文摘
- •
A novel GPS/accelerometer/anemometer integration algorithm is developed.
- •
A Vondrak filter is utilized to de-noise raw signal and isolate low-frequency noise.
- •
A least-squares based displacement reconstruction scheme is employed.
- •
An adaptive RLS filter is adopted to separate the slow-varying movements.
