Sampling and Control Circuit Board for an Inertial Measurement Unit

摘要

Scientists at NASA's Glenn Research Center have developed a circuit board that serves as a control and sampling interface to an inertial measurement unit (IMU). The circuit board provides sampling and communication abilities that allow the IMU to be sampled at precise intervals. The data is minimally processed onboard and returned to a separate processor for inclusion in an overall system. The circuit board allows the normal overhead associated with IMU data collection to be performed outside of the system processor, freeing up time to run intensive algorithms in parallel. This Glenn technology consists of the circuit schematic, board layout, and microcontroller firmware for the IMU sampling and control circuit board.
