A GNSS data collection system includes a pole mounted GNSS receiver and inclination sensors. The range pole has an adjustable length and an integrated electronic measurement device to capture and provide length data. 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/or the electronic measurement device and receives three-dimensional location data, the length data, and inclination data for the range pole in real-time. The inclination data and height of the range pole are used to calculate and display horizontal distance and direction to level the GNSS receiver.

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.

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.

A Robotic Total Station (RTS) system includes an RTS disposed for at least two-axis rotation on a tripod, and a rover including a pole mounted prism and GNSS receiver with inclination sensors. The RTS rotates on the tripod to point towards the rover and generate an RTS-position measurement using an optical signal reflected by the prism. The RTS is communicably coupled to the data collector and/or the GNSS receiver, and receives and uses the GNSS-derived position measurements and the inclination data for the range pole in real-time, to automatically track and point the RTS towards the prism.

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=cos(cos(_tilt)*cos(_tilt))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, andhorizontaldistancefromlevel=*sin(incline)where,rh=the height of the range pole.

GNSS mobile base station and data collector with electronic leveling

A self-contained, hand-held, wireless engineering survey data collection system and method includes a survey data collector ruggedized to MIL-STD-810G, having a housing with a hand-held, tablet, form factor, and a processor, memory module, data storage, power source, and a full personal computer operating system. A user interface is supported by the housing and communicably coupled to the processor. A survey module configures the processor, memory module, data storage, and user interface to capture and store engineering survey data. Communications ports enable communication with peripheral devices. A survey-grade GNSS module configured for positioning accuracy within a margin of error of 3 cm, is supported by the housing and communicably couplable to the processor. An internal GNSS antenna is supported by the housing and communicably coupled to the GNSS module. The survey data collector is thus configured to capture engineering survey data including position data generated by the GNSS module.
