It uses a vehicle-mounted camera, object-recognition software and satellite positioning to create detailed 3-D maps of roads, pinpointing features such as pot-holes.
The app works by pinging you each day to ask how you are feeling, then uses satellite positioning (GPS) to track your location.
China's plans to develop a satellite positioning system are thought to date back to 1983 when then-President Ronald Reagan announced plans to build space-based missile-defense systems in what became known as his "Star Wars" speech.
They go into a computer program, along with satellite global positioning coordinates to map -- with precision -- the basic outline.
One is that smart-phones with satellite-positioning baked into them are now widely available, making it very easy for people to broadcast their whereabouts.
Other watches incorporate ultraviolet radiation sensors and satellite-positioning systems.
Mobile phones, some of which are now equipped with satellite-positioning technology (see article), could be used to alert people to the charms of stores or restaurants they are walking or driving past.
Outfitted with 4.3-inch screens, they will also be able to play music and video and will eventually incorporate global positioning satellite data and wi-fi.
Cemex can do this because its trucks are now equipped with dashboard computer navigation terminals that allow tracking by a central dispatch unit using state-of-the-art global positioning satellite technology.
In a study published in 2006, researchers at Carnegie Mellon University who rode 37 airline flights with a radio-frequency measuring device found emissions from cellphones that could interfere with global-positioning satellite systems.
WSJ: 'Turn Off All Electronic Devices:' And What Happens if You Don't
And by using the global positioning satellite network, vessels' positions can be monitored automatically, as is already the case around the Great Barrier Reef in Australia and the Georges Bank off the coast of Maine.
The report calls for accelerating the use of the global positioning satellite system (GPS) in U.S. airspace and ultimately linking GPS and the air traffic control system to provide better and safer separation for planes flying in the United States.
Once there, they use aerial photography and remote cameras in combination with depth-finding and global-positioning satellite technology (as well as some first-hand testing of the waves) to measure the waves and map the contours of the ocean floor under the breaks.
The results were reached via global positioning satellite measurements taken before and after the February 27 quake by teams from The Ohio State University, the University of Hawaii, the University of Memphis and the California Institute of Technology, as well as agencies across South America.
While the participants engaged in much discussion there of Iraq, trade and other issues, the most significant result of the meeting may have been an agreement to ensure that Europes Galileo navigation system does not interfere with the frequencies used by Americas Global Positioning Satellite (GPS) system .
Look at Garmin, which commercialized a technology with roots in defense: satellite-based global positioning.
Inside, Williams explains, is a receiver tailored to make use of a signal from an atomic clock carried by a global positioning system satellite.
Look at Garmin (nasdaq: GRMN - news - people ), which commercialized a technology with roots in defense: satellite-based global positioning.
The study, the first of its kind to use the satellite-based global positioning system to provide the animals' locations, involved tagging 14 African elephants with sophisticated radio collars and monitoring their movements for several months.
Just one year ago, the Bush administration announced it would keep the ground-based LORAN system operational to serve as a backup for the satellite-based global positioning systems, which are becoming ubiquitous in cars, planes and ships.
Apple has used wi-fi location data for years to try to help users pinpiont their location, without having to rely on the satellite-based global positioning system a feature Apple has bragged about in the past.
Each onboard ADS-B set consists of a Global Positioning System satellite navigation unit, two Pentium microprocessors, some software and a radio transmitter-receiver--not much more gear than you would find behind the dash of a new Cadillac.
It also wants to build its own satellite-driven global-positioning system to rival America's, which everyone now uses.
So Ted Stevens may have saved my life and that was something a great many Alaskans could say as they looked about at the roads and bridges, the hospitals and flood-control systems, the satellite weather and global-positioning relay stations, the sprawling Army and Air Force bases, the rural landing strips and postal air-cargo flights that sustain existence in Alaska as it enters its fiftieth year of statehood.
Our investment in space exploration helped to create our satellite telecommunications network and the Global Positioning System.
CNN: Bush: 'It is time for America to take the next steps' in space
Even today in the world of satellite based GPS and the fairly exact positioning information it can provide, it is always best to have a paper chart or map and the needed tools in case your electronic ones fail so you are not left stranded and unable to find your way home.
She said that US diplomats and scientists should ensure that the Global Positioning System should become the world's standard satellite navigation system.
There have been a few anecdotal concerns raised over the last several weeks that LightSquared's proposed LTE network -- which would repurpose L-band spectrum formerly used for satellite -- is too close to the spectrum used by the Global Positioning System, leading to unintentional jamming when the towers overpower the much weaker GPS signals.
ENGADGET: US Air Force raises concerns over LightSquared's LTE network messing with GPS
We questioned the starry-eyed revenue and expense forecasts for Galileo, a European satellite navigation venture designed to compete with the U.S.' Global Positioning System.
