RTK Site Control & Construction Positioning
Plan fixed GNSS reference corrections for construction site control, layout checks and field inspection records. Select rugged field devices and validate the complete workflow against site control.
Connect field checks and layout activities to a documented reference installation. Choose handheld portability or a larger field tablet around the actual drawings, software and work posture.
The field challenge
Reference setup, project grids, changing obstructions and site equipment can affect field observations. Consistent source settings and acceptance checks help prevent different teams from working from inconsistent references.
A reference-to-field architecture
Use a GB30 complete kit at a stable reference point with the main unit indoors. Connect compatible rovers or selected RTK field devices to its NTRIP source. Review additional reference locations when the work area, baseline or visibility requires them.
Deployment example
The following illustrates a project workflow; it is not a report of a commissioned customer installation.
A civil contractor has survey staff checking positions at different parts of an active development. The team maintains one accepted site reference, distributes its correction source through GB30, and uses the approved field application to compare observations with project drawings and control points.
Agree the site reference
Confirm control coordinates, local grid or transformation requirements and the reference antenna installation.
Prepare the field workspace
Load the approved project data and verify the positioning input and output formats in the selected application.
Check representative locations
Evaluate known points at representative working distances and obstruction conditions before accepting the workflow.
Manage changes
Record changes to reference setup, site conditions and application configuration; revalidate after relevant changes.
Acceptance and handover
• Accepted project reference and independent control checks
• Correct project data, units, grid and height handling
• Usable display and controls in representative site conditions
• A documented process for reference changes and field handover
Define your quotation
• Which layout, surveying or drawing-review application is required?
• What grid, transformation and height convention must the workflow support?
• Does the team need a compact handheld, 8-inch tablet or larger G101M workspace?
Common project questions
Does RTKGO include construction layout or CAD software?
RTKGO covers correction connectivity and receiver status. Construction layout, CAD review and project-file support depend on the application selected for the device.
Is a larger tablet always the best choice?
No. Compare screen area, weight, mounting and carrying needs. G101M suits a larger field workspace; G80M is a smaller landscape alternative, while G60M prioritizes handheld portability.
Can one reference point cover every construction project?
Coverage and acceptable baselines depend on site size, conditions, installation and positioning requirements. Validate representative locations instead of assuming a fixed coverage radius.
Tie the RTK workflow to independent site control
Can this system support construction layout checks?
Compatible field applications and GNSS equipment may use GB30 correction data for layout and checking workflows. Confirm the site coordinate system, control points, antenna reference and task tolerances in the chosen software.
Which tablet suits detailed construction drawings?
Compare G101M for a larger field display and G80M for a more compact landscape body. Evaluate drawing readability, physical controls, carrying and mounting with the actual application.
