Laser GNSS: measuring points that are difficult to approach
A laser-capable GNSS workflow combines receiver positioning with another measurement, so both parts need validation.
A remote point depends on the whole measurement chain
Laser GNSS methods can help observe a point without placing the pole tip directly on it. The final coordinate depends on GNSS positioning, orientation, target identification and the laser measurement. Range alone is not a statement of final coordinate accuracy, especially as distance or aiming difficulty increases.

Test the target and geometry
The EQ20 brochure lists laser measurement up to 200 m and a separate distance-dependent accuracy specification. Review those conditions and compare a remote target against independent measurements. Follow the equipment instructions for laser use and confirm that the intended surface and observation geometry support the job.

Practical checklist
- Review range and accuracy as separate specifications.
- Check target visibility, aiming and surface behavior.
- Compare remote points with independent control measurements.
Plan your GNSS setup
Compare the EQ10 and EQ20 receiver specifications, then discuss the configuration and support your project needs.
