POS TG™ IS A PRECISION MEASUREMENT SYSTEM DESIGNED TO
COMPUTE TRACK GEOMETRY
Integrating inertial sensors with GPS receivers and an optical gauge measuring system (OGMS), POS TG is a highly accurate and cost
effective alternative to traditional measurement technologies.

GPS Dropout Immunity - All track geometry, navigation, and dynamics output are continuous during GPS/DGPS or RTCM dropouts. Accuracy of track
geometry outputs is essentially unaffected during drop out intervals.
