TDS Locator, running on the TDS Recon with Windows Mobile 2003 for Pocket PCs, was designed for professional surveyors, to assist in finding property corners. TDS Locator is especially helpful for longer boundaries and situations where the monumentation may be difficult to see. The navigation display shows the route, waypoints, track, north arrow and target arrow. Simply input either waypoints or a route from the property deed or title and the GPS receiver leads you to a point near one property corner. Once you locate the first corner, you can localize that point and navigate to the other corners.
TDS Locator can be used with most CompactFlash GPS receivers that output NMEA data strings”it can also work with receivers with WAAS capabilities. 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. You can also use JPG background maps, such as aerial photos, with the TDS Locator. The software can also display sky plots showing the relative position and signal strength from GPS satellites, along with HDOP values, so you can check the GPS signal.
You can get TDS Locator in an accessory package that includes a Recon Extended CF-Cap, a Holux CompactFlash GPS WAAS capable receiver and the Locator software. The components can also be purchased separately.
