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.
IMPACT - Intelligent Magnetic Positioning for Avoiding Collisions of Trains
The aim of the project IMPACT ("Intelligent Magnetic Positioning for Avoiding Collisions of Trains") is the research and prototypical implementation of a reliable and highly available localization system for railway vehicles that is independent of dedicated infrastructure and based on methods taken from the area of artificial intelligence (AI).
R-Mode Baltic and R-Mode Baltic 2
The projects Mode Baltic und R-Mode Baltic 2 will setup in the Baltic Sea the world-wide first testbed for the new maritime terrestrial backup system, R-Mode, that utilises two so called maritime signals-of-opportunity at once. This is an important step towards the resilient provision of Positioning, Navigation and Timing (PNT) information on-board a vessel which is requested by maritime organisations. The institute will focus in this project on the R-Mode signal design for ranging transmissions in medium and very high frequency band, development of methods for range and position estimation, theoretical analysis and tests of R-Mode in-band synchronization, integration of R-Mode into a PNT data processing unit and international standardisation of R-Mode. Extensive static and dynamic test are planned. The DLR leads this Flagship projects of the EU Strategy for the Baltic Sea Region (EUSBSR). Project partners are national maritime administrations, research institutions and industry from four European countries.
The joint project ROSANNA is based on the results of the research project KOSERNA and the concept study ROSANNA-Konzept and applies them to safety-relevant areas of satellite navigation. Two promising, safety-critical applications were identified that require high-precision and particularly robust navigation: The automotive sector, especially with regard to fully automated and driverless driving, manoeuvring and transport, as well as unmanned aerial vehicles (UAV). Both applications pose special challenges that require fundamental investigations. Promising preliminary studies were successfully carried out within the framework of ROSANNA-Konzept, which are now to be translated into practical designs and suitable demonstrators. The Institute KN is mainly engaged in the challenges resulting from the use of adaptive antennas on UAVs. These include light and compact antenna systems, tracking loops, inclusion of additional sensors as well as interference from the platform and spoofing signals. The project also serves to gain scientific competence in the field of installed antennas as well as the influence of vibration and rotors and their consideration in beamforming, direction-of-arrival estimation and interference suppression.
V2X-DuRail - Vehicle-to-Everything - Funk für digitale, urbane Zugkommunikation
Erhebung von Daten zur Koexistenz von intelligenten, vernetzten Verkehrssystemen im Straßenverkehr und Schienenverkehr in Städten
X2Rail ist eine Reihe von fünf Projekten, die Teil der Initiative Shift2Rail sind. Bei diesem Programm handelt es sich um eine europäische Eisenbahninitiative, mit der gezielte Forschung und Innovation (F&I) sowie marktorientierte Lösungen angestrebt werden, indem die Integration neuer und fortschrittlicher Technologien in innovative Eisenbahnproduktlösungen beschleunigt wird.
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.
