Trimble today introduced its high-accuracy Global Positioning System (GPS) receivers for Geographic Information System (GIS) data collection and mapping. The GPS Pathfinder® ProXH™ receiver is a high-performance integrated GPS receiver, 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 powerful new H-Star™ technology to provide subfoot (30 centimeter) positioning accuracy, making it the highest performing GPS receiver for mapping on the market today.   The ProXH receiver is 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 recent years, these industries have experienced increased requirements for sub-foot accuracy which, in the past, could only be addressed by long location occupation times or the use of survey grade systems that deliver a much higher accuracy than required.   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.   “The new GPS Pathfinder Pro series provides mapping and GIS professionals with a reliable high accuracy solution that is cost effective,” said Alan Townsend, vice president and general manager of Trimble Field Solutions. “These new products, along with the revolutionary H-Star technology, are part of Trimble’s continued commitment to provide customers with innovative solutions to meet their specific needs.”   Trimble H-Star technology is a combination of the ProXH receiver technology, field data collection techniques and post-processing that allows users to achieve better 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. The GPS Pathfinder Pro series is expected to begin shipping in May 2005. The receivers are available for purchase now from Trimble’s worldwide dealers and business partners.
