Three, non orthogonal axes achieve a complete coverage of the sky avoiding singular points. At the same time, the axes arrangement enables a perfect packaging ratio.

The upper module (payload) is an autonomous detachable unit mounted kinematically on 3 flexure joints. The unit achieves high repeatability of pointing.

Servo drive modules are also autonomous and detachable through segmented output shafts and are connected through quasi kinematic couplings.

The structure is based on a rivetted aluminum chassis, cut using Laser CNC technology.
