Extracting Dynamics Matrix of Alignment Process for a Gimbaled Inertial Navigation System Using Heuristic Dynamic Programming Method

In this paper, with the aim of estimating internal dynamics matrix of a gimbaled Inertial Navigation system (as a discrete Linear system), the discretetime Hamilton-Jacobi-Bellman (HJB) equation for optimal control has been extracted. Heuristic Dynamic Programming algorithm (HDP) for solving equation has been presented and then a neural network approximation for cost function and control input ...

Inertial Navigation by Interpolating the Flight Path of Moving Objects Based on Acceleration or Velocity Measurements

This paper presents solutions to two cases of the inertial navigation problem, which is the problem of estimating the flight path of a moving object based on partial information. In the first case considered, only acceleration data and in the second case considered only velocity data is assumed to be available. In both cases simple and fast recurrence equationbased algorithms are provided that ...

Vision-Aided Inertial Navigation for Flight Control

Many onboard navigation systems use the Global Positioning System to bound the errors that result from integrating inertial sensors over time. Global Positioning System information, however, is not always accessible since it relies on external satellite signals. To this end, a vision sensor is explored as an alternative for inertial navigation in the context of an Extended Kalman Filter used in...
