Without GPS, position holding is provided by the VPS sensors.
VPS needs a good lighting and a recognisable pattern or texture to work properly.
If the lighting isn't good enough or the floor surface doesn't have a good pattern, you will see some drifting.
Here's what the specs suggest:
Vertical: ±0.1 m (with VPS), ±0.5 m (with GPS Positioning)
Horizontal: ±0.3 m (with VPS), ±1.5 m (with GPS Positioning)
3-5 cm is well within specs, so is normal. |
