+This service is used to control the positioning of the [wiki:Hardware/SubSystems/Sivers Sivers 60 GHz] antenna arrays mounted on the XY-tables in [wiki:Architecture/Domains/cosmos_sb1 COSMOS Sandbox 1]. The XY tables allow for independent movement of each antenna array in the horizontal plane within a 1.3m x 1.3m area, as well as rotating the arrays +/-45° about their vertical axis.

+Useful usage notes:
+* X,Y movement is limited within a 1.3m x 1.3m area.
+* The antenna arrays may be rotated +/-45° about their vertical axis.
+* The centers of the tables are approximately 20m apart.
+* The coordinate systems of the tables are 180° rotated from each other (xytable1 has 0,0 in the "lower-right", while xytable2 has 0,0 in the "upper-left").
+* For the arrays to be aligned "head on", the x-coordinate must follow this pattern:
+ * When xytable1 at x=0, then xytable2 at x=1300
+ * When xytable1 at x=650, then xytable2 at x=650
+ * When xytable1 at x=1300, then xytable2 at x=0
+* Angles are defined relative to each array.
+ * Angles toward the "positive direction" are clockwise when viewed from overhead.
+ * Angles toward the "negative direction" are counter-clockwise when viewed from overhead.
+* If the antennas are aligned on the x-axis, then an angle of 0° will ensure the antennas are facing each other.
