GNSS hardening against interference

GNSS receivers are vulnerable to interference, due to the low received signal powers. These low signal power levels motivate the use of spread spectrum techniques. It has been shown that unintentional RF interference (RFI) is ubiquitous. In close proximity to the GNSS frequency bands, services are active for satellite communications, TV broadcasting, radar and Ultra Wide Band (UWB) applications. These services can cause out-of-band emissions, harmonics or inter-modulation products. The weak signal environment, presence of intentional and unintentional interference and the use of GNSS in critical applications argue for an impact assessment of RFI.

NTSB Delta Mariner accident report

On 14th May the National Transportation Safety Board (NTSB) announced from Washington that it had determined that the 2012 allision of mv Delta Mariner with the Eggner’s Ferry Bridge in Kentucky was caused by the reliance of the vessel’s bridge team on the independent contract pilot who provided incorrect navigational direction. Contributing factors included the failure of deck officers on the vessel to use all available navigation tools to verify the vessel’s position and proper route under the bridge; the failure of the crew to prepare an adequate detailed passage plan; and, the lack of effective management and oversight of the bridge lighting system.

BP Shipping Marine Distance Tables

A recent upgrade to AtoBviaC’s end user applications for the BP Shipping Marine Distance Tables now means that users can adjust routes and obtain distances to match their own operations. The changes make it possible for the user to produce deviation reports following changes in voyage destinations.

Tanker owners, operators, charterers and shipmasters are often faced with evaluating changes in trading patterns due to geo-political events and oil supply and demand imbalances. They are used to relying upon AtoBviaC’s BP Shipping Marine Distance Tables to provide accurate and viable distances, based on actual routes, to estimate true costs and to maximise potential profit.

JNC 2013 cancelled

Lisa Beaty, Executive Director of the (US) Institute of Navigation announces with sincere regret that the Institute of Navigation (ION) Military Division must cancel this year’s Joint Navigation Conference (JNC) in Orlando, Florida, originally scheduled for 10th to 13th June 2013.

Apparently this decision has not been taken lightly, but due to the Department of Defense recent policies detailing actions to be taken to prepare for drastic budget cuts, the curtailment of travel, fallout from a scandal with GSA conferences this past year, the current sequestration, and possible furloughs for federal employees, it is no longer possible for ION to ensure the JNC will be
able to maintain a high quality technical program and sufficient networking opportunities that makes the JNC so valuable to Department of Defense / Department of Homeland Security employees and their supporting organizations.

PENS Intre-centre coordination in Europe

It was announced from Brussels on 5th March that the Pan European Network Service (PENS) is now the operational network for the exchange of coordination messages between the Air Traffic Control (ATC) Centres of NATS in Swanwick (UK) and the Maastricht Upper Area Centre (MUAC) in The Netherlands. PENS allows ATC Centres to exchange flight information data securely and efficiently by using IP (Internet Protocol) Version 6 (IPv6) as required by the Flight Message Transfer Protocol (FMTP) Implementing Rule.

Information exchanges between flight data processing systems are established between air traffic control units for the notification, co-ordination and transfer of flights as well as for civil-military co-ordination.

These information exchanges need appropriate and harmonised communication protocols to secure their interoperability – and PENS provides this service.

Satellite controlled trains

Taking a cue from how ESA controls satellites, Spanish railways now have their own high-tech upgrade to keep travellers abreast of when the next train is going to arrive.

Drawing on sophisticated software that keeps satellites on track, the system was developed by a group of Elecnor Deimos engineers who had worked extensively on ESA projects. The outcome of this technology transfer is that up-to-date train schedules are now displayed at over 400 Spanish stations.
