Abstract
A mobile terminal having a function of measuring air sensitivity of global positioning system GPS and a method for measuring air sensitivity of GPS is disclosed. The mobile terminal includes: a memory for storing values of AGC PDM obtained by rotating a mobile terminal to a predetermined angle in a predetermined time period and obtaining values of AGC PDM in each predetermined angle; a computation unit for obtaining a mean value of values of AGC PDM; and a display unit for displaying the mean value.
Claims4
A method for measuring an air sensitivity of a global positioning system (GPS) in a mobile terminal, the method comprising the steps of:
- obtaining a pulse density modulation (PDM) value of an auto gain control (AGC) amplifier in the mobile terminal;
- and
- displaying the air sensitivity of the GPS on a display unit of the mobile terminal by using the PDM value.
A mobile terminal having a function to measure an air sensitivity of a global positioning system (GPS), comprising:
- an analog to digital converter for converting an analog signal to a digital signal;
- a controller for measuring a strength level of an input signal to the analog to digital converter to obtain a pulse density modulation (PDM) value according to the measured strength level of the input signal;
- an auto gain control amplifier for controlling gain thereof to maintain a predetermined strength level of the input signal to the analog to digital converter according to the obtained pulse density modulation (PDM) obtain;
- and
- a display unit for displaying an air sensitivity of the GPS by using the pulse density modulation signal.
