Abstract: The inhibition of the loop filter noise jitter is an important guarantee for precise
continuous tracking of the satellite signal in global positioning system (GPS) software receiver.
This paper uses the noise unknown but bounded assumptions, instead of the demanding
requirements of the noise statistical properties known in the traditional methods. The application
of semidefinite programming approach converts the filtering problem into a convex optimization
problem. Adopting the carrier tracking loop robust filtering algorithm to obtain the confidence
ellipsoid containing the Doppler shift, we solve the filter tracking problem for GPS receiver in the
complex and changing environment. The algorithm is validated by using the analog carrier signal
and the actual satellite signal. Results show this method effectively tracks the GPS satellite signals
and provides a new way of thinking for designing the loop filter for GPS receivers.
