LORAN-C signal termination

LORAN-C was originally developed to provide radio-navigation service for US coastal waters and was later expanded to include complete coverage of the continental US as well as most of Alaska. It was approved as an en route supplemental air navigation system for both Instrument Flight Rule (IFR) and Visual Flight Rule (VFR) operations. The LORAN-C system served the 48 continental states, their coastal areas, and parts of Alaska. The Homeland Security Appropriations Act for Fiscal Year 2010 allows for termination of the LORAN-C signal on January 4, 2010, after certification from the Commandant of the Coast Guard that it
is not needed for navigation and from the Secretary of DHS that it is not needed as a backup for GPS.

Brazil to have GPS landing system

Brazilian airline will be equipping all its aircraft with sensors to allow the
use of the GPS Landing System and Vertical Situational Display. The system
allows the plotting of curved segments in a single procedure, with increased
accuracy and safety, enabling continuous ascent or descent. Vertical Situation
Display enables pilots to accurately identify information on ground relief and
obstacles from the cockpit, by providing an additional tool for monitoring the
position of the aircraft in relation to the ground.

Qantas expands GPS use in flights

Qantas is expanding its use of the latest generation GPS-based navigation
systems to some Melbourne flights. Called as ‘RNP’ – Required Navigational
Performance, it uses GPS to map very precise flight paths to and from
airport runways, which in turn delivers savings on virtually all fronts, from
fuel, emissions, distance, time and even quieter landings.

Russia to equip railways with anti-terrorist attack detectors

A group of Russian scientists has developed detectors to prevent terrorist
attacks on Russian railways. The detectors will use Glonass or GPS,
and are designed for both military and civilian use. Both systems allow users
to determine an object’s position to within a few meters.
