Integral dual gimbal device
A device comprising a single element which includes two integrally connected gimbals for use in satellite communications, wherein the device is characterized in being capable of performing two rotational movements around two axes that are orthogonal to each other.
1. A detachable sealed box for use in conjunction with an antenna structure to enable satellite/HAP communications, wherein said detachable sealed box comprises:
two motors, each associated with gimbals comprised in said antenna structure, wherein said two gimbals are substantially perpendicular to each other, and wherein each of said two motors is configured to provide rotational movements to the gimbal associated therewith;
RF elements;
Printed Circuit Boards (PCBs):
an electrical connector; and
a controller; and
wherein said detachable sealed box is configured to be mounted onto said antenna structure and be connected thereto by a main element configured to mechanically connect said detachable sealed box to the antenna structure;
wherein the two gimbals are integrally connected gimbals having a pivoted support which is common to both axes; and
wherein upon connecting said detachable sealed box to said antenna structure, said combination is configured to perform two rotational independent movements around two axes that are orthogonal to each other.
2. The device of claim 1 , further adapted to perform a rotational movement around at least one of the two orthogonal axes of less than a 360° of a rotational movement, said device comprising one or more torsion springs configured to eliminate possible backlashes in a gear of a motor operative to enable the less than a 360° rotational movement around the at least one of the two orthogonal axes.
3. The device of claim 1 , wherein the rotational movements are of up to ±45° in both vertical and horizontal axes.
