ABSTRACT:
Embodiments of the portable antenna positioner described provide a lightweight, collapsible and rugged antenna positioner for use in receiving low earth orbit, geostationary and geosynchronous satellite transmissions. By collapsing the antenna positioner, it may be readily carried by one person or shipped in a compact container. The antenna positioner may be used in remote locations with simple or automated setup and orientation. In order to operate the apparatus, azimuth is adjusted by rotating an antenna in relation to a positioner base and elevation is adjusted by rotating an elevation motor coupled with the antenna. The apparatus may update ephemeris data via satellite, may comprise a built-in receiver and may couple with a second positioner base comprising cryptographic, router or power functionality. The apparatus may comprise storage devices such as a hard drive or flash disk for storing data to and from at least one satellite.
