SARAL: Array Offset Information
Center of Mass Information:
The offset between the center of mass and the RRA optical center is X = 0.485 m, Y = 0.007 m, Z = -0.282 m in spacecraft axes (intial value).
The following coordinates are given in the ISRO S/C axis reference frame, defined as : +X is nadir-pointed, +Z opposite to cross-track (opposite to orbit angular momentum), and +Y completes the orthonormal right-handed basis. An additional 43.4 mm correction, to be subtracted from the computed range, is required to account for the RRA phase center offset.
