INERTIAL 2018 will have tutorials on Monday, March 26
Tutorial registration is separate from symposium registration. Tutorial Fees include access to all tutorials, coffee breaks, breakfast, and lunch on Monday.
Title: Atom Interferometer Inertial Sensors
Presenter: Prof. Kai Bongs, University of Birmingham
Title: Modeling of offset and offset drift sources in AM/FM inertial sensors
Presenter: Dr. Alessandro Tocchio, ST Microelectronics
Title: System-Level Considerations in Inertial Sensor Performance
Presenter: Prof. Michael Braasch, Ohio University
Most inertial navigation systems operate at three basic task-rates: high-speed, medium-speed and low-speed. High-speed tasks include formation and compensation of the raw delta-Vs and delta-thetas. Medium-speed tasks include attitude determination and velocity update. Low-speed tasks include position update and gravity calculation. Most inertial sensor designers concentrate their efforts in the high-speed task arena. Once the measurements have been formed and compensated, they are sent off to the systems and software engineers. This tutorial provides an overview of those ‘downstream’ tasks and focuses particularly on the long-term impact of sensor errors on inertial navigation system performance. Key error characteristics such as the Schuler, Foucault and Diurnal oscillations will be discussed. Which is more important? Gyro bias or accel bias? The answer is that it depends on the length of the mission! We will go through the details as well as highlight the criticality of additional performance metrics such as scale factor error, noise, data rate and data latency.
