GNSS Technologies
Galileo and GNSS receivers signal processing techniques application development for terrestrial, aeronautical and space fields.
DEIMOS activities in the GNSS Technologies section range from GNSS receiver (mainly focused in Galileo and its new issues) at signal processing level to applications development for terrestrial, aeronautical and space fields (varying from classic GPS navigation to more sophisticated applications, such as using GNSS signals for Earth Observation, or radio-frequency relative navigation for formation flying).
In particular, the following fields of activities are performed:
- GNSS (GPS and Galileo) receivers Signal Processing techniques
- Navigation algorithms and applications
- GNSS receiver simulation
- GNSS System integrity
- Hybridisation techniques and inertial aiding
Several projects have been undertaken by DEIMOS leading to the production of GNSS System Simulation SW, GNSS receiver SW and Analysis Tools, including also accurate GNSS Environment Modelling and Navigation algorithms.
Sub-areas of expertise:
Developments for ESA:
- Galileo Test User Segment for ESA. Development of the Off-line Analysis Tool, signal Processing Design and trade-offs for the Septentrio Test User Receiver
- GNSS+ Study for an autonomous satellite navigation system, based on additional ranging measurements between Galileo satellites or even between Galileo and auxiliary satellites (inter-satellite links), bringing benefits in terms of orbit and clock determination, directly translated into improved figures of integrity, availability and continuity.
Research activities for the Galileo Joint Undertaking concerning the Galileo User Receiver development:
- GRANADA SW receiver in the frame of the GARDA project managed by Alcatel Alenia Space Italy. GRANADA is a test-bench for integration and evaluation of receiver technologies and SW receiver as asset for GNSS application developers
- Galileo Integrated Receiver for Advanced Safety Of Life Equipment (GIRASOLE), lead also by Alcatel Alenia Space Italy. The project aims at safety critical user segments as the aviation, maritime and railroad segments, whose applications or operations require stringent performance levels. DEIMOS is currently investigating Signal Acquisition, Multipath Mitigation techniques and developing a Multi-system GNSS Integrity Application.
- GR-POSTER (Galileo Ready Position Terminal) for the Mass-market receiver, led by ST Microelectronics (Italy). DEIMOS role is focused on the Core Technology analysis, ion and development, addressing the reception of GNSS signals in weak signal environments, as well as the receiver Testing Tools specification.
- GRAIL, GNSS introduction in the RAIL sector. This project led by INECO is aimed to demonstrate the effective benefit and implication of the adoption of Galileo Receiver in rail applications. DEIMOS contribution focuses on the system test-bench
- ATENEA is a project realised by an international consortium led by DEIMOS Space (with participation of DEIMOS Engenharia), dedicated to design advanced techniques of navigation for professional applications, using GNSS, INS and LiDAR. This approach is valid for a large rank of applications in hard environments, having ed the Urban Cartography as case of reference. ATENEA will show how the joint use of Galileo signals, integrated positioning and measures processing can solve the severe technical problems in these environments, providing precision and robustness, and reducing the system cost.
- ENCORE is a high performance code receiver for agrarian applications in Brazil. DEIMOS Engenharia leads this project, financed partially by the GSA within the framework of international relations with non-European countries, with participation of DEIMOS Space. The main objective of the project is to introduce Galileo terminals in the Brazilian market for agrarian applications, geo-reference and cadastre. The project, with the participation of several Brazilian and European partners, includes an application based on a GNSS receiver of high performance and low cost that uses the novel MBOC and AltBOC Galileo signals characteristics.
