Brain Training for your Navigation System!

09.02.2009
Fraunhofer FIRST presents a new generation of navigation systems

With its Future Mobile Navigation Toolkit, Fraunhofer FIRST shows from February 16th until 19th 2009 components for a new generation of navigation devices at GSMA Barcelona (booth G-49, hall 1).

In future, these will supply you with seamless, up-to-date information, provide reliable forecasts and feature a number of additional technologies such as improved search and compression algorithms.

Would your navigation device pass an IQ test? Is it familiar with every detail of the route? Can it tell the future? Can it come up with the correct route in a matter of seconds? Is it your constant reliable companion both indoors and out? Or is its memory rather patchy and are its reactions a bit on the slow side? Does it leave you in the lurch whenever you enter a building? Then you should prescribe it a dose of brain training!

· TPEG Service Centre
To transmit traffic information, FIRST uses the TPEG (Transport Protocol Expert Group) broadcasting standard. Existing navigation devices receive traffic information on congestion and roadworks via the Traffic Message Channel (TMC). But this system is patchy, being confined to 35,000 points across Germany. Another draw-back is the limited transmission capacity of the analogue radio signal. While TMC enabled some 10 to 20 messages per minute to be broadcast via analogue FM radio, TPEG allows the transmission of approx. 3,000 messages per minute. And there's another difference: when broadcasting via TMC, a maximum of 300 messages can be fed into the system at any one time, while with TPEG there are no limits. This makes it possible to provide comprehensive, up-to-date information on the traffic situation. Fraunhofer FIRST has its own TPEG Service Centre, where traffic data from various sources is received, decoded and checked for its traffic relevance. Relevant data is sampled to TPEG services and digitally broadcast via a transmitter. To implement the TPEG services, FIRST is developing Java-based components in accordance with CEN ISO/ TS 18234.
· Prognostic Routing
For prognostic routing, Fraunhofer FIRST uses external traffic simulations. The prognoses are taken into account in planning the route and ensure smooth navigation to the destination. The routing algorithms are based on a multilevel concept and are implemented in Java or C++ on different mobile clients. Main memory requirements for the routing data for the whole of Europe are between six and 20 MB.
· Map Compression
FIRST offers its own technologies for processing geodata (NAVTEQ, Tele Atlas), which allow a customized rendering of maps on the client, the data for both the routing and the visualization being optimized. Efficient compression algorithms reduce the data for the whole of Europe to two GB, at the same time ensuring high map quality. An inspection tool developed by FIRST checks that the data that is output on the client matches the original data.
· Search
The toolkit is complemented by efficient search algorithms, which make it possible to rapidly reduce the size of the search space and are thus able to output search results a great deal faster than conventional devices. A special feature here is the fact that the methods are not based on a hierarchical search using structured search paths (country, city, street or POIs). Instead, they can search simultaneously in a large number of possible datasets and even process incomplete queries.
· Seamless Navigation
In future, FIRST's navigation toolkit will be extended by components allowing seamless indoor/ outdoor navigation or seamless navigation between different means of transport. These include the use of Differential GPS (DGPS) and Galileo data as well as sensor fusion technologies. Fraunhofer FIRST has its own DGPS test bed, where server applications with a precision of less than a metre can be developed and the seamless integration of different receiving devices can be tested. In addition, a Galileo Lab is currently being installed at FIRST that will enable interested customers to test the new standard.
· Standardization
The TPEG Toolkit is described by a collection of ISO/ TS Standards covering initial applications and is now under continuous develop-ment by the Traveller Information Services Association (TISA), a non-profit organization comprising over 90 commercial and public service/ authority members. Already many TPEG applications, such as Road Traffic Messages, Traffic Event Compact and Public Transport Information are standardized through ISO/CEN and can be delivered to end-user devices with DAB or other transparent bearer capability feeding a TPEG decoder for the appropriate application(s). Fraunhofer FIRST is a member of the TISA TPEG Applications Working Group (TAWG).

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
