A simple technique for measuring with high accuracy relative wire positions in MWPCs

Nuclear Instruments and Methods in Physics Research, 1981
Abstract A simple technique is described which makes it possible to check with high accuracy the relative positions of wires in MWPCs. The method makes use of Moire fringes to spot wires which deviate from the regular wire spacing. A 20 μm deviation can easily be seen in chambers with a wire pitch of a few mm.

A Method for Evaluation of the Error Function of Real and Complex Variable with High Relative Accuracy

Publications of the Research Institute for Mathematical Sciences, 1983
A method for evaluation of the error function of real and complex variable by means of a trapezoidal sum with a correction term is proposed. This method gives a result with high relative accuracy with small number of operations. A precise upper bound of the relative error of the approximation for real variable is given.

A novel ambiguity search algorithm for high accuracy differential GNSS relative positioning

Aerospace Science and Technology, 2018
Abstract It is well understood that the key to high accuracy differential global navigation satellite system (DGNSS) relative positioning is the resolution of the integer ambiguities within the carrier phase measurements and the continuous tracking of them. The resolution process is usually converted into an integer least square optimization problem,
