Foundations Laid for Building-Scale GPS Technology


In the BMBF-funded project, Chemnitz University of Technology has developed a unique microchip that can determine the most precise location within buildings

Modern mobile navigation is hardly conceivable without the use of satellite-based GPS. Similar solutions that allow for orientation within a small space, for example inside of large, winding buildings, are currently very scarce.

They aim to revolutionise mobile navigation within confined spaces. Pictured from left: Daniel Froß, Marko Rößler and Marcel Putsche.

The reason for this: the technological basis for ultra-precise position determination at a micro level is currently missing – until now.

A research team from the Chair of Circuit and System Design at Chemnitz University of Technology has succeeded in developing the first highly efficient localisation chip that combines both the lowest possible energy consumption and very high localisation accuracy.

The joint project “FIND-IT – Competence Platform for Indoor Positioning and Logistics” was funded by the Federal Ministry of Education and Research (BMBF) over a three-year span from 2016 to 2019, to the tune of 1.2 million euros.

In addition to Chemnitz University of Technology, project and application partners on the project include Infineon, the SIMATIC RTLS division from Siemens and SIGMA Chemnitz.

Everything started with the algorithm

Towards the beginning of the development of a functioning prototype, there was the question of a suitable algorithm: “The algorithm helps us determine the exact position of an object in the room,” explains project manager Marko Rößler.

It took around a year of programming by the team to produce the first working version of the algorithm. This was preceded by numerous test-runs in the virtual environment.

After this initial development phase, the team was ready to integrate the algorithm into a microchip. Here, the algorithm itself only functions as an illustration of the functional principle behind the hardware, but this is required for the actual deployment of the technology.

The particular challenge for the team as it transferred software into hardware was that the hardware could not be changed after the fact. “So, we needed to be sure that we didn’t miss anything, in order for the localisation to work later on,” says Rößler.

The advance validation of the location played a special role in this process. For this, the team again completed many test-runs in a virtual setting.

The final step in the development of this new technology was the integration of the finished chip into a prototype. That means the development of mobile hardware that can act as a placeholder for the marketable device.

Following this, the team will be preparing the chip for market readiness as well as full entry into the market.

Im Focus: Freiburg researcher investigate the origins of surface texture

Most natural and artificial surfaces are rough: metals and even glasses that appear smooth to the naked eye can look like jagged mountain ranges under the microscope. There is currently no uniform theory about the origin of this roughness despite it being observed on all scales, from the atomic to the tectonic. Scientists suspect that the rough surface is formed by irreversible plastic deformation that occurs in many processes of mechanical machining of components such as milling.

Prof. Dr. Lars Pastewka from the Simulation group at the Department of Microsystems Engineering at the University of Freiburg and his team have simulated such...

Im Focus: Making the internet more energy efficient through systemic optimization

Researchers at Chalmers University of Technology, Sweden, recently completed a 5-year research project looking at how to make fibre optic communications systems more energy efficient. Among their proposals are smart, error-correcting data chip circuits, which they refined to be 10 times less energy consumptive. The project has yielded several scientific articles, in publications including Nature Communications.

Streaming films and music, scrolling through social media, and using cloud-based storage services are everyday activities now.

Im Focus: New synthesis methods enhance 3D chemical space for drug discovery

After helping develop a new approach for organic synthesis -- carbon-hydrogen functionalization -- scientists at Emory University are now showing how this approach may apply to drug discovery. Nature Catalysis published their most recent work -- a streamlined process for making a three-dimensional scaffold of keen interest to the pharmaceutical industry.

"Our tools open up whole new chemical space for potential drug targets," says Huw Davies, Emory professor of organic chemistry and senior author of the paper.
