Low-profile X-Y antenna pedestal utilizing multi-hinge points to provide angular motion for each axis

An antenna pedestal for providing angular motion comprising:

• a base, a subassembly supported on said base, pivot means between said base and said subassembly for enabling said subassembly to be angularly disposed with respect to said base about a pair of parallel axes, first linear actuator means connected between said base and said subassembly for angularly displacing said subassembly about one of said pair of axes through a first arc sector, and second linear actuator means connected between said base and said subassembly for angularly displacing said subassembly about the other of said axes through a second arc sector in a common plane with the first arc sector, said first linear actuator means causing displacement of said subassembly in a direction opposite that caused by said second linear actuator means, wherein said subassembly is a lower subassembly and wherein the pedestal further comprises an upper subassembly supported on said lower subassembly, further pivot means between said lower and upper subassemblies for enabling said upper subassembly to be angularly displaced with respect to said lower subassembly about a further pair of parallel axes, said further axes being orthogonal with respect to the axes about which the lower subassembly is disposed relative to said base, third and fourth linear actuator means connected between said upper and lower subassemblies for displacing said upper subassembly about said further axes through third and fourth arc sectors, said third and fourth arc sectors being in a plane which is orthogonal with respect to the plane of the first and second arc sectors.
