A vehicle sensor mounting system 100 includes a tubular bridge structure 101 that in use spans across the width of the vehicle roof and attaches to existing rooftop anchor points. The bridge has a middle section for mounting a plurality of sensors to, and first and second legs to either side which are separated from the middle section by first and second bend angles. The mounting system is intended to allow camera sensors 104a-c to have full field-of-view coverage while being as close to the vehicle body as possible to reduce parallax, and not being occluded by the vehicle body or mounting system. The mounting system also allows the cameras to be co-axial with a LiDAR sensor 103 and to minimize parallax. The mounting system has a minimum natural frequency that reduces road vibrations, allowing the sensors to remain in a stable mounting position and minimizes the motion of the sensors relative to the vehicle chassis to reduce misalignment errors in the sensor data. The mounting system may include a front and rear (figure 8) assembly. The rear assembly includes a cable hub assembly coupled to the middle section that provides a single ingress/egress point for a multi-conductor sensor cable.
