Description
Fixed UWB Device Providing Positioning Reference
SpaceAnchor-A1 is a fixed anchor device that serves as the core of the GrowSpace UWB system. It is installed at fixed positions in indoor spaces and measures real-time distance to tag devices. Using these distances, the system calculates each tag’s precise location via trilateration. The anchor plays a central role in ensuring location accuracy.
✅ Key Features
🔌 Easy USB power installation
📡 Supports 4 or more anchors simultaneously
🏗️ Can be mounted on walls, ceilings, and other indoor surfaces
📏 TWR-based trilateration for accurate 2D/3D positioning
📏 Deployment Guidelines
Positioning Method
TWR-based Trilateration
Anchors Required
3+ for 2D · 4+ for 3D positioning
Recommended Spacing
15–20 m between anchors
Minimum Anchor Distance
2 m or more
🏗️ Installation Tips for Best Accuracy
📈 Mix Installation Heights
Placing anchors at varied heights (e.g. ceiling + floor/column) sharpens Z-axis (height) accuracy — anchors all at one height struggle to resolve vertical position.
🛡️ Avoid Metal & Glass
Highly reflective surfaces can cause multipath interference. Drywall and concrete walls are preferred mounting surfaces.
✋ Add Redundancy
In larger spaces, adding 1–2 extra anchors keeps the system running smoothly even if one anchor goes offline.
🧪 Use Cases
🚶 Worker movement analysis
📍 Asset location tracking
🏭 Production line monitoring
📌 From a 3-anchor pilot to a full production floor, SpaceAnchor-A1 scales with your deployment — each anchor snaps into the same trilateration-based RTLS pipeline, so adding coverage is as simple as adding more anchors.
