JAVA ASTRODYNAMICS TOOLKIT (JAT)

摘要

The Java Astrodynamics Toolkit (JAT) is an open source software library of reusable software components for space mission design, trajectory optimization, and simulation of spacecraft navigation, attitude determination and control systems. The current capabilities of JAT include orbit propagation, coordinate and time system transformations, orbit determination using ground tracking or GPS measurements, maneuver planning, spacecraft attitude simulation, and 2-D and 3-D orbit and attitude visualization. JAT is distributed under the GNU General Public License. This paper describes the current features of JAT and presents the rationale for choosing to write it in Java and to make it open source.
