Now included on all new Topcon 9 Series robotic total station systems, Topcon’s X-Trac 7 enhances robotic tracking by using a tracking beam sequence that keeps the instrument crosshairs focused on the moving prism pole. The X-Trac 7’s internal firmware also performs advanced calculations to determine and track the prism. Topcon redesigned its RC-3 remote control by increasing the RC-3’s sensor speed and accuracy to take advantage of X-Trac 7. Users control X-Trac 7 via the TopSURV 7.2 interface software.
