Enhanced Differential Loran Maritime Trials in The Netherlands Declared Successful

The eDLoran receiver including antenna is mounted in a standard enclosure (14x14x10cm) for GPS-RTK equipment provided by AD Navigation (Norway)

The Dutch Pilots Corporation and Reelektronika announced today (January 7, 2014) the successful development and test of an Enhanced Differential Loran (eDLoran) backup to GNSS in The Netherlands.

Trials at sea and in the Rotterdam Europort harbor area met the requirement for absolute accuracies in the five-meter range, according to Durk van Willigen, CEO of Reelektronika, and Wim van Buuren, Loodswezen’s information & communications technology (ICT) and innovation manager and board member.

Silver Spring, Maryland USA
√ The USA will stop printing nautical charts next April, the end of a 150 year tradition. Why? “Declining demand, electronic and digital charts and federal budget realities,” said NOAA’s Office of Coast Survey. They will maintain and update PDFs of more than a thousand coastal charts and refer those who admire traditional lithography to private printers who can do the job.

Going for her first big job interview after college, Elizabeth Rooney admits she didn’t know what GPS was.

“It was 1995,” she says, “and I was going in to see about this job. I had been looking at some literature from the company I was interviewing with, and there it was, ‘GPS.’ I wondered what the letters meant when I saw them.”

Due to the huge success of GPS in both military and civil applications, several other GNSSs have been developed, built, and operated in the last few decades. GNSS, regional, and augmentation systems are comprise a growing family that also includes GLONASS, Galileo, BeiDou, and Japan’s Quasi-Zenith Satellite System (QZSS). New members, such as the Global Indian Navigation System (GINS), are preparing to join in next decade.

Urban Positioning on a Smartphone

Urban Positioning on a Smartphone

The poor performance of GNSS user equipment in urban canyons in terms of both accuracy and solution availability is a well-known problem that arises where there are tall buildings or narrow streets. This situation is worse in the cross-street direction than in the along-street direction. (See Figure 1.)
