Gyroscope Drift Error Analysis in the Position-Independent Navigation Algorithm of a stable platform Inertial System

This paper deals with analyzing gyroscope drift error in the position-independent navigation algorithm of a stable platform inertial system. Most of the stable platform navigation algorithms proposed in the literature have drawbacks of estimating position rates for alignment commands. Not only the estimating position rates are the basic source of position errors, but they also make the alignmen...

a study on insurer solvency by panel data model: the case of iranian insurance market

the aim of this thesis is an approach for assessing insurer’s solvency for iranian insurance companies. we use of economic data with both time series and cross-sectional variation, thus by using the panel data model will survey the insurer solvency.

An Innovative Navigation Algorithm Using a System of Fixed Pseudolites

An innovative navigation algorithm, which utilizes a system of fixed pseudolites is derived, analyzed, discussed, and simulated in this paper. Although this algorithm uses the same Doppler measurements as a conventional least square algorithm LSA (which produces user velocity and ION NTM 2001, 22-24 January 2001, Long Beach, CA 61 user clock drift) or Kalman based filter (which obtains user pos...
