Title: Andrew Cartmell and GNSS Interference Mitigation
Introduction
Andrew Cartmell is an inventor associated with Trimble Inc. in Santa Clara, California. His patent work addresses interference mitigation in Global Navigation Satellite System (GNSS) receivers.
Latest Patents
Cartmell is credited with 1 patent: “Baseband Architecture for GNSS Jamming Mitigation.” The invention describes a baseband circuit and operating method designed to reduce jamming and other interference in a GNSS receiver. It combines time-domain interference mitigation (TDIM), which can use notch filters, with frequency-domain interference mitigation (FDIM) across multiple radio-frequency paths. A processor analyzes received satellite-signal samples using a direct Fourier transform and uses the results to adjust the mitigation circuits. Its control parameters can include notch-filter coefficients for rejecting multiple narrow-band interferers.
Career Highlights
Cartmell’s listed patent reflects work on signal-processing techniques for improving GNSS receiver resilience. The invention’s approach coordinates time- and frequency-domain filtering to address interference.
Collaborations
Cartmell is associated with Trimble Inc. His listed coworkers include David S. De Lorenzo and William Lentz.
Conclusion
Andrew Cartmell’s patent focuses on a practical baseband architecture for mitigating jamming and other interference in GNSS receivers.
