Relative Position Error Analysis for Mars Probes

Error Scaling in Position Estimation from Noisy Relative Pose Measurements

We examine how fast the estimation error grows with time when a mobile robot/vehicle estimates its location from relative pose measurements without global position or orientation sensors. We show that both bias and variance of the position estimation error grows at most linearly with time (or distance traversed) asymptotically. The bias growth rate is crucially dependent on the trajectory of th...

Error growth in position estimation from noisy relative pose measurements

We examine how the estimation error grows with time when a mobile robot estimates its location from relative pose measurements without global position or orientation sensors. We show that in both 2-D or 3-D space, both the bias and variance of the position estimation error grows at most linearly with time (or distance traversed) asymptotically. The bias is crucially dependent on the trajectory ...

Cost-Benefit Analysis and Relative Position

there is no reason to think that the losers, in terms of relative position, had any entitlement to their antecedent relative position; and we are not, after all, speaking of redistribution from poor to rich. On distributional concerns and cost-benefit analysis, see various papers in Symposium, J. Legal Stud.

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...
