Abstract
  In this study, Adaptive Network-Based Fuzzy Inference System (ANFIS) is presented with sensor data fusion approach to estimate satellite attitude. The active sensors are sun and earth sensors. Satellite attitude dynamic, including attitude quaternion and angular velocities are estimated simultaneously ...  Read More

Practical Evaluation of EKF1 and UKF2 Filters for Terrain Aided Navigation

A. Moghtadaei Rad

Volume 9, Issue 1 , March 2012

Abstract
  This article would study batch and recursive methods that used in terrain navigation systems. Terrain navigation has a lot ofdisadvantages and so researchers have been studied on different method of aided navigation for many years. Therefore, more types of aided navigation systems were introduced with ...  Read More
