Geodetic-grade GPS measurements for control networks — the invisible skeleton behind every road, pipeline and construction grid.
Service Overview
Millimeter Baselines, Kilometer Corridors
GPS survey establishes precise control points using multi-constellation GNSS receivers — RTK for real-time staking, static sessions for the highest-order baselines. Every network is adjusted by least squares and tied to national datum.
Contractors use our control for machine guidance, setout and deformation monitoring, confident that point 1 and point 1,000 agree.
- RTK rovers delivering ±2cm positions in real time
- Static & fast-static baselines for first-order control
- Machine-guidance localization for dozers, pavers & drills
What's Included
Control Products for the Whole Site
Control Networks
Adjusted primary and secondary stations with coordinates, heights and sketches.
Level Runs
Digital-level height transfer for drainage-critical works and flood mapping.
Deformation Monitoring
Epoch campaigns that detect millimeter movement in structures and slopes.
Localization Files
Calibrations formatted for Trimble, Leica and Topcon machine systems.
Process
How Control Networks Are Built
1
Network design
Station geometry is planned for redundancy — every point observed from multiple baselines.
2
Observation
Static sessions and RTK vectors are logged with fixed-ambiguity solutions only.
3
Adjustment
Least-squares adjustment with outlier testing; residuals must clear tolerance.
4
Handover
Monumented stations, coordinate schedules and machine files — plus a recovery diagram per point.
Often Combined With
Drone Survey
Control is what makes aerial mapping survey-grade — we do both.
