Quad-segment polynomial trajectory guidance for impact-time control of precision-munition strike

Year: 2016

Type: article

Abstract: Accurate calculation of time to go until impact is an essential component in coordinating multiple precision-guided munitions for a simultaneous strike. Conventional means for calculating time to go contain potential errors, due in part to the trajectory curvatures, and may fall short on the accuracy required to achieve a desired impact time, especially if velocity changes rapidly due to atmospheric drag and gravity. A closed-loop guidance law will be presented in which an optimized, piecewise continuous, and smooth family of polynomial trajectories is parameterized in terms of downrange distance and has a closed-form solution of arc length for improved calculation of time to go.
