로코 포지셔닝 노드(Loco Positioning Node)는 Loco Positioning 시스템에서 Anchor(앵커) 또는 Tag(태그)로 실행할 수 있는 다목적 포지셔닝 장치입니다. 시스템은 노드와 태그 사이의 거리를 측정하며, 이러한 거리로부터 태그를 운반하는 개체의 절대 위치를 계산할 수 있습니다.
사양은 표준 2-way 범위 모드를 기반으로 합니다.
Features
- Supports Anchor, Tag or Sniffer mode
- Can be used as a standalone system with some Nodes acting as Anchors and one or more nodes acting as Tags
- Multiple powering options
- On board MCU
