About
This product is a six-degree-of-freedom mechanism designed for high precision transfer and rotation of a target object in 3 linear and 3 angular directions within its intrinsic frame of reference, across defined working paths. It serves as a component of a testbed used to test antenna radio engineering performance in ground conditions. The mechanism provides rotation around the frame of reference axes within a range of ±7°, with an angular rotation increment of 25” and an angular rotation error of ±30”. Linear motion along the OX and OY axes of the frame of reference has a range of ±100 mm, while linear motion along the vertical OZ axis has a range of ±25 mm; the linear motion increment is 10 μm with a linear motion error of ±0.01 mm. The device has overall dimensions of 530 mm in diameter and 673 mm in height, with a mechanism mass of 21 kg. It was released in 2012, has a guaranteed service life of 10 years, and an estimated production/delivery time of 4 months. The product has not undergone flight qualification, but it can be adapted to customer requirements, and development of a space version based on this solution is available.
