Maritime traffic engineering
The maritime traffic system is an essential basis for the economic development, competitiveness, and prosperity for Germany as well as Europe. The world seaborne trade continued to grow in 2011 with 4% and achieved a total transport volume of goods in the order of 8.7 billion tons.
To meet the challenges of future Air-Traffic Management (ATM), aeronautical communication and navigation technologies are currently modernized. In communications, the air-ground communications standard LDACS (L-band Digital Aeronautical Communications System) is under development. The main goal of the DLR internal project LDACS-NAV (LDACS Navigation) is to advance the LDACS technology candidate LDACS1 to include navigation functionality. The feasibility of this approach is proved by in-flight measurements.
LOCL: Lunar Optical Communications Link
In September 2013, NASA’s Lunar Atmosphere and Dust Environment (LADEE) spacecraft was launched with the main scope of collecting information about the lunar atmosphere. The spacecraft also hosts the Lunar Laser Communications Demonstration (LLCD), which has successfully demonstrated bidirectional communications based on 1550 nm laser technology and PPM Modulation.
MONALISA 2.0 aims at contributing to a continuous improvement and development of efficient, safe and environmentally friendly maritime transport in the European Union by implementation of a series of measures in accordance with the EU's transport policies.
MONitoring of the Ionosphere by innovative Techniques, coordinated Observations and Resources. The main goal of MONITOR is to design, develop, deploy and operate a system for collection, processing and archiving of ionospheric observation data.
Multi-Scale Ionosphere Model from Combination of Modern Satellite observation Techniques. The MuSIK project aims at developing methods for imaging the three-dimensional electron distribution of the ionosphere/plasmasphere systems.
NEXT-OBP-GEOSat (NEXT On-Board Processing Unit für GEOSatelliten)
Durch eine Netzcodierung an Bord eines Satelliten (in einer On-Board Processing Unit) erweitert sich das Spektrum der Anwendungsmöglichkeiten der Netzcodierung für die Satellitenkommunikation erheblich. Im Projekt NEXT-OBP-GEOSat soll eine Nutzlast für einen Kommunikationssatelliten entwickelt werden, mit der neben dem „Network Coding“ zwei weitere Kommunikationsexperimente durchgeführt werden können.
NGOBP - Next Generation Regenerative On-Board Processor in Broadband Satellite Systems for Security Applications
The purpose of the activity is to study, develop and validate the OPB functionalities for the next generation of satellite OBP hosted payloads for high speed security applications and institutional purposes. The scope of the activity also includes a comparison between the OBP solution and the conventional transparent system in terms of cost, technical and operational point-of-view to allow for benchmarking. On-board switching will be combined with new network coding concepts to save power and bandwidth in the satellite downlink. The activity is accomplished by building a demonstrator implementing a complete end-to-end system.
PHAROS – Project on a Multi-Hazard Open Platform for Satellite Based Downstream Services
The PHAROS project (Project on a Multi-Hazard Open Platform for Satellite Based Downstream Services) aims at designing and implementing an innovative multi-hazard service platform which integrates space-based observation, satellite communications and navigation assets to provide sustainable pre-operational services for a wide variety of users in multi-application domains, such as early detection of risks and emergencies, environmental monitoring, risk and crisis management and population alerting. Potential users of the PHAROS platform are both institutional users, such as authorities and crisis managers (primary users) and non-institutional users, such as insurance companies and research groups (secondary users).
Precise and integer Localisation and Navigation in Rail and Inlandwater Traffic. Mobility of people and transport of goods are important for a smoothly functioned society. These also significantly affect the quality of living and the competiveness of the economic system. Railway and inland water transportation become more important particularly with regard to current ecological and economical matters.
Processing Russian and European EARTH observations for earthQUAKE precursors Studies (PRE-EARTHQUAKES) A large scientific documentation is to-date available about the appearance of anomalous space-time patterns of geophysical parameters measured from days to week before earthquakes occurrence.
PrOSIRIS – Pre-Operational Optical Space Infrared Downlink System
Mit den steigenden Sensorkapazitäten von modernen Erdbeobachtungssatelliten wächst der Bedarf an Datenübertragungssystemen, welche eine hohe Datenrate zur Verfügung stellen können. Insbesondere bei Kleinsatelliten („BIRD-Klasse“, ca. 50x50x50cm) hat die Kombination aus hoher Datenübertragungsrate, geringem Gewicht, niedrigem Leistungsverbrauch und kleinem Formfaktor höchste Priorität. Hierzu bieten sich miniaturisierte Laser-Sendeterminals für direkte optische Downlinks an, welche mit Antennendurchmessern von wenigen Zentimetern sehr kleine und leichte Bauformen aufweisen. Zudem unterliegt diese Übertragungstechnologie keinerlei Frequenzvergaberestriktionen.
The German Aerospace Center (DLR) is developing a Railway Collision Avoidance System (RCAS), a 'safety overlay' system which can be deployed on top of any existing safety infrastructure in train networks.
The main objective of this activity is to design and develop a software based validation platform implementing and fully validating key functions of the DVB-RCS Next-Generation Standard.
