Latest Patents

Purnanand Elango holds a patent titled "Eigenmotion control for near rectilinear halo orbits." This patent describes a computer-implemented method for maintaining a spacecraft near an orbit. The method involves detecting when the distance from the spacecraft to the orbit exceeds a certain threshold. In response, it linearizes the spacecraft's dynamics over a specified time horizon with respect to a high-fidelity reference trajectory. This process produces a state transition matrix (STM) that includes non-expanding eigenvectors with magnitudes less than or equal to one, as well as expanding eigenvectors with magnitudes greater than one. The method further determines a control action that alters the spacecraft's upcoming state to a linear combination of the non-expanding eigenvectors of the STM, ultimately generating a control command for the spacecraft's actuator.
