Volume 15, Issue 2 , October 2022, , Pages 47-60

https://doi.org/10.22034/jast.2022.306926.1099

Abstract
  Inertial navigation amplifies the noise of the input sensors over time due to the presence of an integrator in the output path to determine the position and attitude of the object. This system has high bandwidth and good short-term accuracy. On the other hand, GPS navigation has low bandwidth, low noise ...  Read More

Ali Khavari; S. Mohammad Reza Moosavi; Amir Tabatabaee; Hadi Shahriyar Shahhosseini

Volume 12, Issue 2 , October 2019, , Pages 11-18

Abstract
  Abstract: Urban canyon is categorized as hard environment for positioning of a dynamic vehicle due to low number and also bad configuration of in-view satellites. In this paper, a tuning procedure is proposed to adjust the important factors in Kalman Filter (KF) using Genetic Algorithm (GA). The authors ...  Read More

Real Time Calibration of Strap-down Three-Axis-Magnetometer for Attitude Estimation

M. Kiani

Volume 10, Issue 2 , September 2013

Abstract
  Three-axis-magnetometers (TAMs) are widely utilized as a key component of attitude determination subsystems and as such are considered the corner stone of navigation for low Earth orbiting (LEO) space systems. Precise geomagnetic-based navigation demands accurate calibration of the magnetometers. In ...  Read More
