Position Accuracy of Drilled Holes
CIRP Annals, 1991When selecting hole-making sequences, the positional accuracy mainly is determined during the first drilling operation. This dissertation consists of three papers which consider the influence of various factors on hole positional accuracy when drilling in inclined workpieces using high-speed steel twist drills with conventional point geometry.

Positioning Accuracy Improvement With Differential Correlation
IEEE Journal of Selected Topics in Signal Processing, 2009The success of satellite navigation in the mass consumer market will depend greatly on its performance in deep urban and moderate indoor environments. The signal obstructions in these environments lead to low signal-to-noise ratios, which substantially degrade the positioning accuracy of GPS and Galileo receivers. New ranging techniques are required to

Accuracy in positioning of handheld instruments
Proceedings of 18th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2002Microsurgery with handheld instruments requires accurate positioning. The attainable degree of accuracy depends on the amplitude of the components of error, from whatever source, in hand motion. Here, the authors quantify attainable accuracy in positioning of handheld instruments over a 1 min time span. No prefiltering of measured data is used.

Accuracy of position and track
2004Catastrophic marine accidents are rare. Of those collisions and standings which do occur, many start as quite routine navigational situations; just another night, just another watch, just another target. Something then goes awry perhaps the radar fails to display an islet or a target's calculated closest point of approach (CPA) is erroneous ...

Position Accuracy of Celestial Fixes
Journal of Navigation, 1994For centuries, celestial navigation was the main method of determining a ship's position at sea, especially when sailing into more exotic areas. Later on, vast areas of the oceans were only covered by the Omega system and there was still every opportunity of finding a position by using the sextant.
