Method and system for detecting interference for global positioning systems
First Claim
1. A method for detecting interference in a Global Positioning System, the method comprising the steps of:
- receiving at least one satellite signal from one or more satellites in a Global Positioning System;
measuring a noise floor value in a frequency band of the at least one satellite signal;
identifying an interference signal based on the noise floor value wherein the interference signal is determined by a comparison between the noise floor value from the at least one satellite signal and a predetermined acceptable range;
determining an interference value for the interference signal from the noise floor value wherein a level of the noise floor value corresponds to a level of interference;
wherein the comparison between the noise floor value and the predetermined acceptable range determines a corresponding interference value for the interference signal;
wherein if the noise floor value is within the predetermined acceptable range, the interference value is set at a predetermined low interference value;
wherein if the noise floor value is outside the predetermined acceptable range, the noise floor value is set at a predetermined high interference value; and
providing the interference value to at least one user for informing the user of the interference signal.
