Microsoft to develop cloud GPS technology can theoretically 1.5 of the time

According to foreign media reports, the Microsoft Research Laboratory is developing a GPS technology, will be redundant data uploaded to the cloud to solve the equipment's high energy consumption problems. The technology developed by Microsoft is known as Cloud-offload GPS (CO-GPS), according to the mhttp://www.aliyun.com/zixun/aggregation/10958.html ">it Technology Review". is currently being tested on a new mobile sensor platform Cleo.

GPS sensors in smartphones are often the most-eaten part of the device. According to the data provided by the research lab, GPS sensors in smartphones are currently running for up to 6 hours. And if Co-gps technology is activated, the cell phone can theoretically stay 1.5 of the time.

In general, to correct the user's position, the GPS sensor needs to run 30 seconds or more to get the necessary information from the orbiting satellite, including a lot of signal processing work. Now the CO-GPS technology developed by researchers can get raw repair data in milliseconds. In addition, this cloud-powered technology can also use public information, such as satellite trajectories and earth elevation databases, to reduce the power consumption of equipment. For example, under the current technical conditions, if you want to get a smartphone for a raw GPS repair will need to consume 1 joules of energy, and if the use of CO-GPS technology, the need for the original 0.04% of the energy, a full reduction of 99.96%.

Researchers at the Microsoft Research Institute believe that the emergence of this new technology will lead to a new service based on GPS continuous logging, such as creating an up-to-date noise pollution database.
