    Abstract: A crossbar assembly for facilitating isolation of a sensor assembly from vibration of a payload mounting system on a vehicle comprises an outer crossbar segment, an inner crossbar segment, and an isolator. The outer crossbar segment comprises a payload mount interface operable to mount to a payload mount, and an outer isolator interface operable to mount to an isolator. The inner crossbar segment comprises a structure interface to mount to a structure, and an inner isolator interface operable to mount to the isolator. The isolator can be supported by the outer and inner crossbar segments. The isolator comprises an elastomeric component operable to elastically deform in response to relative movement between the outer and inner crossbar segments. The isolator operates to partially decouple the outer crossbar segment from the inner crossbar segment and dampen vibrations propagating between the outer and inner crossbar segments.

    Abstract: An optical assembly includes a primary mirror, a secondary mirror, and an optical steering system configured to support and position the primary mirror and the secondary mirror. The optical steering system includes a base and a yoke rotatably coupled to the base. The yoke is configured to support the primary mirror to rotate the primary mirror about a first axis and to support a secondary mirror to rotate the secondary mirror about a second axis. The yoke further is configured to rotate the primary and secondary mirror about a third axis. The secondary mirror is configured to move from a stowed position in which the optical assembly is positioned to receive an image from a field of view to a deployed position in which the optical assembly is positioned to receive an image from a field of regard.

    Abstract: A crossbar system for facilitating isolation of a sensor assembly from external vibrations of a support structure. The crossbar system comprises first and second crossbar assemblies and a payload mount, Each of the first and second crossbar assemblies comprises a crossbar segment and a slip plate damper. Each crossbar segment comprises a payload mount interface at a first end of the crossbar assembly and a first support structure interface at a second end of the crossbar assembly. Each slip plate damper is disposed about the crossbar segment and is slidably coupled to the crossbar segment to constrain movement in two lateral degrees of freedom and to facilitate movement in a longitudinal degree of freedom, Each slip plate damper comprises a second support structure interface at the second end of the crossbar assembly. The payload mount is coupled to the payload mount interfaces of the first and second crossbar assemblies.
