Low latency between physical motion and output is critical in this type of application, additionally is high bandwidth and precise synchronization.
The Ellipse sensors show a total latency of less than 3 ms between motion and output. Furthermore, these units are carefully designed with signal conditioning and FIR filtering to provide very low latency and high bandwidth while protecting the measurement from vibrations.
Finally, we also pay attention to the gyroscopes and accelerometers synchronization to achieve the best accuracy.

MASC UAV MASC is a small UAV developed for atmospheric boundary layer research. The IG-500N has been chosen to record the UAV position, ground speed, and attitude angles. Wind speed and direction can be accurately calculated by taking into account the airflow. In-flight wind computation might be tricky because airspeed and incident angles, measured by … Continued
The Mars Rover Project The McGill Robotics team designed the robot to participate in two international competitions which required every team to operate their rover, from a hidden control center, in a Mars-like desert environment through various runs to accomplish complex tasks. These tasks involved traversing rough terrains, carrying payload to remote locations, servicing a … Continued
Tips
Low latency between a physical motion and output is very important in this type of application, additionally to a high bandwidth, and a precise synchronisation. Ellipse sensors show a total latency of less than 3 ms between motion and output, are carefully designed with signal conditionning and fir filtering to provide very low latency and a high bandwidth while protecting the measurement from vibrations. Finally, we also pay attention to gyroscopes to accelerometers synchronization and timing to achieve the best accuracy.
SBG inertial sensors are highly resistant to shock and vibration. They also embed specific algorithms to filter vibration. When choosing the right inertial sensor, note that the A3 accelerometer (16g) is the right option for harsh environments.
SBG Ellipse IMU delivers a 1,000 Hz raw data with very low latency. Data are highly reliable as every sensor is extensively calibrated in temperature, from -40 to +85°C.
The Inertial Measurement Unit (IMU) outputs gyroscopes, accelerometers, and magnetometers raw data. The Attitude and Heading Reference System (AHRS) embeds an Extended Kalman Filter (EKF) to deliver orientation data, and the Inertial Navigation System (INS) additionally embeds a GNSS receiver for a filtered position in real-time.
