Supplier / Manufacturer Overview

GridRTLS supplies fusion positioning terminals designed to bridge
indoor UWB positioning and outdoor GNSS-based location into a continuous, usable data stream.
This category focuses on where and how positioning data is fused and output,
not on anchor deployment or platform logic.

FOCUS AREA

In hybrid indoor–outdoor projects, the challenge is rarely sensor availability,
but how positioning sources are combined and delivered in a predictable way.
Fusion terminals act as the boundary device between positioning sources
(UWB, GNSS, inertial inputs) and the customer’s platform.

The goal is not “perfect fusion”, but stable handover, clear data ownership,
and well-defined output behavior so downstream systems can make reliable decisions.

WHO WE WORK WITH

We primarily work with system integrators and engineering teams
building hybrid positioning systems across factories, yards, tunnels, ports,
and large infrastructure sites where indoor and outdoor positioning must coexist.

FUSION TERMINAL ROLE IN THE SYSTEM

  • Aggregate positioning inputs from UWB anchors and GNSS modules.
  • Manage indoor–outdoor transition logic at a defined system boundary.
  • Output normalized positioning data or events to the customer platform.
  • Keep fusion behavior stable while allowing platform-level customization.

If your project requires continuous positioning across indoor and outdoor zones,
this page is intended to help you define fusion responsibility, data outputs,
and RFQ inputs, and move toward an RFQ-ready fusion terminal configuration.

Capability highlights

Clear fusion boundary definition

Fusion behavior is defined at the terminal level, avoiding ambiguity between device, gateway, and platform responsibilities.

Indoor–outdoor transition handling

Designed to support predictable handover between UWB and GNSS zones rather than continuous re-calculation.

Platform-agnostic data output

Outputs are structured for third-party RTLS or location platforms without locking customers into a specific stack.

Stable multi-source input handling

Supports simultaneous UWB and GNSS inputs without unstable switching behavior.

Deployment consistency across zones

Configuration remains consistent across multiple terminals in large sites.

Selection criteria (what to specify in an RFQ)

1 Fusion responsibility
⌄

Specify whether the terminal outputs raw sources, fused position, or normalized events.

2 Indoor–outdoor boundary definition
⌄

Define how and where transitions occur (zones, triggers, confidence thresholds).

3 Expected output format
⌄

Coordinate system, timestamps, update rate, and event definitions.

4 Latency tolerance
⌄

Acceptable delay during handover impacts fusion strategy and buffering.

5 Integration interface
⌄

Protocol, data schema, and downstream platform expectations.

6 Environmental constraints
⌄

Indoor/outdoor placement, temperature range, vibration, enclosure requirements.

7 Scaling model
⌄

Number of terminals and how configuration is replicated across deployments.

Customization / OEM / ODM

For fusion positioning terminals, customization usually focuses on
data behavior and interface alignment rather than physical form.
We recommend fixing fusion responsibility early and keeping customization
limited to parameters that do not affect system stability.

OEM/ODM scope may include interface definitions, output filtering,
enclosure adjustments, and controlled firmware parameters.
Deep fusion-logic changes should be confirmed early, as they directly affect
system validation and long-term maintainability.

Integration & architecture

Wired PoE / Ethernet Cellular 4G/5G Backhaul Indoor–Outdoor Fusion (UWB + GNSS/RTK)

Fusion positioning terminals should be treated as system boundary components.
They define where sensor data becomes positioning output, but do not replace
the customer’s platform logic.

  • Confirm whether your platform expects fused positions or source-level data.
  • Define indoor–outdoor transition behavior before deployment.
  • Align timestamp and coordinate system handling across sources.
  • Keep fusion logic stable across pilot and rollout phases.
Supplier proof

Factory, delivery discipline & real deployments

Evidence that matters to SI teams: how we lock BOMs, keep batch consistency, and ship integration-ready hardware.

Config-first quoting
Align output level + site constraints before locking BOM to prevent re-quoting.
Batch consistency
Configuration and revision control across pilot → rollout to reduce maintenance risk.
Integration-ready delivery
Clear integration notes and commissioning expectations—no “mystery behavior” in the field.
QA & traceability
Pre-shipment verification + traceability mindset for multi-batch projects.
Read full supplier proof ⌄
Fusion responsibility defined before delivery
Fusion behavior and output expectations are aligned before shipment.
This avoids late-stage changes that could break platform integration.

Consistent behavior across terminals
Multi-terminal deployments maintain consistent fusion and output behavior,
reducing validation effort during expansion.

Scope boundaries
  • We provide fusion terminal hardware and documentation.
  • We do not operate positioning platforms or define business logic.
Scope boundaries (important)
  • Hardware + integration-ready documentation supplied; no on-site cabling / civil construction.
  • No turnkey RTLS platform operation for end customers; platform & site delivery handled by SI / partners.

Operating environment

Indoor/outdoor installation and temperature range confirmation.

EMC / industrial compliance

Designed for industrial electromagnetic environments.

Time synchronization tolerance

Acceptable clock drift and alignment limits defined per project.

Warranty & RMA policy

Batch traceability supports efficient replacement.

  • Input signal verification for UWB and GNSS sources

FAQ

What does a fusion positioning terminal actually do? ⌄

It defines how multiple positioning sources are combined and delivered, without owning platform logic.

Does the terminal calculate final positions? ⌄

It can output fused data or normalized events, depending on project definition.

Where should fusion logic live: terminal or platform? ⌄

The terminal handles boundary-level fusion; platform handles business logic.

How is indoor–outdoor handover managed? ⌄

Based on predefined triggers and confidence thresholds agreed at RFQ stage.

Is RTK required for all projects? ⌄

No. GNSS/RTK is used when outdoor accuracy and continuity require it.

How does fusion affect latency? ⌄

Fusion adds minimal latency when properly configured; acceptable limits should be defined early.

Can fusion terminals work with third-party platforms? ⌄

Yes. Interfaces are designed for platform-agnostic integration.

How do you ensure consistent behavior across multiple terminals? ⌄

Configuration presets and batch control keep fusion logic consistent.
