Latest Patents

One of Basuthakur's latest patents is an on-board three-axes attitude determination and control system. This innovative method and system control the attitude of a spacecraft during its transfer orbit using a stand-alone, three-axes attitude determination and control system. The system employs a set of on-board sensors to define two independent angular measurements, which initially identify the z-axis orientation of the spacecraft after launch vehicle separation. Additionally, a set of three-axis gyros is bias calibrated to measure the transverse rates of the spacecraft. The continuous determination of the spacecraft's three-axis attitude is achieved by integrating the gyro outputs, even when the Earth or Sun is not visible. A state estimator model is also provided to determine the spacecraft's three-axis attitude in the presence of large wobble and nutation.

Another significant patent by Basuthakur focuses on satellite thruster uncertainty estimation in transition mode. This invention addresses the estimation and compensation of fixed, but unknown uncertainties of a thruster to improve satellite attitude estimation and control. The method eliminates the need for nutation damping devices. In this system, a thruster is fired, and an attitude state is estimated using an estimator. A commanded rate change is calculated and modified using a compensating feedforward command, updated by a fixed uncertainty estimator. This modified commanded rate change is then used to incrementally adjust the thruster fire on-time until a predetermined satellite trajectory is achieved.
