Tripod Data Systems Releases New TDS Locator Accessory Package 9.8.04
Tripod Data Systems (TDS) announced the release of its new TDS Locator accessory package. The package helps surveyors find the corners of properties that have overgrown or unmarked boundaries. TDS Locator can be used with TDS Recon data collectors that run Windows Mobile 2003 software for Pocket PCs.
The TDS Locator accessory package consists of TDS Locator software, a Recon Extended CF-Cap and a Holux CompactFlash GPS WAAS-capable receiver. Surveyors can purchase either a complete package or individual components. TDS Locator software can be used with most CompactFlash GPS receivers that output NMEA data strings. When used with a Holux GM-270 receiver receiving a WAAS signal, the TDS Locator has an accuracy of 2.2 meters. In non-DGPS mode, the accuracy range is from five to 25 meters.
The software's navigation display shows the route, waypoints, track, north arrow and target arrow. To begin a project, a surveyor can input either waypoints or a route-the calculation of bearings and distances from one corner to the next-from the property deed or title. The GPS receiver then leads the surveyor to a point near one property corner. Once the first corner is located, the surveyor can localize that point and navigate to the other corners.
Surveyors can use JPG background maps, such as aerial photos, with TDS Locator. The software can also display sky plots showing the relative position and signal strength from GPS satellites, along with HDOP values-helping users check the GPS signal.
