Abstract

A removeable satellite antenna pointing tool can include a mounting gear releasably engageable with a pole that supports a satellite antenna. The removeable satellite antenna pointing tool can also include an azimuth gear subsystem housed in a frame and engaged with the mounting gear and a motor that drives the azimuth gear subsystem, wherein actuation of the motor causes the frame to rotate about the pole. The removeable satellite antenna pointing tool can further include a linear drive that controls an elevation of a control shaft engageable with a fixture attached to the satellite antenna. Actuation of the motor can change an azimuth of the satellite antenna and actuation of the linear drive can change an elevation of the satellite antenna.
