Attention smartphone users: the recent launch of the first two satellites for Europe’s Galileo global navigation satellite system (GNSS) could make things a lot more interesting in about four years.

Galileo will deliver real-time positioning accuracy down to one meter range, compared to 10 meters for GPS, the European Space Agency (ESA) states, and it plans to give non-European users access.

Meanwhile, Apple’s new iPhone 4S has a chip that will be able to access Glonass (the Russian version of GPS), Engadget reports. Other manufacturers, including Qualcomm, Samsung Electronics and Texas Instruments, will also support Glonass — and Galileo as soon as it is operational — with new chipsets and software able to receive and integrate all three main GNSS systems.

2008 Elections From the Jan. 3 Iowa caucuses to the Nov. 4 general election, information graphics were a major component of the New York Times election coverage. Interactive maps on the nytimes.com home page and inside the web site were rich with information, but easy to navigate.

2008 Olympics Coverage In August 2008, The New York Times graphics department published more than 30 interactive graphics covering subjects ranging from the Olympic torch to the medal count. The package included graphics produced in advance of the games, plus more than a dozen produced on deadline analyzing results from a vareity of events. Because NBC tape-delayed the showing of many events, these graphics frequently were readers' first visual picture of how a race was won.

Flight 1549 Lands in the Hudson River When U.S. Airways Flight 1549 made an emergency landing in the Hudson River, graphics editors immediately began reporting what happened in the air, building 3-D models of the plane and developing an interactive graphic. The graphic was initially published the same day as the emergency landing, and updated over the next several days as more information was released. Published Jan. 15, 2009

While growth in usage of social media by the public continues to grow unabated, new research shows that social media usage among large companies is leveling off. The research from the University of Massachusetts at Dartmouth shows that corporate use of networks like Facebook and Twitter plateaued in 2011. The study looked at outward facing social media usage by Fortune 500 companies, and found that adoption of blogs, Twitter and Facebook did not rise from 2010 to 2011. Just under 1/4 of the Fortune 500 have a public facing blog. While this is an increase from the 16% measured in 2008, it has not increased at all since last year. Likewise, Twitter usage has only increased by 2% in the last year, from 60% last year to 62% this year. Only 58% of large companies have a Facebook page; however, another 2% rise from last years figure. Astonishingly, 31% have no presence on either Facebook or Twitter at all. This follows research last week revealing that 1 in 5 small business owners hate social media.  Bete noir of the industry was Groupon, with a whopping 70% of SMEs reporting their dislike of the coupon website.

The latest is a survey showing that IT professionals expect tablets to outnumber desktop machines in schools within the next five years.

The results, revealed by a Piper Jaffray analyst, point to the growing popularity of the iPad among technology directors at schools, all of whom are already testing and deploying the device on some level. The survey cited didn't have the biggest sample size (only 25 were polled), but the trend is consistent with other reports we've seen, and certainly Apple has been pushing the device for educational purposes.

Administering the devices from an IT standpoint can be challenging in a school environment, something that's already being felt in the enterprise market. It's an issue that school IT directors are already dealing with in school districts that hand out laptops to students.
