Build Submaps for Indoor Positioning | Marvelmind
What This Video Covers
This demo shows how to build a map consisting of multiple submaps for your indoor positioning system. The process involves allocating beacons strategically to individual submaps, freezing each submap independently, then semi-manually positioning and aligning them on the main map to minimize mobile beacon handover jumps during transitions. Proper submap configuration ensures continuous, seamless indoor tracking across large warehouse and facility spaces.

Key Takeaways
- Allocate each beacon to exactly one submap; beacons cannot be shared across multiple submaps
- Ensure every submap contains sufficient beacons to maintain independent positioning capability and prevent map freeze-ups
- Freeze individual submaps first, then position and align them on the main map before final freeze
- Semi-manually position submaps to minimize handover jumps when mobile beacons transition between regions
- Proper submap architecture is critical for reliable indoor location tracking in large warehouse and facility environments
- This approach supports autonomous robot navigation, forklift tracking, and warehouse automation systems across extended areas
Who Should Watch This
System integrators, warehouse automation engineers, and robotics professionals implementing multi-area indoor positioning systems. This guide solves the critical challenge of extending positioning coverage across large facilities by properly segmenting and aligning beacon networks without positioning gaps or handover jumps.
FAQ
Detailed Overview
Building an effective indoor positioning system for large facilities requires intelligent use of submaps. This technical demo walks through the three-stage process of constructing multi-submap layouts that maintain continuous RTLS coverage without positioning discontinuities. Stage one focuses on strategic beacon allocation—ensuring each beacon belongs to exactly one submap while guaranteeing every submap contains sufficient beacons for standalone operation. Stage two involves independently freezing each submap to lock their internal beacon geometries. Stage three is the critical alignment phase where submaps are positioned semi-manually on the master map and fine-tuned to minimize handover jumps when mobile beacons transition between regions. This methodology is essential for warehouse automation, autonomous indoor robot navigation, and forklift tracking applications spanning multiple work zones. Proper submap construction prevents mapping freeze-ups and ensures reliable indoor location tracking throughout your facility's operational areas.
