Spanish researchers create more precise sat-nav system

Researchers in The country have developed a program they say can significantly enhance the precision of car sat-navs.

It brings together a traditional gps (GPS) indication with those of other receptors - accelerometers and gyroscopes - to determine a vehicle's place to within 2m (6ft 6in).

It can be at low costs set up in any car and may gradually perform on cellular phones, the researchers say.

Such a program has the prospective to help the growing driverless car market.

The program was mutually developed and developed by the Used Synthetic Intellect Team and the Techniques Intellect Clinical - both centered at Carlos III University in The city (UC3M).

"We have handled to enhance the dedication of a car place in crucial situations by between 50 and 90%," said specialist Bob Martin.

According to the researchers, the edge of mistake of professional GPS used in automobiles is about 15m in an start area, where the recipient has good exposure from the satellite.

However, in places where the indication bounces off structures and plants, the computation of a car place can be off by more than 50m.

In certain situations, such as in channels, interaction is missing absolutely.

At that point, the program goes back to basically wondering the place. While this may be adequate for in-car systems, it would not be appropriate for computerized automobiles, which are currently being developed by companies Search engines.

"Cars are becoming progressively linked," said Prof Bob Bailey from the Coventry University Business school.

"There is a lot of analysis into driverless automobiles and, for that, GPS needs to be as precise as possible," he included.

The program developed in The city creates use of a device consists of three accelerometers and three gyroscopes, which keep a record of the rate and route of a automobile at all times.

The information from these is along with that from a traditional GPS device to determine a place of a car to within 2m in places.

Using smartphones
The next phase for the Language researchers is to create a program that can perform with cellular phones.

Most are prepared with a variety of receptors, such as an accelerometer, a gyroscope, a magnetometer, GPS and cameras, moreover to wi-fi, Wireless and GSM devices.

"We are now beginning to perform on the incorporation of this information combination program into a cellular phone," said specialist Enrique Marti.

"It can include all of the dimensions that come from its receptors in order to acquire the same outcome that we have now, but at an even much cheaper, since it is something that almost everyone can bring around in their wallet."

Cell phone revenue dropped this year, indicates study

Global revenue of cell mobile phones dropped this year compared with the season before, according to a review from analysis company Gartner.

It said 1.75 billion dollars devices had been bought, tagging a 1.7% decrease.

Analysts at the company suggested "tough economic conditions" had been partially responsible for the fall.

It follows formal information from The country showing its variety of cellular telephone and datacard subscribers dropped by 5% over the same interval.

A review by the Spanish regulator CMT said there were nearly 2.8 thousand less such agreements at the end of the season than at the beginning, with Telefonica's Movistar unit and United kingdom keeping the impact of failures in Dec.

The nation's gdp (GDP) shrank by 1.3% this year, according to its central bank.

Android gains
Gartner's information indicates decline demand for feature mobile phones - lower-end gadgets with limited performance - led to the fall. It said that in the final three months of the season, 264.4 thousand such gadgets had been marketed - 19.3% less than over the same interval this year.

Although mobile mobile phones had seen a 38.3% year-on-year obtain over it all 1 / 4, they had still stayed in the community with 207.7 thousand models marketed, the analysis said.

The company included that Apple and New samsung had taken over the smart phone industry, with a combined 52% discuss in the October-to-December 1 / 4.

"There is no producer that can strongly lay claim to the variety three spot," said the organization's major analysis specialist Anshul Gupta.

"Their direct competitors, including those with similar products, battle to achieve the same brand admiration among customers."

He included that the overall fall in revenue noticeable the first time the industry had shortened since 2009.

Gartner's information also indicated that in it all 1 / 4, Android os had powered 69.7% of all mobile mobile phones marketed, while iOS had included 20.9% of gadgets.

For the season, that noticeable a obtain in discuss for Google os, but a decrease for Apple's - although in terms of models marketed, both firms made benefits.
