HiGAIN - Ubiquitous High Accuracy and Integrity Navigation
Mobility applications such as air cabs, autonomous drones and cars, ships (especially in ports), and trains require accurate and reliable navigation solutions to safely shape the future of transportation on land, sea, and air. In order to achieve the positioning and navigation requirements demanded by the various user groups in terms of their performance, availability and reliability (especially integrity), difficult technical challenges have to be overcome due to the very challenging environments in which accurate and reliable positioning is required. For example, poor visibility and shadowing of GNSS satellites in street canyons and tunnels, as well as radio frequency interference and multipath propagation of GNSS signals in urban environments, require navigation solution concepts that go beyond standard GNSS solutions.

SIROM
Space based GNSS measurements become more and more a significant data source for observing the ionosphere. Radio occultation and topside measurements can cover remote areas where ground-based GNSS reference networks are not available. Covering those areas is crucial for the understanding of ionospheric processes with their highly dynamic temporal and spatial changes. We will furthermore investigate and exploit the potential of space-based data for 3D modelling of the Ionosphere in near real-time.

INSIGHT-II
Accelerometer measurements are used in two major topics in Earth observations, namely gravity field recovery and thermosphere studies. We have shown that the thermospheric signatures in the GOCE gravity gradients are due to an unexpected quadratic response of the instruments to the accelerations acting on the satellite. A hypothesis has been worked out, implying the fact that the quadratic factor and other disturbances seen on the accelerometers are coupled together. This hypothesis will be evaluated further, strengthened in experiments and the impact on gravity field recovery as well as thermosphere and ionosphere studied. For gravity field this means an improvement of the GOCE satellite only gravity field by reducing the noise in the gradients and recalibrating the gradiometer. For the Swarm satellite mission, this means an enhancement of the scientific outcome of the accelerometer data by studying high amplitude signals in times of ionospheric storms. An elaborated data processing schema is necessary to make use of these instruments, so an uncertainty estimation procedure will we established evaluating the quality of the retrieved neutral density. Assimilating the neutral density into a physical based ionosphere-thermosphere coupling model the dynamics in the ionosphere at times of storms can be studied. As validation is very important a validation concept is worked out. Therefore, an empirical ionosphere model is enlarged further.

GALANT
Future navigation services provided by upcoming satellite systems like Galileo will require corresponding improvements of the receiving systems. Particularly, interference and multipath signals may cause a significant degradation of the performance and thus make it impossible, to obtain exact and reliable positioning data. These restrictions and uncertainties cannot be tolerated for Safety-of-Life (SoL) applications e.g. in aeronautics and shipping. In order to overcome this problem, adaptively steered antenna arrays are employed, which enable the use of new beamforming and signal processing algorithms. They provide a more exact and reliable navigation solution, by suppressing interferences and multipath signals and improving the reception of the information signal from the direction of the satellite.

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.

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.

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.

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.

COLT - Coding for Laserlinks through the Atmosphere
Laser communication through the atmosphere is impaired by turbulences in the atmosphere. This effect, known as scintillation, causes fades in the received power and outages in the laser communication for several milliseconds. Due to the high data rate in the order of 1 Gbit/s and beyond, bit error bursts of 1 Mbit and more can be observed. To compensate for this effect, DLR developed a packet level coding scheme, whose code words are longer than such error bursts and thus able to correct the long error bursts in the best possible way without the need of an interleaver. The objective of the project COLT is to design, implement and demonstrate a FPGA based packet level coder and decoder for data rates of about 1 Gbit/s.

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).

EECNS - Essential and Efficient Communication Navigation and Surveillance Integrated System
Communications, Navigation and Surveillance (CNS) systems provide the invisible and often unappreciated infrastructure which is essential for Air Traffic Management. CNS enables efficient navigation and safe separation in all phases of flight. The SESAR Concept of Operations aims to dramatically increase the exchange of information between airspace users, air traffic control and flow management. This is expected to improve the quality of service to the travelling public, whilst reducing cost and environmental impact. Although current CNS systems are mature and generally providing a good service, they have not yet fully transitioned from analog to digital technologies. Such a shift is needed to meet the challenges of the coming years; to accommodate higher levels of traffic and improve operational efficiency. Many CNS technologies have been developed in a modular fashion. As a result a transition to network thinking is needed to overcome the inefficiencies of fragmented services whilst supporting local needs. Building on the experience of SESAR1, the EECNS will develop an integrated suite of CNS solutions to meet the operational requirements of the ATM system in the short, medium and long term, with technologies that are consistent with the European ATM Master Plan and the ICAO Global Air Navigation Plan.

Systems for maritime traffic routing and safety”
Background: The subproject “Systems for maritime traffic routing and safety” is part of the joint project “R&D and Real Time Services for maritime Safety and Security” (FEMS/EMS) initiated by the DLR to bunch the institutional forces and to achieve an interdisciplinary completion of research and development activities in both topics (Safety and Security). Safety in the maritime system stands for an incident and accident free operation of within taken place transport and production processes to ensure the protection of life, goods, and the marine habitat. The implementation of security measures into the maritime system is driven by the necessity, to prevent transport and production facilities from destruction (vandalism, terrorism) and to avoid their misuse (piracy, bootlegging).

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.

PACS - Prototypes for Advanced Access Schemes
After being used in communication systems for decades now, random access systems attract new attention, going far beyond providing a channel access for log-on, or signaling. The new paradigm of machine type of communications, where thousands of terminals sporadically transmit small data packets, raised the attention to the efficiency of the channel access policy. Orthogonal schemes that allow transmitters to communicate without the interference of the others, require communication overhead difficulty justified with huge population and small data packets. Random access is therefore, a suitable candidate to address these scenarios, thanks to its flexibility and simplicity, especially at the user terminal side. Recent enhancements leveraging on proactive replication of packets and interference cancellation has brought to drastic performance improvements compared to the well-known ALOHA and Slotted ALOHA (SA) protocols. After a first screening of the available access schemes suitable for machine type of communications via satellite, the most interesting access policy is selected for a first testbed implementation.

RHINOS - Railway High Integrity Navigation Overlay System
RHINOS (Railway High Integrity Navigation Overlay System) supports the safety-critical train localization function for train control in emerging regional and global markets. The RHINOS pillar is the GNSS infrastructure realized for the aviation application with additional layers that meet the rail requirements in the difficult railway environments. The Rhinos ambition is a positive step beyond the proliferation of GNSS platforms, mainly tailored for regional applications, to favor a global solution to release the potential benefits of the EGNSS (GALILEO and EGNOS) in the fast growing train signaling world market. The RHINOS work program includes the investigation of candidate concepts for the provision of the high integrity needed to protect the detected position of the train, as required by the train control system application. Moreover local augmentation elements, ARAIM techniques and other sensors on the train are the add-on specific assets for mitigating the hazards due to the environmental effects which dominate the rail application. A further objective of RHINOS is to contribute to the definition of a standard for the Railway High Integrity Navigation Overlay System leveraging on the EU-US Cooperation Agreement on ARAIM.

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.

TechTIDE
In the frame of the Horizon 2020 (H2020) call of the European Commission (EC), the project “Warning and Mitigation Technologies for Travelling Ionospheric Disturbances Effects” (TechTIDE) develops a system for the detection and monitoring and alert for Travelling ionospheric disturbances (TIDs). TIDs constitute a threat for operational systems using HF or transionospheric radio propagation. TIDs can impose disturbances of an amplitude of 20% of the ambient electron density and a Doppler shift of the level of 0.5Hz. Consequently, the direct and timely identification of TIDs is a clear customer’s requirement for the Space Weather segment of the ESA SSA Programme. The objective of this proposal is to address this need with setting up an operational system for the identification and tracking of TIDs, the estimation of their effects in the bottomside and topside ionosphere and for issuing warnings to the users with estimated parameters of TID characteristics. Based on the information released from this warning system, the users, depending on their applications, will develop mitigation procedures.

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.
