The backpack-mounted Enhanced Mapping and Positioning System (EMAPS), being tried out aboa...

Mapping environmental threats in GPS-inaccessible locations – such as underground installations, or the passageways of ships – can certainly pose some challenges. While there are robotic systems that can do the job, robots aren’t necessarily the best choice for cramped quarters or uneven terrain. That’s why a team of scientists at Johns Hopkins University have developed the backpack-mounted Enhanced Mapping and Positioning System ... or EMAPS.  Read More

BikeSpike is a device that adds an extra layer of security to bicycles by enabling cyclist...

Bicycles are a notoriously easy target for thieves, but technology is here to help in the form of a new device that promises to help cyclists safeguard their property and recover it if stolen. Currently seeking funds on KickStarter, the Chicago-based BikeSpike team has designed a GPS tracker that features a built-in antenna, an on-board accelerometer and a connection to a GSM mobile phone network that allows users to keep tabs on their bike via a smartphone or computer.  Read More

The prototype is somewhat portable, but not quite lightweight

Todd Humphreys and his students at the University of Texas in Austin are tired of waiting for augmented reality that meets the promise of the technology we've been hearing about and seeing in science fiction for years now. So they set out to build it themselves, and presented a very rough prototype for the first time at the South By Southwest Interactive Festival (SXSW) in Austin on Friday.  Read More

UC3M's combined GPS unit and inertial measurement unit

Many of us use our vehicle navigation systems on a daily basis, and as self-driving cars come into common use – assuming they do – such systems will become even more important. Unfortunately, however, the GPS technology that’s integral to vehicle navigation can be thwarted by obstacles such as tall buildings. A team of researchers at Spain’s Universidad Carlos III de Madrid (UC3M) are attempting to address that problem, with a system that is said to drastically boost GPS accuracy in city driving.  Read More

Scandinavian researchers have trialled a GPS application to aid in giving care to dementia...

Researchers at Scandinavia’s largest research organization, SINTEFF, have been trialling a prototype GPS application to track dementia sufferers living at home, in institutions, and in other forms of shared accommodation facilities. The project has seen more than 50 dementia sufferers using the system for periods of up to a year and according to the researchers, people equipped with it felt safer, had more freedom to move around and enjoyed better quality of life.  Read More

The Combat Survivor Evader Locator (CSEL)

Boeing has been awarded contracts worth US$13.6 million to upgrade the U.S. Air Force’s Combat Survivor Evader Locator (CSEL) radio and the CSEL ultrahigh frequency (UHF) base stations that support it. The purpose of the contract is to bring the personal survival radio and the CSEL network in line with the latest Information Assurance standards to protect them against jamming and other interference by hostile forces.  Read More

The Locata system installed at the White Sands Missile range

As anyone who's tried to use GPS indoors can tell you, global positioning systems have their limitations. For them to work properly, you have to be outdoors and you need a clear view of the sky. If you’re in the military, you also have to be sure that the enemy isn't jamming the satellite signal. For this reason, the US Air Force has awarded Canberra-based firm Locata a “sole source” contract to install a ground-based version of GPS over 2,500 square miles (6,475 sq/km) of the White Sands Missile Range in New Mexico as part of a program to develop a practical supplement to GPS.  Read More

KAIST researchers have developed an indoor positioning system based on 'Wi-Fi fingerprints...

Researchers at the Korean Advanced Institute of Science and Technology (KAIST) have developed a new indoor positioning system that makes it possible to build a Wi-Fi radio map that does not require GPS signals. It's claimed to be an improvement on Wi-Fi Positioning Systems, that rely on both GPS and Wi-Fi signals.  Read More

Leikr shows your position on a color map

One of the big sports-based breakthroughs of 2012 was the integration of GPS navigation into sports watches. Watches like the Garmin Fenix and Suunto Ambit offer users the ability to create tracks and navigate routes from the wrist. We're barely into 2013, and the GPS sports watch has made another big step: color mapping.  Read More

Rogue nuclear tests can be detected in GPS and radio telescope adjustment noise (Image: Sh...

Given that rogue nuclear tests are always conducted underground, the search for them has focused on efforts to refine the identification of characteristic seismic signatures. Now, researchers at Ohio State University (OSU) have discovered new detection methods in unlikely places – the rejected noise in GPS measurements and radio astronomy.  Read More
