Abstract
  For precise locating, Differentials Global Positioning System requires prediction of differential corrections for the future times. The system is comprised of both fixed and mobile stations. If the satellites of the two stations are exactly the same, the sources of errors will be close to each other ...  Read More

Verification of a Low Cost Method for Accelerometers Calibration with a Two-Axis Table

Mohsen Bahrami; Behzad Parsi

Volume 7, Issue 4 , January 2015, , Pages 73-79

Abstract
  In this paper a low cost calibration method which can calibrate with measuring the sensor displacement is suggested. To verify this calibration method a two-axis table, which is expensive, with artificial neural network (ANN) for mapping non-linear relationships between the inputs and outputs is used. ...  Read More
