Systems and methods for GNSS processing during interference suppression

A method, comprising:

• receiving an incoming signal, the incoming signal including a radio frequency (RF) satellite signal from a satellite vehicle;
• generating a calibration signal;
• applying the calibration signal to the incoming signal to generate a calibrated incoming signal;
• executing an interference suppression algorithm on the calibrated incoming signal to generate a suppressed calibrated incoming signal;
• executing a first tracking channel using the suppressed calibrated incoming signal to generate a suppressed calibrated pseudorange parameter;
• comparing the suppressed calibrated pseudorange parameter to a predetermined calibrated pseudorange parameter to determine an interference suppression error;
• executing the interference suppression algorithm on the incoming signal to generate a suppressed incoming signal;
• executing a second tracking channel corresponding to the satellite vehicle using the suppressed incoming signal to generate a satellite pseudorange parameter;
• modifying the satellite pseudorange parameter using the interference suppression error;
• and
• outputting a location of a receiver device based on the modified satellite pseudorange parameter.

An airborne platform, comprising:

• a satellite receiver associated with an antenna configured to receive an incoming signal, the incoming signal including a radio frequency (RF) satellite signal from a satellite vehicle, the satellite receiver including a processing circuit configured to:
• generate a calibration signal;
• apply the calibration signal to the incoming signal to generate a calibrated incoming signal;
• execute an interference suppression algorithm on the calibrated incoming signal to generate a suppressed calibrated incoming signal;
• execute a first tracking channel using the suppressed calibrated incoming signal to generate a suppressed calibrated pseudorange parameter;
• compare the suppressed calibrated pseudorange parameter to a predetermined calibrated pseudorange parameter to determine an interference suppression error;
• execute the interference suppression algorithm on the incoming signal to generate a suppressed incoming signal;
• execute a second tracking channel corresponding to the satellite vehicle using the suppressed incoming to generate a satellite pseudorange parameter;
• modify the satellite pseudorange parameter using the interference suppression error;
• and
• output a location of the satellite receiver based on the modified satellite pseudorange parameter.
