Abstract EN
Autonomous Navigation Systems used in missiles and other high dynamic platforms are mostly dependent on the Global Positioning System (GPS).
GPS users face limitations in terms of missile high dynamics and signal interference.
Receiver’s tracking loops bandwidth requirements to avoid these problems are conflicting.
The paper presents a novel signal frequency and phase tracking algorithm for very high dynamic conditions, which mitigates the conflicting choice of bandwidths and reduces tracking loop measurement noise.
It exploits the flexibility of fuzzy control systems for directly generating the required Numerically Controlled Oscillator (NCO) tuning frequency using phase and frequency discriminators information and is labeled Fuzzy Frequency Phase Lock Loop (FFPLL).
Because Fuzzy Systems can be computationally demanding and an Inertial Navigation System (INS) is often onboard the vehicle, an assisted INS Doppler version has been designed and is also proposed.
Assessment of the new GPS tracking method is performed with both simulated and experimental data under jamming conditions.
The main enhancements of the proposed system consist in reduced processing time, improved tracking continuity and faster reacquisition time.
