Claim:
1. A three-axes pedestal for stabilizing the pointing of a mobile tracking antenna, said pedestal comprising: a base support with an azimuth axis support having a centerline defining a first axis or azimuth axis; a first frame being rotatably mounted on the azimuth axis support to rotate about the first axis, said first frame holding at least part of a first horizontal linear bearing assembly; a second frame with a lower frame part slidably interconnected to the first frame via the first horizontal linear bearing assembly, said first linear bearing assembly including dampers or suspension members for dampening linear slide movement of the second frame along the first linear bearing assembly and thereby for dampening the relative movement of the second frame to the first frame; a third frame interconnected to an upper part of the second frame, said third frame holding a cross-elevation axis support with a centerline defining a second axis or cross-elevation axis; a fourth frame being rotatably mounted on the cross-elevation axis support of the third frame to rotate about the second axis, said fourth frame holding an elevation axis support with a centerline defining a third axis or elevation axis; and a fifth frame supporting the tracking antenna and being rotatably mounted on the elevation axis support of the fourth frame to rotate about the third axis; wherein the upper part of the second frame holds a second linear bearing assembly being a horizontal linear bearing assembly, and wherein the third frame is interconnected to the second frame via the second linear bearing assembly, with the second linear bearing assembly providing a direction of linear oscillation for the third frame, said direction of linear oscillation of the third frame being substantially horizontal relative to the second frame and substantially perpendicular to the first axis.
