Azure Spatial Anchors (ASA) Alternative & Migration Hub - Fast, private, scan‑agnostic migration to MultiSet VPS

Move to a future‑proof, enterprise VPS with sub‑10 cm precision, on‑prem  options, and cross‑platform SDKs (Unity, iOS, Android, WebXR, Quest).

Why Replace ASA with MultiSet

Accuracy & stability: Median sub‑10 cm alignment indoors/outdoors; low drift in dynamic environments.
Privacy & control: Self‑host on‑prem, private cloud, or use our cloud; full data ownership.
Scan‑agnostic mapping: Bring E57, Matterport, NavVis, Leica LiDAR, CAD/BIM, or scan with our iOS app.
Cross‑platform: Unity/AR Foundation, native iOS (ARKit), Android (ARCore), WebXR (Three.js/Babylon), Meta Quest (OpenXR via Unity).
Scale: Multi‑floor, campus‑scale mapping with seamless map‑to‑map transitions.
Fast time‑to‑value: Developer‑friendly SDKs, sample scenes, and a guided migration checklist.

ASA → MultiSet
migration at a glance

Replace ASA SDK calls with MultiSet SDK calls and swap anchor creation/localization to map‑based visual localization.
What stays: Your app logic, UI, content pipeline, and most AR Foundation components.
Choose a map source
Import existing scans (E57/Matterport/NavVis/Leica) or scan with MultiSet iOS.
Create a Map Set
Import existing scans (E57/Matterport/NavVis/Leica) or scan with MultiSet iOS.
Initialize SDK
Unity/iOS/Android/WebXR; configure endpoint (cloud or on‑prem) and auth.

Frequently asked questions
What is a Visual Positioning System (VPS) and why do enterprises need it?

A VPS gives devices precise 6-DoF position and orientation in the real world so AR content and robots can align to physical assets exactly indoors, outdoors, and at scale. Compared with GPS, Wi‐Fi, beacons or QR codes, VPS provides far higher accuracy and persistent spatial awareness, which is essential for navigation, training, inspection, and digital‐twin overlays in complex facilities. VPs also provide multiplayer environments which provide a shared sense of space for a fleet of devices.

How do I integrate MultiSet AI's VPS into my applications?

Integrate MultiSet AI's VPS using our REST API, Unity SDK, or native SDKs for iOS and Android. This ensures seamless integration and precise localization in your AR projects. Our platform also supports on‐premises deployments and offline SDKs, keeping your data secure. Designed for various environments, our VPS technology handles everything from small rooms to large stadiums.

How does MultiSet AI's VPS handle different lighting conditions and environmental changes?

MultiSet AI’s neural networks are trained for diverse lighting conditions and dynamic environments. The VPS remains robust and accurate under typical lighting variations, minor physical changes, and the presence of people, ensuring reliable performance. Ideal for manufacturing, warehouse training, and other industrial settings, our VPS technology delivers centimeter‐level accuracy even in challenging environments.

How fast can we go from pilot to campus-wide coverage?

Teams typically stand up a first localized scene in minutes using samples, then expand by stitching scans into map sets for seamless indoor↔outdoor and multi-building continuity. This lets you scale predictably while keeping performance consistent across sites.

What is a visual positioning system (VPS) and how does MultiSet differ?

A visual positioning system uses camera imagery to calculate a device’s 6‐DoF pose. MultiSet’s VPS is scan‐agnostic. It fuses LiDAR data, point clouds and 3D scans, delivers sub‐centimetre accuracy, and scales to 100,000+ m2 venues without markers or beacons.

What hardware do I need to use MultiSet VPS?

Any modern phone, tablet, AR headset, robot or drone equipped with a standard RGB camera. Devices with LiDAR (iPhone Pro, iPad Pro, Quest 3) gain extra accuracy but are not required.
