摘要： A lighter-than-air aerial platform is consisting of two or more inflatable elements (100), balloons or dirigibles, a propulsion system (400), aerodynamic lifting and flight surfaces (500) which are optionally inflatable, an on-board electronic system (303) and a release actuator that separates or deflates at least one of the inflatable elements or balloons or airships; wherein the release actuator is located at the apex of the platform, and allows the rest of the system to descend in a controlled manner to be then recovered on land or at sea; wherein at least two of the inflatable elements, balloons or dirigibles that compose it are connected together by one or more cables (200) which place them at two different flight altitudes and wherein at least one of the inflatable elements, balloons or dirigibles that generates its own vertical force due to the Archimedes effect is an antenna (600) for receiving or sending radio, light or radiation signals through the use of specific sensors or cameras.

摘要： A field-assembled satellite communications terminal has a plurality of discrete, modular aperture blocks. Each aperture block contains an electrically steered antenna aperture, and a plurality of interconnection ports for power and data communications between the plurality of aperture blocks. The plurality of interconnection ports are removably connectable by the end user in the field. The terminal further has a signal processing system for receiving, processing, and generating signals to and from the apertures. The aperture blocks are connected to each other in the field and self-configure to form an electrically-steered antenna.

摘要： The RET adjuster includes a drive assembly with a rotatable drive member operatively connected to a phase shifter assembly such that rotation of the drive member adjusts the phase shifter assembly. A first connector is coupled to the drive member where the first connector occupies a rest positon when the drive member is at rest. A drive system has a second connector occupying a rest positon when the drive system is at rest where the second connector is releasably engageable with the first connector such that actuation of the drive system rotates the drive member. A mechanical calibration system locates the second connector at the second rest position.

摘要： An antenna system for satellite applications is provide, the antenna system comprising an antenna array and a feed structure, and the antenna array is a passive antenna array configured to have a first state and a second state, the second state being a first deployed state. The feed structure is configured to provide a linearly polarized incident field for the antenna array in the first deployed state. The antenna array comprises a plurality of array elements, and the plurality of array elements forms a polarization conversion surface configured for converting the linearly polarized incident field to a reflected/transmitted circular polarized field. The antenna array is configured so that the radiation pattern of the reflected/transmitted circular polarized field corresponds to a predetermined radiation pattern and an array element geometry and an array element position of each of the plurality array elements are configured to provide the predetermined radiation pattern.

摘要： A passive antenna guard system includes an antenna guard at a location of the antenna and mounted on a common mount therewith which facilitates movement of the antenna from the path of an object responsive to the object contacting the antenna guard. The system may include a balance system which allows the antenna and antenna guard to spring back into place after the object clears the antenna guard.
