Reverse RFID PositioningNo initialization. No drift.
Doesn’t require dedicated operator
Horizontal accuracies to a few feet easily achieved.
Low maintenance, low cost, zero power infrastructure.
Built on global standard technology and commercially available

TIMMSData acquisition and map updating conducted as a service
• 2D Floorplans
• 3D Models
• Custom deliverables as requested
Data is web enabled, in secure cloud environment
• Data can be delivered on dedicated client servers as well for enhanced security
All data is geo-referenced
• Every point has a Lat/Lon/Alt associated with it.
