Systems and methods for monitoring broadband radio frequency interference

A method for monitoring broadband radio frequency interference, the method comprising:

• measuring a carrier to noise value for at least one satellite through at least one global navigation satellite system receiver;
• calculating a smoothed carrier to noise value, wherein the smoothed carrier to noise value is calculated based on measurements from the at least one global navigation satellite system receiver during a first time period;
• calculating a jammer power to noise power value;
• calculating an average jammer power to noise power value, based on the jammer power to noise power value;
• calculating an instantaneous carrier to noise value based on the average jammer power to noise power value and the smoothed carrier to noise value;
• determining whether to exclude signals received from the at least one satellite from calculations of global positioning data based on a comparison of the instantaneous carrier to noise value to an exclusion threshold;
• and
• when the signals received from the at least one satellite are excluded, monitoring the signals received from the at least one satellite for readmittance to the calculation of global positioning data.

A program product for monitoring broadband radio frequency interference, the program product comprising a plurality of instructions tangibly stored on a non-transitory storage medium, the instructions operable when executed, to cause a processing unit to:

• calculate a set of statistics based on at least one received signal associated with at least one receiver and at least one satellite, wherein the set of statistics include a smoothed carrier to noise value and an instantaneous carrier to noise value for the at least one received signal;
• detect broadband radio frequency interference by comparing the smoothed carrier to noise value to the present carrier to noise value, and computing a jammer power to noise power value based on an average difference between the smoothed carrier to noise value and a present carrier to noise value, and then computing an instantaneous carrier to noise value from the smoothed carrier to noise value and a jammer power to noise power value, wherein the at least one received signal is excluded from calculation of global positioning data based on the comparison of the instantaneous carrier to noise value to an exclusion threshold;
• and
• when the at least one received signal is excluded, monitor the at least one received signal for readmittance to the calculation of global positioning data.
