SureTopo™ is the Topcon proprietary patent-pending method to detect and filter out randomly appearing anomalous RTK coordinates resulting in storing of a point with shifted coordinates. Such anomalies occur more often in challenging environment conditions. When enabled, this method works automatically in RTK / Network RTK survey, requires minimum to none user involvement, works under hard conditions with default or even relaxed RTK survey settings and prevents spending long time in waiting for initialization of RTK engine with stricter settings.
SureTopo™ detects and filters out anomalous RTK coordinates right in survey and MAGNET Field stores a point with accurate coordinates with nearly zero chance to accept anomaly with shifted coordinates. No post-processing and no manual point filtering required. SureTopo™ uses automatically recorded series of RTK coordinates for a point, automatically resets both GNSS tracking and RTK engine between records and processes these coordinates with the proprietary filtering algorithm before MAGNET Field stores a point to the current job.
Note: Keep the GNSS antenna in a fixed position when surveying a point. Alternatively, use a GNSS receiver with TILT™ (Topcon Inertial Leveling Technology) feature.
To enable or disable SureTopo™ for anomalous RTK coordinates filtering:
Note: Formation of groups with coincided RTK coordinates by SureTopo™ displays in real time along with epoch counter when storing a point.
