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 Share Data Between Two Data Collectors

Whether you're out in the field or working remotely, efficient data sharing can make a huge difference in your workflow. Fortunately, sharing a project between two Data Collectors is quick and easy — no cables, no manual transfers, just a few taps.

Here's a simple step-by-step guide to help you transfer project data smoothly.

📍 When Would You Need This?

You're working on a site with a teammate who needs the same project file
You're switching devices mid-task
You want to send a project to your colleague for review
Or, you're simply backing up data to another unit

✅ Step-by-Step: Sharing Your Project

Step 1: Open Project Manager
From the Project page, tap on Project Manager to view all your saved projects.

Step 2: Select the Project You Want to Share
Find the target project in your list, and tap Share.

Step 3: Get the QR Code or Sharing Code
Once you tap Share, the screen will display a QR code and a Sharing Code.

If the other device is nearby, just scan the QR code.
If not, copy and send them the Sharing Code.

Step 4: On the Second Device – Tap the '+' Button
On the receiving Data Collector, tap the ‘+’ icon at the top-right corner.

Step 5: Choose How to Receive the Data
You will see two options:

Scan QR Code
Sharing Code

Choose whichever works best for your situation.

Step 6: Enter the Sharing Code (if applicable)
If you're using the code method, type it in and tap OK.

Step 7: Download the Project
Once the shared project appears, tap Download to store it on the second device.

That's it — your project is now successfully shared!

💡 Pro Tips

Make sure both devices are connected to the internet
Rename your project before sharing if needed to avoid confusion

🧭 Final Thoughts

Seamless data sharing helps field teams stay in sync and work efficiently. Whether you're working on surveying, mapping, or site inspections, knowing how to share your project files easily can save time and reduce errors.
