A bootstrap power supply is used to reduce the number of DC/DC converters needed for supplying the gate drivers. The advantage of a bootstrap is the reduction of size and cost for gate driver circuitry. The disadvantages is a modulation index limit.

We design a feature-based model to estimate and predict the free height of a fixed-wing drone flying at altitudes up to 100 meters above terrain using the stereo vision principles and a one-dimensional Kalman filter. We design this using a single RGB
