Fuzzy systems, Global Positioning System, Phase-locked loops, Parametrons, and Artificial satellites in navigation
The article offers information on the performance and benefits of a fuzzy tracking system. It mentions that fuzzy systems are designed to test an innovative frequency lock loop (FLL) which allows reducing the phase-lock loop (PLL) bandwidth. It informs that PLL, FLL, and fuzzy system are useful for global positioning system (GPS). It highlights how fuzzy system is used to tune the numerically controlled oscillator (NCO) and ensure accurate and robust signal tracking.
