Accelerometers

Any sensor fixed to either UAV or ROV systems must be light and small and must have a low power consumption. In addition, high shocks resistance is a key element to keep the integrity of the IMU in case of crash. In terms of accuracy, the IMUs integrated on professional drones, should deliver accuracies corresponding to the Inertial Tactical Grade. Accelerometers of the Inertial Tactical Grade will have bias repeatability performances of around 1 mg.

Wind power is a sustainable power source that exploded a few decades ago. Permanent monitoring helps to avoid any unscheduled malfunction, as a lack of maintenance could cause a turbine shut down, destruction or an interruption in power production. VS1000 is a high end capacitive MEMS accelerometer, specially designed for vibration measurements from DC to medium frequencies.
