ABSOLUTE
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. In order to test and validate new developed receiver algorithms, software based implementations are used which allow a faster time to market. Therefore, channel models designed to simulate propagation characteristics of the satellite-to-aircraft channel need to address all aspects of propagation impairments.

BATS
BATS addressed the integrated delivery of BroadBand (BB) future Internet services for European coverage according to the EC Digital Agenda objective to reliably deliver >30Mbps to 100% of European households by 2020. In order to accommodate the ‘unserved’ and ‘underserved’ areas of Europe, an ultra-high speed satellite system has been researched that provided order of magnitude cost/bit reductions and solutions to existing market barriers of bandwidth and latency limitations. The project was built on Terabit/s satellite studies conducted by European Space Agency and extended them into an overall network and service delivery concept. A novel architecture has been proposed which combines satellite and terrestrial service delivery via an Intelligent User Gateway (IUG), dynamically routing each traffic flow according to its service needs through the most appropriate delivery mechanism to optimize the Quality of Experience (QoE). The integration complied with emerging home network environment standards and provided resilience and reliability of service provision to the users by bonding diverse access networks. To cope with such scenario, BATS also provided a unified network management framework.

DODfast (Demonstration of Optical Data link fast)
The institute was responsible for the communications link design, experiment design and optimization of the ground station. The DLR spin-off Vialight Communications GmbH built the airborne terminal. New opto-mechanical tracking systems were developed and applied on flight and ground segment for link acquisition and stabilization. The flight tests were carried out at the end of November 2013 near the Airbus Defence & Space location in Manching, Germany. The campaign successfully demonstrated the maturity and readiness of laser communication for aircraft downlinks at a data rate of 1.25 Gbit/s. Performance could be measured at aircraft speeds up to Mach 0.7 and video data from an onboard camera was transmitted. Tracking accuracies of up to 20 rad rms for the airborne terminal and the ground station were achieved at instantaneous tracking errors below 60 rad and 40 rad, respectively. The tracking link worked up to a horizontal distance of 79 km and data transmission was possible up to 50 km. The experiment shows the maturity of aeronautical laser communications in a very challenging environment. Future aircraft may be equipped with that technology for the sake of passenger connectivity and payload data transmission, for example. With this optical data link, high resolution images recorded by a camera during surveillance flights are transmitted to the Transportable Optical Ground Station (TOGS) of the German Aerospace Center (DLR).

FEC4Space
The project is dealing with the design and with an approach to a standardisation of new forward error correction codes for optical near-earth and deep-space data links as well as for RF deep-space data links. The new forward error correction mechanisms, which are based on LDPC codes, promise both an enhanced error correction capability and low complexity. This improved performance enables higher data rates or alternatively a saving of transmitter power with comparably low effort. Especially for space communication saving of transmitter power is a very important aspect, because this influences positively the design of the whole spacecraft or satellite (e.g. smaller solar panels, less volume and mass, smaller RF amplifiers, smaller radiators for cooling).

GeReLEO
Low-Earth-orbit (LEO) satellites require both data links for telemetry, tracking and command (TT&C) and for download of mission data (e.g., Earth observation). A single ground station can maintain a contact to a passing LEO satellite for relatively short time only (typically ~10 min), and together with high-resolution sensor systems onboard the satellites producing high amounts of data this leads to a serious bottleneck. In fact, depending on the actual orbit parameters (altitude and inclination) the long-term average visibility as seen from one ground station is only 1% to 6% of the overall orbit time.

ROIMUS
In the forward-link of broadband satellite systems with multiple beams, Co-Channel Interference (CCI) can severely affect simultaneous transmissions at equal frequency to users located in different beams. Eliminating the CCI at the receiver, e.g., by an iterative cancellation approach, strongly increases the receiver complexity and cost. Therefore, much effort has been made to cancel the CCI at the cost-insensitive transmitter side (at the gateway), e.g. by Dirty Paper Coding or Tomlinson-Harashima Precoding.
For the return-link, Successive Interference Cancellation (SIC) could be used at the gateway. In this respect novel resource management algorithms have to be designed to better exploit the new characteristics and the improved performance of the physical layer.

The work of AT-One consortium (DLR and NLR) under the Special Agreement was focused on academic research in the fields of the utilisation of new GNSS navigation signals in GPS L1/L5 and Galileo E1/E5 bands in GBAS system, analysis of the threats to the nominal system operation occurring because of the signal distortions in ionosphere as well as due to multipath propagation and radio frequency interference. Also the aspects of the optimal multi-frequency multi-constellation signal processing in a navigation receiver of GBAS as well as monitoring of the system performance and integrity have been studied.

siNafa
Ziel des Projekts siNafa ist es, die Navigation auf Hochseeschiffen sicherer zu machen. Hierfür sollen neue Signale und Frequenzen von allen Navigationssatellitensystemen genutzt werden um die Verfügbarkeit und Genauigkeit des GNSS-Empfangs zu erhöhen. Die Verwendung innovativer Gruppenantennen-Technologie ermöglicht es, die GNSS-Navigation vor Störern und Täuschern zu schützen und das Vorhandensein dieser Signale sicher zu erkennen. Mit Hilfe eines neuen GNSS-Systems mit drei Antennen sollen die Bewegungen und Beschleunigen des Schiffes exakt gemessen werden. Alle Komponenten werden in eine moderne IT-Infrastruktur eingebunden und zusammen mit bordautonomen Navigationsgeräten gekoppelt.

UFO – Unmanned Freight Operations
Unmanned aircraft are gaining more and more importance in the aviation sector. Lately, the point of interest in this specific field is increasingly including civil applications, too. One such civil scenario could be the transportation of cargo with Unmanned Aircraft Systems (UAS) or more precisely, Remotely Piloted Aircraft Systems (RPAS). Today however, there are no defined processes for certification of these kinds of aircraft, yet. The same is valid for the operation of UAS or RPAS in airspace as well as on airports, where legal and technical obstacles remain. The goal of the project Unmanned Freight Operations is hence the development and validation of a concept of operations for unmanned cargo planes.
