProXH and ProXT receivers come with a variety of mounting options-belt, backpack, range pole or on a vehicle. (Trimble, Sunnyvale, Calif.).
