Abstract
A GNSS data collection system includes a pole mounted GNSS receiver and inclination sensors. A data collection module provides a data collection graphical user interface (GUI) visible on a hand-held data collector computer. The data collector computer is communicably coupled to the GNSS receiver and receives three-dimensional location data and inclination data for the range pole in real-time. A virtual level component uses the inclination data to display on the GUI real-time tilt information in the form of a virtual bubble level indicator. The inclination data and height of the range pole are used to calculate and display horizontal distance and direction to level the GNSS receiver, using: incline=sqrt(xtilt*xtilt+ytilt*ytilt) where, xtilt=the inclination data for the range pole along the x axis, ytilt=the inclination data for the range pole along the y axis, and horizontaldistancefromlevel=rh*sin(incline) where, rh=the height of the range pole.
