Satellite navigation system Galileo will start operating again in the sample


The European satellite navigation system Galileo is ready for a failure now to use again. The disorder had existed since the 11th century. July. The emergency alert SAR work but still.

The trial operation (Initial Services) of the European Galileo satellite navigation system is successfully restored. Galileo was affected by a technical incident in connection with its infrastructure on the ground, reports the German center for air and space travel (DLR). Since the 11. July were users of the regular functions of the European satellite navigation system Galileo is no longer available. On the afternoon of the 11. In July, the European Global Navigation Satellite Systems Agency (GSA) had informed in Prague your customers about the outage.

Use at your own risk

The GSA reported that there was “a deterioration of the services on all of the Galileo satellites and the signals do not meet the minimum requirements of performance” achieved, the Galileo normally promises. Customers used still devices calculate their Position by means of Galileo satellites, would have the “must be at your own risk” do.

In a further communication dated 14. In July, the GSA added that the cause of the breakdown in the ground infrastructure, so don’t be looking at the satellite.

Now, the DLR stated: “The technical incident was due to a malfunction of the equipment in the Galileo control centers, the calculate, tell the time and trains in advance, and for the Processing of the navigation message are used. The disorder has affected various elements in the control centres in Fucino (Italy) and at the DLR site in Oberpfaffenhofen.”

An independent Commission of inquiry under search now for the GSA and the European Commission as a programme responsible authority the closer Umstäönde of failure.

Search and Rescue works

The emergency-rescue service of Galileo, the so-called “Search And Rescue (SAR)”feature that ships in distress or injured climbers the help, it worked, despite the breakdown, undisturbed, asserts the company.

In its final configuration, Galileo will comprise at least 30 satellites

Galileo behind the time – and financial plan

Currently the GSA only offers a at the beginning of service (initial service) of Galileo. This means that the navigation signals originate only from 26 satellites. Only when 30 Galileo satellites are in their final orbit and fully furnished, the European satellite navigation system in the normal operation. The remaining four satellites will be shot up to 2020 in the Orbit.

Galileo – a position determination

Thus, the prestige project of the European Union is significantly behind the original schedule. Initially, Galileo should be already in 2008, fully operational. Even at the expense of the EU was not able to adhere to your Plan. In 1999, they had planned a cost of 2.2 to 2.9 billion euros for the construction of the system. Currently, the Budget provided for in the EU until 2020 for the construction of 7.2 billion euros, plus a further 3 billion euros for the operation.

Two are better than one

The failure casts a spotlight on the vulnerability and risks of satellite navigation systems. Galileo, and, in parallel, ever more refined Global Positioning System (GPS) of the United States should take in the future important tasks in the area of Autonomous driving and flying, as well as in shipping. If, however, Autonomous vehicles, aircraft and ships, each of only a navigation system are dependent, could result in a failure to control failure.

Many receiving devices are therefore designed, signals from multiple satellite providers to evaluate. More complex systems use the detection signals from earth-based radio systems, such as mobile telephone stations. So they are more reliable and less prone to interference.

Autonomous vehicles have the additional environmental sensors, which ensure, that it comes suddenly due to incorrect or missing satellite data to a collision. In principle, military in satellite navigation systems also have the ability to put you in the war or in the event of a crisis out of operation.

    What has happened so far

    Sentinel-1A on 3. April 2014 the beginning. Since then, two more satellites, Sentinel-2A followed on 23. June 2015 and Sentinel-3A at 16. February 2016. This recording of Sentinel-3A is one of his earliest. It shows the Nile river and parts of the Middle East. The satellites measure the energy emanating from the earth’s surface, with a sea and Land surface temperature radiometer (SLSTR).

    This incredibly sharp image shows the coral reefs in the Red sea off the coast of Saudi Arabia. It was from the Sentinel-2A on 28. June 2015 included. The quality of the Sentinel-photos is much better than with previous satellite missions such as Envisat. In the case of the Sentinel-2 Mission to the country is observed. For photos of Vegetation, rivers, creeks and coastline will be evaluated areas.

    Colorized Photos

    This nachcolorierte image from the South of Khartoum in the Sudan was one of the first Sentinel-2A, recorded five days after the satellite arrived in orbit. In the upper right corner you can see a part of the blue Nile. The red dots along the river are dense with Vegetation. The color was later added to the photo to better interpret.

    Another great recording from the Sentinel-2A shows Sierra Leone in West Africa. The capital Freetown is on a Peninsula at the bottom of the image. Your economy is the natural deep-water port-dependent. Scientists at the ESA say that he was threatened by the many unauthorized settlements, for the many acres of mangrove forests were felled.
