Smooth Your GPS Coordinates — Cleaner Recorded Routes

If you have ever looked at a recorded ski run and noticed jagged, zigzag lines where you know you skied a smooth arc, you have experienced GPS jitter. It is a common problem — and we built a feature specifically to fix it.

What Causes GPS Jitter?

GPS signals bounce off mountain walls, get scattered by dense tree cover, and lose accuracy in steep valleys. Your phone might report your position a few metres off to the left, then a few metres to the right, creating a noisy track even when you were carving a clean line. High-speed skiing amplifies the visual effect because each errant point is farther from the next.

How Coordinate Smoothing Works

The Bonvo.Ski app applies an intelligent smoothing algorithm to your recorded GPS coordinates. Instead of plotting every raw data point, the app analyses the trajectory and removes statistical outliers while preserving the true shape of your path. The result is a route that looks the way your run actually felt — fluid turns, clean traverses, and accurate descents.

When to Use It

Coordinate smoothing is especially valuable in these situations:

• Tree-lined runs — Heavy canopy cover degrades GPS accuracy significantly.
• Narrow valleys — Steep rock faces on both sides reduce the number of visible satellites.
• High-speed descents — Small errors become large visual artefacts at speed.

Check your recorded runs in the app and see the difference. Cleaner tracks mean better stats, more accurate elevation profiles, and recordings you are genuinely proud to share with your ski group.
