The Inertial Labs INS-D-OEM inertial navigation system features temperature calibrated and precisely aligned tri-axis MEMS accelerometers and gyroscopes, and ensures accurate time synchronization amongst independent data packets to result in a guaranteed high-performing system-level solution. The high-quality components are paired with a robust onboard Kalman filter, resulting in trajectories with heading accuracies of 0.03 degrees and pitch & roll accuracy of 0.006 degrees. These values directly affect point cloud accuracy, which is why the team at Rock Robotic chose the INS-D-OEM to be the solution for the R2A and can confidently specify a system accuracy of 5 centimeters or less.
The development of drone LiDAR payloads has had a substantial effect on industrial inspection applications such as powerline inspection. Powerline inspection with ground inspection teams is a labour-intensive, time consuming, and potentially dangerous process, and payloads such as the R2A can transform the process into an accurate, cost-effective, and time-efficient alternative to in-person ground-based surveillance. The multiple return method of scanning with the Livox Avia and excellent position and orientation accuracy from the INS-D-OEM ensure that the R2A provides a highly dense and accurate point cloud for powerline classification.
Harrison Knoll, CEO and Co-Founder of ROCK Robotic, commented: “The Inertial Labs team has a deep understanding of the whole navigation technology ecosystem; this has made their products offer world class performance and maintain easy integration and interoperability with GNSS receivers and onboard computer systems. Now when I think about best-in-class accuracy, I think Inertial Labs.”
Jamie Marraccini, Inertial Labs CEO and Founder, said: “It really has been a great marriage of skillsets. With ROCK Robotic’s vast knowledge of the drone-based surveying market and industry and our experience in the inertial navigation field, customers can trust that ROCK LiDAR payloads have been designed by a collective team of professional and experienced engineers with the customer’s best interest in mind.”
