Trimble introduced the R6 GPS system and Business Center Software as part of its connected survey site model. With GLONASS capability available through the R-Track technology Global Navigation Satellite System (GNSS) option, the Trimble R6 GPS system enables users to augment GPS and view more satellites for enhanced positioning success in challenging environments. The compact unit features a multi-channel, multi-frequency GPS receiver, antenna, data-link radio and battery. The Trimble R6 GPS system includes an advanced receiver powered by a new RTK engine. Communication options include an internal 450 MHz radio option for use as a cable-free base station, and an internal GSM/GPRS option for Internet connectivity and use as a rover in a Trimble VRS (Virtual Reference Station) network. The new Trimble Business Center Software enables users to import GNSS field data for processing and export to the design software of choice. The software performs data reduction, computation, QA/QC and network adjustments. It also provides field error correction tools, visualization tools and powerful spatial data management capabilities.
