Using Evolutionary Computation on GPS Position Correction

Blog Article

More and more devices are equipped with global positioning system (GPS).However, those handheld devices with consumer-grade GPS receivers usually here have low accuracy in positioning.A position correction algorithm is therefore useful in this case.In this paper, we proposed an evolutionary computation based technique to generate a correction function by two GPS receivers and a known reference location.Locating one GPS receiver on the known location and combining its longitude and latitude information and exact poisoning information, the proposed technique is capable of evolving a correction function by such.

The proposed technique can be implemented and executed on handheld devices without click here hardware reconfiguration.Experiments are conducted to demonstrate performance of the proposed technique.Positioning error could be significantly reduced from the order of 10 m to the order of 1 m.
