1. A sensor gimbal system comprising:
a sensor gimbal with a sensor PCB and a sensor, said sensor gimbal configurable to rotationally orient a sensitive axis of the sensor with respect to the sensor gimbal system;
a sensor motor to rotate the sensor gimbal between a first orientation and a second orientation;
an electronic circuit board, and
a flex circuit between the sensor PCB and the electronic circuit board, the flex circuit incorporating a 360° encirclement of the sensor and the sensor PCB in the first orientation,
wherein the flex circuit is received in a track in a sub-chassis engaging the sensor PCB to a sensor gimbal frame, and the flex circuit is routed to reduce signal distortion and/or kinking during rotation.
