ABSTRACT:
The Seamless Sensory System (3S), the invention, integrates state-of-the-art sensor technology with modern software engineering practices to create seamless positioning. The invention can include the incorporation of GPS/Inertial Navigation/IR and other technologies into a handheld/man wearable/mounted system that will not be compromised in hostile environments. The invention continues accurate navigation in the absence of GPS satellite signals. The invention utilizes a “continuous calibration” Kalman Filter methodology and motion sensor(s) to maintain “GPS-like” accuracy after GPS signals are no longer available. A proprietary technology called an Ultrasonic Doppler Velocity Measurement (UVM) Sensor is the invention's ‘key component’ to create “GPS like performance” under any GPS denied condition. Additional sensors are included to complete the picture of the local environment.
