Name
GALILEO PWS Rotor Attitude Right Ascension
Description

GALILEO PWS Rotor Attitude Right Ascension in EME50 (Earth Mean Equatorial equinox of 1950)

Caveats
The basic rotor coordinate system has its Z-axis aligned with the spin axis (positive in the opposite direction as the HGA) and its +Y-axis pointing outward from the spacecraft body along the magnetometer boom. X completes the right handed set. This coordinate system spins with the rotor at a period of approximately 19 seconds.
