In this paper, a spaceborne SAR interferometry system operates on the strapdown inertial navigation mechanism, which is based on maximum likelihood phase estimation method. It has been shown using simulated data that phase estimation of cross-track multi-baseline synthetic aperture radar (SAR) interferometric data is most efficiently achieved through a maximum likelihood phase estimation method...

We consider a left-invariant dynamics on an arbitrary Lie group. We show that it is possible, when the output map is compatible with right multiplications, to build non-linear observers such that the error equation is autonomous. The theory is illustrated by an inertial navigation example. Index Terms Lie group, symmetries, invariance, nonlinear asymptotic observers, inertial navigation.

This paper considers a fault accommodation problem for inertial navigation systems (INS) that have redundant inertial sensors such as gyroscopes and accelerometers. It is wellknown that the more sensors are used, the smaller the navigation error of INS is, which means that the error covariance of the position estimate becomes less. Thus, when it is decided that double faults occur in the inerti...

This paper provides an overview of the primary strapdown inertial system computational elements and their interrelationship. Using an aircraft type strapdown inertial navigation system as a representative example, the paper provides differential equations for attitude, velocity, position determination, associated integral solution functions, and representative algorithms for system computer imp...

This paper considers the optimal sensor configuration for inertial navigation systems which have redundant inertial sensors such as gyroscopes and accelerometers. We suggest a method to determine the optimal sensor configuration which considers both the navigation and FDI performance. Monte Carlo simulations are performed to show the performance of the suggested optimal sensor configuration met...

In this paper, a simulation is used to examine the sensitivity of enhanced laser-guided bombs to errors in the navigation system of the delivery aircraft. Three possible weapon configurations are considered: a laser-guided bomb with an autonomous inertial navigation system, a laserguided bomb with a loosely-coupled inertial navigation system and global positioning system, and a standard laser-g...
