  Whether you use Apple or Android, when installing most software, you can pop up such a prompt: "Allow positioning information?". After allowing, the software can provide more targeted and accurate services, and this process is mainly achieved through GPS technology.

  However, there are also positioning errors in GPS positioning, and for the civilian field, this value is about 10 meters. According to reports, a team of researchers from the University of California said they had reduced this accuracy to 1 meter.

  10 meters: a bit accurate but a bit inaccurate.

  By receiving at least 3 of the information sent out of the 24 satellites, including the position of the satellite and the time of the signal, we can use three radius and draw three sphere in the space, and your position is in your position is in the space. Three spherical point of intersection.

  Because the GPS uses the mid -range earth surround orbit, the distance leads to the unavoidable existence of errors. Even if the data of more than 3 satellites is superimposed, the best positioning error is about 10 meters.

  Because GPS is actually developed and maintained by the US Department of Defense, it inevitably involves military factors. In the earliest, because they were afraid of other countries to use high -precision positioning to crack down on the United States, they even deliberately increased the error of civil positioning, resulting in only 100 meters of civilian accuracy at that time, and this method was not revoked by the Clinton government until 2000.

  But for ordinary users, the accuracy of 10 meters is more embarrassing. For example, a car in a city, if you are not familiar with it, it is difficult to confirm which side you are on the road.

  Improve accuracy: It looks easy to do and difficult to do

  There are many ways to further improve accuracy: the simplest thing is to reduce the track of satellites, but in this way, in order to achieve the number of satellites that need to be launched, the number of satellites will increase sharply, which indirectly increases the deployment cost of the entire system.

  Since the accuracy of the satellite data cannot be improved, as long as other data is introduced, the most direct is to compare the GPS data with the data of the gyroscope.

  This idea has been raised for a long time, but the problem follows -huge calculations. GPS data is coordinate data, and the gyroscope is given by motion acceleration data. The complex comparison process requires a large amount of computing power.

  This time, this research team from the University of California proposed a new algorithm that can greatly reduce the budget burden, even mobile devices such as mobile phones can also be satisfied.
