  • Method for measuring GPS air sensitivity and mobile terminal having function of measuring GPS air sensitivity
    Patent number: 7151487
    Abstract: A method for measuring an air sensitivity of a global positioning system (GPS) signal in a mobile terminal. A GPS signal value is obtained in the mobile terminal. The air sensitivity of the GPS signal value based on a reference GPS signal value is stored in a memory of the mobile terminal, and the air sensitivity of the GPS signal using the analyzed result is displayed on the display unit. A mobile terminal including a controller for obtaining a global positioning system (GPS) signal value is also provided. The terminal also includes a display unit for displaying an air sensitivity of the GPS by using the GPS signal value, and a memory for storing a reference GPS signal value. The controller analyzes the GPS signal value based on the reference GPS signal value, and the display unit displays the air sensitivity of the GPS using the analyzed result.
