GNSS receivers for survey and layout
Choose with evidence
Choose around your field tasks, site conditions and deliverables. Review the receiver, controller, software and corrections as one system.
Start with the job
- What do you need to measure or set out?
- Which receiver, controller and office software do you already use?
- Will you use a correction network or your own base?
- What tolerances, coordinate system and output files does the project require?
Compare GNSS capture methods
| Model | Capture method | Best for |
|---|---|---|
| CHCNAV i89 | GNSS, tilt compensation and dual-camera visual surveying | Daily rover work where compact size and visual point capture are useful |
| CHCNAV i93 | GNSS, tilt compensation and dual-camera visual surveying; integrated 4G | A crew that values longer operating time, integrated connectivity or using the receiver in rover and base roles |
| CHCNAV i85 | GNSS with an aimed laser rangefinder and cameras | Repeated discrete points where a pole cannot safely reach and the target can be aimed at |
| CHCNAV ViLi i100 | GNSS, vision and LiDAR with SFix positioning | Obstructed-site work, batch contactless points or on-site point-cloud tasks |
