We have a BlueROV for research purpose. We have installed a multibeam sonar Oculus M750d and a new IMU VectorNav VN100. As discussed here, we met series crosstalk between two twisted pairs. So right now we use two Fathom-X boards and only one twisted pair. However, when we turn on sonar, the IMU received on the laptop drops from the original 200Hz to 160Hz. The bandwidth used by the sonar is 2MB/s, which is much lower than the maximum 10MB/s.
We’d like to keep a higher sonar image rate, meanwhile not to lose any IMU measurement. Do you have any idea or suggestion?
