BACKGROUND

Sensors, such as imaging sensors, can be mounted to mobile vehicles, such as aircraft, land vehicles, and watercraft using a payload system mount rotatably coupled to the vehicle. The payload system mount with its rotatable coupling can include at least two rotating joints. For example, a first rotating joint can allow azimuth rotation of the payload system mount while a second rotating joint coupled to the first rotating joint can allow elevational rotation of the payload system mount. A crossbar system can be coupled to the payload system mount and can support a sensor assembly (e.g., an imaging assembly or system) in isolation. The sensor assembly can be mounted at a central location of the crossbar system and a first and second end of the crossbar system can be coupled to the payload system mount. Thus, the first rotating joint can be configured to facilitate azimuth rotation of the sensor assembly, and the second rotating joint can be configured to facilitate elevational rotation of the sensor assembly.

The crossbar system is configured to transmit motion of the payload system mount to the sensor assembly. However, it is not desirable to transmit all motion to the sensor assembly. For example, sensors can be sensitive to vibration and sudden acceleration (e.g., due to shock or other loads) and can experience a loss of resolution when subjected to these. For example, vehicles experience accelerations and vibrations during operation that can be detrimental to the functioning of the sensor. These accelerations and vibrations, if not isolated and damped, can be transmitted from the vehicle through the payload mount system to the sensor assembly and the sensor payload.
