One of the largest battery wasteers of the And smartphones today, after the screen, is the.

If you turn it on continuously, your device will stop working after a few hours. The reason for this is related to the liver (relatively) Is used to cross-reference signals from 6-12 satellites (usually, but sometimes more) and find the relative position by this data.

The researchers at Microsoft have found a way to reduce the load by moving most of it to servers . The system Which they developed, collects only milliseconds of vital data from the satellites. The rest of the information is collected from data bases on the network, which rely on the user's past locations, when authentication and processing all the data are done on the servers on the Internet.

רכיב Such a small one

The new solution allows a GPS receiver powered by two AA batteries, to give constant location during a year and a half! But it must be remembered that in the connection to the servers , There is also a constant connection to the Internet (a browsing package) - which is a consideration that must also be taken into account in the feasibility of this innovation.

"Applications that use location sensors that are always operating can be very useful, and we can't give them what they need today," says Ji Liu, a senior research scientist at , Believes that systems Low energy consumption will make our devices smarter.

Location data collected in six different locations with the new development

Even before moving some of the cloud computing tasks, researchers used a radio-based clock synchronization platform in North America called WWVB to improve lock speed and reduce the amount of data required. "We built an experimental platform that uses WWVB for time coordination between the To satellites, and as a baseline, "the researchers said." Using this platform, satellite detection takes three times less energy than receivers Exist on mobile devices "

"Typical GPS receivers, despite their widespread distribution, waste too much energy to really be useful for most apps.", "We've noticed that in many cases where location finding is required, location information can be processed later when the information is uploaded to the server. We designed a certain GPS receiver- (Co-GPS) that allows a sensing device to aggressively use the receiver while using minimal pure satellite information and remote server processing "

The study was presented in Toronto during the ACM Conference on Embedded Network Sensor Systems (SenSys). Their research was crowned best at the conference, And is called "Sensing Energy-efficient using cloud resources ”by Ji Liu, Bodhi Freiente, Ted Hart, Hittor Ramos, Antonio A. P. Loriero, and Kiang Wang.

But their development is not the only one. An Israeli company called Cell Guide from Rehovot Science Park has developed a very similar solution. Their receiver uses both satellites and remote servers, which can be (even) your personal PC. The accuracy of their device is impressive, works well in urban areas, and enables continuous operation (Not known which battery) for up to eight consecutive months. Israeli honor.

GPS is a very very useful component. Whether it is used for navigating, measuring data to maintain (During running, for example), or tracking children (or other people), the demand for this ability is increasing. Today, the component is almost in the possession of every man and woman, thanks to the smart phones.

But the real question is: Do we really want location data all the time, and everywhere? Is not this another breach of our privacy? Tell us what you think about the reactions.

  1. In life, I would not think that it is the processing that is the battery
    I was sure that the amplifier and other components of the receiver itself were the ones that drained the battery.

  2. Sending a server request and getting data back takes time
    The location information will be annoying. Not worth it

  3. Stop stealing our lives
    "It collects the rest of the information from network databases that rely on user past locations"

  4. To XXNUM
    Delay in such a case is negligible at most. In such a system that works properly, it should not be more than half a second at worst no matter where you are in the world.
    Hydlay in the existing system is bigger than that.

    The only thing I see is a problem with .. Another system that is completely dependent on the Internet. Internet problem - system is disabled.
    The clouds must be good and beautiful, but you have to think if you want your mobile device to do something on its own, or it will be worth a piece of stone if the network falls.
