Method and apparatus for spacecraft attitude control using polynomial interpolation |
| 摘要 |
A method, apparatus and system is provided for reducing an amount of information transmitted to a vehicle in order to implement attitude control of the vehicle. In accordance with the present invention, data corresponding to at least one time-varying attitude command trajectory defining an attitude of the vehicle is reduced, for example, into a vector of polynomial coefficients. The vector of polynomial coefficients then are transmitted to the vehicle, where they are used to reconstruct the at least one time-varying attitude command trajectory via a polynomial interpolation operation. |

1. A vehicle guidance system for implementing attitude control of a vehicle, comprising:
a command reduction module for generating a reduced data set corresponding to a time-varying attitude command trajectory for a vehicle, comprising
circuitry configured to receive at least one time-varying attitude commandtrajectory defining an attitude of the vehicle, andcircuitry configured to reduce the at least one time-varying attitudecommand trajectory into a vector of polynomial coefficients; and a command reconstruction module for generating data corresponding to the time-varying attitude command trajectory, comprising
circuitry configured to receive a vector of polynomial coefficients, andcircuitry configured to reconstruct at least one time-varying attitude command trajectory by utilizing the vector of polynomial coefficients and an affine transformation to perform a polynomial interpolation operation. |
