Abstract: Provided are a method and device for determining a non-line of sight (NLOS) state around a GPS receiver. The method may include collecting, from at least one satellite, satellite information including a direction angle, a signal to noise (SNR), and an altitude, selecting a satellite of which the NLOS state is to be determined based on an altitude value of the collected satellite information, and determining whether the selected satellite is in the NLOS state with respect to a direction to the satellite based on the SNR and direction angle included in the satellite information of the selected satellite. According to the present invention, by reducing a location calculation error that occurs due to a distance measurement error when a location is measured, a more precise result of location measurement can be obtained.
