DENISE

The DENISE project aims at designing and demonstrating, both via laboratory tests and field trials using W2A satellite, a suitable S-band interactive system capable of efficiently using the available bandwidth (15 MHz in both uplink and downlink for each of the two licensed European S-band operators) to provide:
• Interactive mobile broadcast services enhancing the DVB-SH offer,
• Messaging services for handhelds and vehicular terminals, capable of serving millions of terminals thanks to a novel optimised air-interface in the RTN link,
• Real-time emergency services such as voice and file transfer, mainly addressing institutional users on-the-move such as fire brigades, civil protections, etc.

Dependable Navigation

Reliable and ubiquitous positioning and navigation is of central importance for many applications in economy, mass market, and sovereign tasks. With the ongoing development of EGNOS and Galileo, Europe makes a significant contribution to the global provision of navigation infrastructures and will create first prerequisites for a wide spectrum of new positioning, navigation and time services.

e-Triage

Main objective of the project is the design and demonstration of a system for the electronic registration of affected persons in a mass casualty incident (MCI). The e-Triage system is particularly applicable to large-scale disasters but can also be used in individual emergencies, i.e. for regular rescue service. The goal is to provide a communication and database system for everyone involved in the rescue, transport and placement of victims in hospitals and temporary lodgings.

ETSI BSM Emulator

The project provides a basis for the study and the design of an Emulator for an ETSI BSM-Compliant SI-SAP Interface. The work will be based on an existing simulator of Satellite Dependent layers (DVB-RCS/S2), available at DLR; the partners will implement the required modifications in it, and will develop new modules, in order to enable the real-time emulation of a DVB-RCS/S2 network with an SI-SAP-compliant access interface. It will be possible to use the emulator with real computers and real software applications (web browsers, VoIP clients, etc…).

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.

Galileo SEIOT

The acronym Galileo SEIOT is standing for Galileo IOV Signal characterisation and Extended In-Orbit Tests. End of 2011 the first Galileo IOV satellites shall be launched. A further launch is planed to begin of 2012. The Galileo IOV satellites will be the first satellites in the Galileo program which synchronously transmit the operational Galileo signals in all three frequency bands. Aim of the project Galileo-SEIOT is the analysis of Galileo IOV satellites in terms of detailed signal characterization and Extended In-Orbit-Tests.

Galileo SMF

The acronym Galileo SMF ist standing for Signal Monitoring Facility for Galileo FOC Phase. To the beginning of 2011 the institute was mandated to provide a measurement and analysis service in cooperation with the GSOC for the Galileo FOC satellites. Aim of the project is to provide the European Commission represented by European Space Agency and their industry partners (Thales Alenia Space) an independent possibility for measurement of the Signal-in-Space (SIS) of the Galileo satellites after their launch and the In-Orbit Test (IOT) phase.

GeReLEO

Both for TT&C and for many mission applications, such as e.g. earth observation, low-earth-orbit (LEO) satellites require data links with access times that are as long as possible. Long access times to LEO satellites can be realized in a very elegant way via GEO data relays, which are furthermore suited to eliminate the need to utilize costly world-wide networks of ground stations. The project GeReLEO strives to develop and demonstrate novel Ka-band access and transmission schemes as well as a novel Ka-band multibeam receiving antenna. These system components form the key technologies for advanced low and high data rate Ka-band GEO data relays for LEO satellites.

KOMPASSION

For the transport of persons and goods on the road and by train as well as in aeronautics and maritime traffic the accurate and reliable positioning with existing and future satellite systems such as GPS and Galileo is of eminent importance. The high requirements, however, in particular regarding safety from interference, cannot be fulfilled with commercial receivers any more. An alternative is the use of receiving systems that employ array antennas in connection with suitable algorithms for adaptive beamforming and steering (e.g. digital beamforming, DBF), which have proven to suppress jammers, interferes and multipath signals very efficiently.
