| ATS-VDHCoordinateSystem | The other ATS coordinate system is ATS VDH. In this system H is chosen parallel to the Earth's spin axis. V is the local vertical. Since ATS-1 is in the Earth's equatorial plane, V is perpendicular to H. Finally, D, completes the right-handed set (D = H x V) and is azimuthal, eastwards in the equatorial plane. | Ryan McGranaghan | 2023.04.16 |
| ATS-XYZCoordinateSystem | The ATS XYZ system is the coordinate system in which the ATS magnetometer data are originally obtained. The Z-axis is parallel to the Earth's rotation axis. Thus, it is parallel to the Z-axis of the g eographic, and GEI systems. However, the Y-axis is chosen perpendicular to the Earth-Sun line towards dusk. The X-axis completes a right handed orthogonal set. Thus the X-Y plane is the Earth's rotational equator with X in the noon meridian. | Ryan McGranaghan | 2023.04.16 |
