The Lomb-Scargle Periodogram is a least-square method which is useful for calculating the Fourier transform of a time history with gaps or an uneven sampling rate.

Ring Laser Gyros Acronyms: IMU – inertial measurement unit INS – inertial navigation system RLG – ring laser gyro * * * An INS uses the output from an IMU, and combines the information on acceleration and rotation with initial information about position, velocity and… Read more
There is a need in certain analysis problems to correct an acceleration signal so that its integrated velocity and double integrated displacement each oscillates about its respective zero baseline. This may require using high pass filtering, trend removal and tapering throughout the integration process. Trial-and-error… Read more
