Principal Axes (PA) System. The principal axes frame is aligned with the principal inertia axes, with the Z axis along the maximum inertia and the X axis along the minimum inertia. This is sometimes referred to as the axis of figure frame. The PA frame is developed in conjunction with the development of the ephemerides for the Moon.

Feb 14, 2023 · This topic provides an overview of the reference frames (coordinate systems) and the FK5 IAU76 Theory for central bodies in STK. For central bodies defined using the Vector Geometry tool, see Vector Geometry Tool Reference Frames .
International Terrestrial Reference Frames (ITRFs) are realizations of the fixed frame of the Earth that are updated periodically by the International Earth Rotation and Reference Systems Service (IERS) to account for plate tectonics and other geophysical phenomena.
Jun 20, 2024 · With Systems Tool Kit (STK), you model complex systems inside a realistic and time-dynamic three-dimensional simulation that includes high-resolution terrain, imagery, RF environments, and more.
Systems Tool Kit (STK) is an indispensable digital mission engineering application for the aerospace, defense, telecommunications, and other industries. It features an accurate, physics-based modeling environment to analyze platforms and payloads in a realistic mission context.
Systems Tool Kit (formerly Satellite Tool Kit ), often referred to by its initials STK, is a multi-physics software application from Analytical Graphics, Inc. (an Ansys company) that enables engineers and scientists to perform complex analyses of ground, sea, air, and space platforms, and to share results in one integrated ...
You also need to ensure that your pole wander/motion and UTC-UT1 constants match between STK and your Matlab code. Mismatch in polar motion will easily lead to a few hundred meter error. The STK Help has a pretty good overview of "Central Body Reference Frames" which can help you.
