This is why the IPS market has not taken off and also why tt2 stands out.

The current IPS market consists of solutions that may showcase sufficient performance, but require costly and time consuming installations of external hardware (e.g., UWB, iBeacons, Wi-Fi triangulation).

The GPS and other satellite-based positioning systems commonly used for outdoor positioning (as in Google or Apple maps), require satellite signals reaching the user’s device. When indoors, these signals typically weaken to the point where they fail to position the user sufficiently. This is where indoor positioning systems (IPSs) can create value.

Welcome to the simple and affordable future of indoor positioning.

Unlike other IPS providers tt2’s AI-powered IPS runs independently from any external signals. All you need is our SDK, a map, and a device with a gyroscope and an accelerometer (as most mobile devices have). No external hardware, no venue-specific tuning, no hassle.

tt2’s indoor positioning runs completely isolated from external signals and only relies on the device’s sensor data, allowing tt2 to take positioning where the GPS can’t. Everything that is done with outside positioning today – spatial analytics, location-based messaging, and real-time navigation – is made possible indoors with tt2.

Why tt2


tt2 Software is unique and scalable

The tt2 software, designed for simple and intuitive integration, can be installed on mobile phones and existing mobile computers as long as they have an accelerometer and gyroscope.

From GPS to tt2 

Let tt2 take over when the GPS loses signal, creating a seamless positioning experience for the user.

Once the user enters the metro station, GPS signals are lost, and the blue dot is stuck at the latest known position.
The tt2 positioning, however, is independent from all external signals and continues to position the user in the metro station deep underground.

Once the user steps inside, or going underground and the device loses GPS signal, tt2 can seamlessly take over using the last GPS position as starting point.

System Overview


General Overview

The tt2 system is a relative positioning system, meaning it requires a start location and device direction. The system can be started in multiple ways. Usually this is done using a fixed-point reference, such as a QR-code or a cradle storage location. Other possibilities are to start the system via external sources such as Wi-Fi-signals or GPS-signals to obtain a location estimate, together with a magnetometer compass reading to determine device direction.

The system requires that the device is equipped with an Inertial Measurement Unit (like most modern devices). It can be deployed at any venue without setting up any infrastructure or doing venue-specific tuning. Together with our map-generation tool, a venue can be configured in minimal time. The only requirement to set up a new venue is to provide the tt2 system with a floorplan. 

The tt2 system is a revolutionary positioning system for mobile devices, independent of external signals.

Indoor positioning has never been so simple – Get started in 3 steps

We can host the servers, or we can share a Docker image if you choose to host them yourself. Either way, we will help you with the set-up to make it as quick and easy as possible.

The tt2 SDK has been designed for simple and intuitive use to make it easily integrated into your iOS or Android application. See code examples om our tt2 SDK documentation page to speed up your development. Of course we can help you through 1-on-1 consulting as well.

tt2 needs to know where it will deliver its position to. Use our map generator, MapGen, to generate a digital representation of your venue from a simple floor plan image. Place barcodes and information in your venue to track interactions. We’ll help you get started with the tools.
