A step closer to safer aviation in Africa

28.02.2003


ASECNA aeroplane used in the trials


Between 24 and 26 February, a number of trial flights into Dakar using the EGNOS (European Global Navigation Overlay Service) Test Bed system were carried out to show how the planned provision of Global Navigation Satellite System (GNSS) services over Central Africa could be implemented.

ASECNA (Agence pour la sécurité de la navigation aérienne en ASECNA (Agence pour la SECurité de la Navigation Aérienne en Afrique et à Madagascar) has worked with the European Space Agency, the European Commission and various other European partners to make these trials possible.
The Africa and Indian Ocean (AFI) States have adopted a three-phase strategy to implement GNSS for aviation in their region in the framework of the International Civil Aviation Organisation (ICAO) APIRG (AFI Planning and Implementation Regional Group).


The Dakar trials represent the first experimental test phase for the introduction of GNSS, which comprises the deployment of mobile EGNOS test stations in the AFI region to extend test signal coverage. These stations will be used to demonstrate an EGNOS service over the AFI land masses.

To provide Approach with Vertical Guidance (APV-1) navigation information is a target of the ICAO GNSS strategy and has been identified as an application of key importance for safer aviation in the region.

The Dakar trials aimed to provide an APV-1 signal in the Dakar area and to verify performance in static and dynamic conditions. To this end, a portable EGNOS test station was installed at Dakar airport and connected to the ESTB (EGNOS System Test Bed) in July last year.

An aeroplane was fitted with Test Bed User Equipment (TBUE) and an OEM4 Millennium NovAtel receiver. This equipment gave the pilots enhanced navigation information which they used to perform approaches. The EGNOS Test Bed Signal In Space provides accurate positioning data with very good availability.

This is the first time an ESTB RIMS (Ranging and Integrity Monitoring Station) has been deployed to test EGNOS services in the sub-Saharan region. Deploying the Dakar RIMS has been beneficial because it not only provides a service in the Dakar region but has enhanced the performance of the ESTB in the Mediterranean and further improved that of the ESTB in the Canary Islands. This has important implications for the provision of EGNOS services outside the European Civil Aviation Conference (ECAC) region.

In the framework of the AFI strategy, the first test bed will be installed in Central Africa and will be followed by others in Southern and Eastern Africa. More extended trials and an associated GNSS workshop, planned for May in Yaoundé, are expected to bring together all participants in the region and raise awareness of Europe’s GNSS.

Im Focus: Biotechnology: Triggered by light, a novel way to switch on an enzyme

In living cells, enzymes drive biochemical metabolic processes enabling reactions to take place efficiently. It is this very ability which allows them to be used as catalysts in biotechnology, for example to create chemical products such as pharmaceutics. Researchers now identified an enzyme that, when illuminated with blue light, becomes catalytically active and initiates a reaction that was previously unknown in enzymatics. The study was published in "Nature Communications".

Enzymes: they are the central drivers for biochemical metabolic processes in every living cell, enabling reactions to take place efficiently. It is this very...

Im Focus: New double-contrast technique picks up small tumors on MRI

Early detection of tumors is extremely important in treating cancer. A new technique developed by researchers at the University of California, Davis offers a significant advance in using magnetic resonance imaging to pick out even very small tumors from normal tissue. The work is published May 25 in the journal Nature Nanotechnology.

Im Focus: I-call - When microimplants communicate with each other / Innovation driver digitization - "Smart Health“

Microelectronics as a key technology enables numerous innovations in the field of intelligent medical technology. The Fraunhofer Institute for Biomedical Engineering IBMT coordinates the BMBF cooperative project "I-call" realizing the first electronic system for ultrasound-based, safe and interference-resistant data transmission between implants in the human body.

When microelectronic systems are used for medical applications, they have to meet high requirements in terms of biocompatibility, reliability, energy...

Im Focus: When predictions of theoretical chemists become reality

Thomas Heine, Professor of Theoretical Chemistry at TU Dresden, together with his team, first predicted a topological 2D polymer in 2019. Only one year later, an international team led by Italian researchers was able to synthesize these materials and experimentally prove their topological properties. For the renowned journal Nature Materials, this was the occasion to invite Thomas Heine to a News and Views article, which was published this week. Under the title "Making 2D Topological Polymers a reality" Prof. Heine describes how his theory became a reality.

Ultrathin materials are extremely interesting as building blocks for next generation nano electronic devices, as it is much easier to make circuits and other...

Im Focus: Rolling into the deep

Scientists took a leukocyte as the blueprint and developed a microrobot that has the size, shape and moving capabilities of a white blood cell. Simulating a blood vessel in a laboratory setting, they succeeded in magnetically navigating the ball-shaped microroller through this dynamic and dense environment. The drug-delivery vehicle withstood the simulated blood flow, pushing the developments in targeted drug delivery a step further: inside the body, there is no better access route to all tissues and organs than the circulatory system. A robot that could actually travel through this finely woven web would revolutionize the minimally-invasive treatment of illnesses.

A team of scientists from the Max Planck Institute for Intelligent Systems (MPI-IS) in Stuttgart invented a tiny microrobot that resembles a white blood cell...
