A ground-based system that uses much stronger signals than GPS can find your location in cities and indoors. It is a new positioning system that could compete with GPS to make sure you never lose your directions again.
Instead of satellites, Locata uses ground-based equipment to launch a radio signal over a localized area that is a million times stronger on arrival than GPS. It can work indoors as well as outdoors, and the makers claim the receivers can be shrunk to fit inside a regular cell phone. Even the US military, which invented GPS technology, signed a contract last month agreeing to a large-scale test of Locata at the White Sands Missile Range in New Mexico.
“This is one of the most important technology developments for the future of the positioning industry,” says Nunzio Gambale, CEO and co-founder of the firm Locata, based in Griffith, Australia.
As for the Locata’s accuracy, Christopher Morin of the US Air Force tested it recently at White Sands, and it worked to within 18 centimeters along any axis(轴). Morin says it should be possible to get the resolution down to 5 centimeters.
Admittedly, the tests were performed in an open desert where GPS also works beautifully, but its signals are weak— like a car headlight from 20,000 kilometers away— and easily blocked by solid objects. “Locata’s signal is far stronger, though not guaranteed to work in a complex urban environment,” says David Last, consultant to the UK’s General Lighthouse Authorities.
“Locata’s technology will face competition in the race to transform indoor navigation. But it could shine in specific areas,” Gambale says. “Robots with Locata could easily navigate inside buildings without the complex optical systems they need at the moment. And process that handle precise location data could not only guide you around a mall, railway station or airport, but also take you to the exact shelf in a shop for the product you want. The units small and cheap enough for smart phones should be available within five years— a similar path to the one GPS took on its way towards world domination.”

A ground-based system that uses much stronger signals than GPS can find your location in cities and indoors. It is a new positioning system that could compete with GPS to make sure you never lose your directions again.
Instead of satellites, Locata uses ground-based equipment to send a radio signal over a localized area that is a million times stronger on arrival than GPS. It can work indoors as well as outdoors, and the makers claim that the receivers can be shrunk(缩小) to fit inside a regular cell phone. Even the US armies, which invented GPS technology, signed a file last month agreeing to a test of Locata at the White Sands Missile Range in New Mexico.
“This is one of the most important technology developments for the future of the positioning industry,” says Nunzio Gambale, CEO and co-founder of the firm Locata, based in Griffith, Australia.
As for the Locata’s correctness, Christopher Morin of the US Air Force tested it recently at White Sands, and it worked to within 18cm along any axis(轴). Morin said it should be possible to get the exactitude down to 5cm.
The tests were performed in an open desert where GPS also worked beautifully, but its signal was weak—like a car headlight from 20,000 kilometers away—and easily cut off by solid objects(实心的物体). Locata’s signal was far stronger, though not guaranteed to work in a complex urban environment, said David, speaker of the UK’ s General Lighthouse Authorities.
Locata’s technology will face competition in the race to transform indoor navigation. But it could shine in specific areas, Gambale said. Robots with Locata could easily navigate inside buildings without the complex optical(视觉的) systems they need at the moment. And the process that handles correct location data could not only guide you around a mall, railway station or airport, but also take you to the exact shelf in a shop for the product you want. It would be small and cheap enough for smart phones and it should be available within five years—a similar path to the one GPS took on its way towards the world, he said.

2.Which of the following is NOT true about Locata?
A. Without the help of the satellites, Locata can tell you where you are.
B. Locata will be popular with most people even including the US armies.
C. Locata has a better signal than GPS in some bad environments.
D. In five years, Locata will take the place of GPS.
3.According to the passage, Gambale______.
A. did the experiment at White Sands last month
B. believed the Locata would help to develop smart robots’ creation
C. doubted whether Locata can work in a complex environment or not
D. was worried about the competition the Locata faced
4.Which of the following can replace the underlined word “exactitude” in Paragraph 4?
A. Accuracy. B. Speed.
C. Determination D. Length
5.What can we know from the passage?
A. Locata is as small as a cell phone.
B. GPS is the most practical position system at present.
C. Locata will tell you how to get what you want in the future.
D. Locata will enter our lives through the cell phone, just like GPS.
