What is the accuracy difference between Fixed and Float RTK?

Fixed RTK typically delivers ±8 mm horizontal and ±15 mm vertical accuracy. Float RTK carries ±300–1000 mm of positioning error depending on baseline length and atmospheric conditions.

Why does my RTK show Fixed but coordinates are still wrong?

Common causes are a datum mismatch (wrong coordinate system), an incorrect geoid model applied to elevation, or an antenna height entry error.

How do I know if multipath is affecting my survey?

Multipath typically shows as unstable repeated measurements — the same physical point measured three times gives results differing by 20–50 mm rather than the expected ±8 mm.

Can I survey during ionospheric storms?

RTK accuracy degrades during geomagnetic storms (Kp index above 5). For precision engineering or cadastral surveys, postpone sessions until the Kp index drops below 3.

What is the maximum reliable CORS baseline for centimetre accuracy?

Most CORS networks guarantee ±10–20 mm horizontal accuracy within 50 km of the nearest reference station. Beyond 70 km, deploy a self‑deployed base station within 15 km of the survey area.

How to Use Laser Survey and AR Stakeout with AP30 Laser

Laser survey and AR stakeout are powerful tools for improving accuracy and efficiency in the field. With the AP30 Laser, you can easily perform point surveys and stakeouts using both laser targeting and augmented reality. This guide walks you through the step-by-step process.

🔧 Step 1: Connect the Device

To begin, connect your device to the AP30 Laser:

Go to the Device page and tap Communication.
Set the Model Type to AP30 Laser.
Connect to the AP30 Laser via Bluetooth.

Once connected, you're ready to start your laser survey.

🔦 Step 2: Start Laser Survey

Go to the Survey page and select Point Survey.
Enter the correct pole height and turn on IMU (inertial navigation).
Tap the laser icon to turn on the laser.
Aim the laser at the point you want to measure and tap Measure to record the position.

The laser must be precisely aligned with the target point for accurate results.

📸 Step 3: Use Front Camera for Long-Distance Targeting

When the laser dot is too far away to be seen by the naked eye, the front camera can assist you.

Tap the Aim icon.
Connect to the AP30 Laser's Wi-Fi.
Once connected, tap Aim again to launch the front camera.
Use the camera view to help locate the laser spot on distant objects.

🧭 Step 4: Use AR Stakeout with Bottom Camera

Return to the Survey page and select Point Stakeout.
Choose the point(s) you want to stake out.
Tap Stakeout to enter the stakeout interface.
Tap the AR icon at the bottom of the screen to activate AR stakeout.
Follow the on-screen arrows and instructions to move toward your target location.

Make sure your device is connected to the AP30 Laser's Wi-Fi before using any camera-based features.

📌 Notes

Wi-Fi connection is essential for using both the front and bottom cameras.

With laser accuracy and augmented reality guidance, fieldwork becomes faster, smarter, and more intuitive. Whether you're surveying hard-to-reach points or guiding stakeout with AR, the AP30 Laser makes it all easy.
