The Kernel series from sensor technology producer Inertial Labs brings advanced navigation, orientation, and positioning capabilities to autonomous vehicle operations.

The Kernel line includes a range of Inertial Measurement Units (IMUs), Inertial Navigation Systems (INS), and Attitude and Heading Reference Systems (AHRS). In the field of autonomous vehicles, the precision, accuracy, and reliability of navigation systems is critical.

Understanding Inertial Systems

Kernel devices use advanced MEMS (Micro-Electro-Mechanical Systems) sensor technology, making them lightweight, energy-efficient, and compact while ensuring high accuracy and reliability. The Kernel series encompasses IMUs, INS and AHRS:

  • IMU-KERNEL-110Inertial Measurement Units (IMUs) measure three-dimensional acceleration and angular rates, providing raw data for inertial navigation systems. This data, when processed, helps determine a vehicle’s movement and position.
  • Inertial Navigation Systems (INS) combine IMU data with external sources like GPS to deliver accurate position, velocity, and orientation estimates, crucial for real-time positioning in autonomous vehicles.
  • Attitude and Heading Reference Systems (AHRS) combine accelerometers, gyroscopes, and magnetometers to offer a comprehensive three-dimensional orientation solution, vital for applications such as camera stabilization.

Importance of Kernel in Autonomous Vehicles

Accurate navigation is vital for autonomous vehicles. Even small errors can lead to collisions or incorrect decisions. Kernel products provide precision for safe and reliable autonomous operations.

Additionally, integrating various sensor inputs into a cohesive system is a challenge in autonomous vehicles. Kernel products are designed to work seamlessly with other sensors like LiDAR, cameras, and radar, offering a comprehensive solution.

Autonomous vehicles also face diverse conditions, from temperature changes to vibrations. Kernel products are built to withstand such conditions, ensuring consistent performance.

Applications of Kernel in Autonomous Vehicles

GPS signals can be weak or unavailable in areas like tunnels or urban canyons. By utilizing its inertial data, Kernel INS ensures accurate navigation in such scenarios. Kernel AHRS is also crucial for camera systems used in vehicle perception, or stabilizing the vehicle’s movement on challenging terrains.

Combining data from Kernel products with other sensors helps create a holistic view of the surroundings, essential for obstacle detection, path planning, and decision-making in autonomous vehicles.

If primary navigation systems fail, Kernel products can serve as a backup, ensuring continuous navigation.
