A positioner (or gimbal assembly) for a compact antenna assembly is disclosed. The positioner provides accurate pointing of the antenna assembly (typically a narrow beam radio frequency (RF) radiating assembly) mounted on a rapidly moving platform. The positioner is comprised of a first, second, and third axis assemblies which support the antenna assembly and allow rotation of the antenna assembly about first, second, and third axis. The axis assemblies are arranged so the first, second and third axis are non-orthogonal and intersect at the approximate geometric center of the antenna assembly allowing continuous and independent rotation of the antenna assembly about each axis within a confined volume.
