Current Projects A - C
Over the past decade GPS satellite technologies have been widely tested in Europe to be used for the train localization. Combined with satellite communications and terrestrial communication techniques, an economical train control system solution can be realized. Within the scope of this project, a new satellite-based system as an evolution of the ERTMS-ETCS platform for automatic train control and management will be developed and validated. With such a train control system, the overall system cost can be significantly reduced.
ABSOLUTE - Aerial Base Stations with Opportunistic Links for Unexpected &Temporary Events
Recent events have shown that in the aftermath of an emergency, disaster or any related tremendous unexpected events, a reliable communication infrastructure plays an important role in providing critical services including emergency recovery operations, critical infrastructure restoration, post-disaster surveillance etc. In most of the cases, immediately after a large scale disaster, the normal terrestrial network infrastructure is seriously compromised and cannot guarantee reliable and large scale coverage for rescue teams and citizens. Current mission critical communication systems including PPDR (Public Protection for Disaster Relief) systems are heavily limited in terms of network capacity and coverage. They are not designed for or suitable to address large scale emergency communication deployments immediately after the disaster scenarios where these networks can provide dependable and resilient network connectivity at higher data rates over large coverage areas. Moreover, PPDR systems are limited by interoperability barriers and the technological gap with commercial technologies and evolving standards.
Aeronautical Satellite Communications Channel Characteristics
The wireless signal propagation characteristics from a satellite based transmitter to an airborne receiver are of special interest for air traffic management as well as for passenger communications. Especially applications incorporating safety-of-life features require not only an average reliability of the transmission link but rather a high availability and have stringent requirements on the continuity-of-service.
The Project „advanced DVB-RCS“ is aiming at the development of a testbed of an advanced DVB-RCS modem with new coding for forward error correction and with adaptive coding and modulation in the reverse channel. DLR develops and implements the resource management algorithms for DVB-RCS (MAC-Layer) and the algorithms for the encapsulation of the IP datagrams.
Advanced forecast for ensuring communications through space (AFFECTS). Severe space weather effects may degrade the performance of modern telecommunication and Global Navigation Satellite Systems (GNSS). Therefore, solar storms are able to affect our modern infrastructure facilities and installations. As a result, restricted functionality or catastrophic failure of telecommunication and navigational systems could lead to serious economic losses, safety risks or to the restriction of the quality of live.
Alert 4 All (A4A)
The Alert4All Project, coordinated by DLR, is a EU-funded collaborative project in the frame of the 3rd REA Security Call that develops an advanced concept for alert and communications towards the population in crisis situations from a European perspective.
ARIEL – Air Traffic Resilience
Civil aviation is an important asset of today’s mobile society and belongs to the critical infrastructures. Thus, the protection of civil aviation is of high importance to society. In aviation, economic pressure requests cost reductions and improved efficiency in handling aircraft. As a consequence, the infrastructure and technical systems become more and more interconnected to save costs through re-use of resources and exploitation of synergies. Besides these desired effects, the interconnection of formerly separate technical systems generates new risks. These risks are especially caused by threats from cyberspace. Main goal of the project ARIEL is to perform a holistic risk analysis and evaluation of critical infrastructures in aviation, since these might become the target of sophisticated cyberattacks to create new threats to public safety and security.
ArtemEx: Artemis Experiment for Optical Feeder Links
ArtemEx is an ESA project (Artes 5.2) involving Cassidian Optronics and DLR to verify an advanced transmission concept for ground-to-space optical links.
Automated Aids for safe and efficient Vessel Traffic Processes (A++Set)
Leading principle during navigation of vessels is the avoidance of collision and groundings to protect life, goods, and the maritime living space. However, a virtually unchanged number of ships’ accident has been observed during the last decade. Statistical analyses show that more than 50% of ship collisions have navigational causes, whereby 65% of whom has been induced by human factor. Main reasons in this context are insufficient situation monitoring (28%), misleading evaluation of ships’ motion (17%) as well as fatigue and overstressing of nautical staff (13%). The risk on incorrect decisions and therewith the risk on accidents can be reduced by application of automated assistance functions supporting the seafarer in situation monitoring, evaluation, and decision finding.
BATS - Broadband Access via integrated Terrestrial & Satellite systems
The research project BATS (Broadband Access via integrated Terrestrial & Satellite systems), funded under the European Union 7th Framework Programme, addresses the delivery of BroadBand (BB) future services in Europe according to the EC Digital Agenda objective to reliable deliver >30Mbps to 100% of European households by 2020.
