Getting started
1. Set up the base
Place the base over a known point or start it on an autonomous position, and confirm it is transmitting corrections.
2. Connect the rover
Link the rover by radio or NTRIP, and confirm a fixed solution before you measure anything.
3. Check into control
Measure a known point and compare — if it does not agree, stop and find out why before the job proceeds.
4. Work the job
Collect, stake or scan, and keep the raw files for post-processing and quality checks.
Guides & how-tos
RTK base and rover setup
Base placement, radio links and confirming a fixed solution.
NTRIP configuration
Network corrections over cellular — mountpoints, credentials and connection checks.
Tilt compensation
Using the tilt-compensated IMU (SL7: 60° tilt) so the pole does not have to be level.
Image measurement
Measuring from photos with the SL9 — 2–5 cm accuracy within 15 m of the camera.
SLAM-Fix switching
How the SL9 switches between RTK and SLAM when satellite signals drop out.
Satsurv field workflows
Survey, stakeout and coding in the Satsurv field app.
Post-processing with SGS 2.0
Static processing and baseline adjustment — SGS 2.0 handles 100+ baselines.
Site localization
Grid-to-ground calibration and local coordinate setup for the job site.
Troubleshooting
No fixed solution?
Check sky visibility, the correction link (radio or NTRIP) and the base position. Move clear of obstructions and re-initialize.
Heights do not agree?
Check the antenna height, the geoid model and the vertical datum — most height errors live in one of the three.
Radio link dropping?
Check antenna connections, channel and power settings, and line of sight between base and rover.
Tilt readings look wrong?
Re-calibrate the IMU on level ground and confirm the pole length entered in the software.
Points do not match control?
Re-check into a second known point. If both disagree the same way, suspect the base setup or the coordinate system.
