GPS + inertial + camera + LiDAR + baro-altimeter = a very precise measurement, right? Not when the respective sensor output timings lack proper synchronization. Only when each piece of data carries an accurate timetag can they together enable optimal performance in multi-sensor fusion systems.

The MEMS-based inertial measurement unit (IMU) represents the single biggest positioning and navigation advance of the last 20 years. That assertion is made during the first of three panels in the webinar “Inertial Technology for Robotics, UAVs and other Applications,” freely available on May 6. The 1.5 hour presentation examines how this breakthrough plays in the fields of autonomy, high dynamics and challenging environments, including on the frontiers of space.
Three experts takes a close-up look at contemporary and emerging inertial sensor technologies and applications, from the laboratory to the factory to the field. Register here to attend. The webinar is sponsored by Sensonor.
MEMS (micro-electromechanical sensors) make possible a miniaturization of size, weight, power requirements and cost never thought achievable before. When MEMS inertial navigation pairs with GPS for navigation, the key factor is the error budget of each sensor and how that plays into the accuracy of the solution. Attendees will learn how the new inertial sensors’ reduced error budgets translate into higher system performance.
The presentation begins with the current state of the inertial art, delivered by a recognized expert. The second speaker describes a high-accuracy tactical-grade inertial measurement unit (IMU) with increased accelerometer performance to support demanding guidance and navigation applications.
This knowledge is taken to the field to examine the IMU’s role in successful satellite launch missions during the third panel. The attitude determination and control system (ADCS) rises to the challenge of an extremely demanding environments and set of requirements. A satellite moving at a speed of 7,500 meters/second over ground requires precise maneuvering, stabilization and point in order to obtain imagery at 1-meter resolution.
Questions from the audience are actively encouraged and will be addressed by the three speakers in the final portion of the webinar.
