The DSX and Arase spacecraft and their fixed coordinate frames. A The DSX spacecraft consists of a payload module affixed to one side of an ESPA (Evolved Expendable Launch Vehicle Secondary Payload Adapter) bus and an avionics module on the opposite face. The VLF antenna has two 40 m booms used as an effective 80 m dipole along the spacecraft Y-axis. During transmission, DSX maintained an orientation relative to the geomagnetic field B as shown (with + Y perpendicular to B). B The Arase spacecraft has a full suite of particle and field instruments for observing the inner magnetosphere. While DSX is 3-axis stabilized, Arase spins about its Z-axis as indicated in Spinning-satellite Geometry Inertia (SGI) coordinates
