The LightSquared US Company has been autorized by US Federal Communications Commission (FCC) to develop a 4G broadband telecommunications network neighbouring the GPS ones. If filtering is acceptable in GPS band, it is not enough (RF) for aeronautics receivers. This has been verified by Thales which confirmed that landing operations should be compromised. FCC autorization has been cancelled and LightSquared is in liquidation.

The very large passengers ships´ problems

The passengers ships size is always growing and their capacity can reach at least 6000 passengers and 2000 ship´s crew. Among a lot of problems, the most important is certainly the emergency escape of 8000 persons in the case of a major damage compromising the ship´s buoyancy. Among these reflexions one is relating to the improvment of the ship´s water tightness.

 

        

GNSS vulnerabilities: Testing the Truth

GNSS have become embedded in all transport systems and others as timing, communications,…without any catastrophe…just now. But do we need a catastrophe to take in account their vulnerabilities ? What vulnerabilities? What countermeasures?

On 11 March 2011, an earthquake of magnitude 9 on the Richter scale struck Japan, followed by a 10 metre tsunami. The impact moved Japan’s main island of Honshu 2.4 metres to the west. Sendai was the closest port to the earthquake and the city most devastated by the following tsunami.  Captain Kusanagi’s vessel was unloading crude at the Sendai terminal when the earthquake struck.

Strengthening and streamlining the passenger and cabin baggage screening process is a significant priority for airline and airport stakeholders such as the International Air Transport Association (IATA) and Airports Council International (ACI). ICAO remains fully engaged with these and other sector partners in the development of future checkpoint recommendations and associated screening processes. An ICAO Workshop on the Next Generation Passenger and Cabin Baggage Screening Process and Checkpoint, hosted by IATA and ACI in Geneva in late 2010, identified ten key work-streams for stakeholder action and attention in this area and created a new Technical Advisory Group (TAG) to review related technologies and procedures. The Journal spoke recently with James Pope, Chairman of the new TAG and Director of Aviation Security Regulatory Affairs at Transport Canada, Craig Bradbrook, Director of Security and Facilitation for ACI World, Ken Dunlap, Security and Travel Facilitation Director for IATA, in addition to Steven Berti and Anda Djojonegoro of the ICAO Secretariat, about the work and priorities ahead as air transport seeks a more harmonized checkpoint approach that is fully effective in addressing evolving threats to civil aviation while respecting passenger privacy and convenience.
