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 Do Equal Distance Stakeout with RTK — Step-by-Step Guide

If you've ever needed to divide a line into equal parts for construction, mapping, or surveying work, the Equal Distance Stakeout function in your RTK is a real time-saver.
In this post, I'll walk you through each step — it's super simple even if you're new to RTK surveying!

🛰 Step 1: Go to the Survey Interface

Open your RTK and go to the Survey interface.
Tap "Point Survey", and collect the start point and end point of the line you want to divide.
These two points will be the base for your equal distance calculation.

⚙️ Step 2: Open Equal Point Calculation

Next, go to the Tool interface, and tap "Equal Point Calculation."
Here, you'll need to select the start and end points that you just measured.

📏 Step 3: Set the Number of Segments

You'll see a box labeled "Number of segmentation."
This is where you decide how many equal parts you want to divide the line into.
For example, if you want 10 equal sections, just type 10 and tap "Calculate."

The system will automatically calculate all the coordinates for each equal point along the line.

💾 Step 4: Save the Points

Once the calculation is done, tap "Save."
A pop-up window called "Point Info" will appear.
Here, give your points a name — for example, D1 — and tap "OK."

📍 Step 5: View the Points in Stakeout

Now, go back to the Survey interface and tap "Point Stakeout."
You'll see that all your equal-distance stakeout points have already been saved automatically in the Point Coordinate list.

From here, you can start your stakeout work directly — no manual calculation needed!

✅ Final Thoughts

And that's it!
You've just completed an equal distance stakeout with your RTK — quick, easy, and accurate.

This feature is especially useful for road layout, pipeline construction, or any project that requires precise equal spacing between points.
Give it a try next time you're out in the field!
