The system, by effectively integrating INS/DGPS, is not only with highpositioningaccuracy and working reliability, but also outputs real time and continuous information.
Simulation results show that the fuzzy controller with self-adjusting parameters makes the system have rapid dynamic response speed and highpositioningaccuracy.
As for the high precision positioning of underwater targets, the GPS sonobuoy technique has two bottlenecks: high precision system clock synchronization and high accuracy time delay estimation.
