Opis:: Ice factories, meat processing plants and breweries around the world rely on the refrigeration technology experts from GEA Refrigeration Germany GmbH. Based in Berlin, the company manufactures highly precise screw compressors, the heart of the cooling systems. In order to ensure and improve the quality and energy efficiency of its compressors, the company strives to permanently eliminate errors in design and production, and at its suppliers. Three ZEISS coordinate measuring machines, as well as ZEISS CALYPSO and ZEISS GEAR PRO software are helping the company come closer to its goals.

Opis:: An uninterrupted information about the user’s position can be obtained generally from satellite navigation system (SNS). At the time of this writing (January 2017) currently two global SNSs, GPS and GLONASS, are fully operational, two next, also global, Galileo and BeiDou are under construction. In each SNS the accuracy of the user’s position is affected by the three main factors: accuracy of each satellite position, accuracy of pseudorange measurement and satellite geometry. The user’s position error is a function of both the pseudorange error called UERE (User Equivalent Range Error) and user/satellite geometry expressed by right Dilution Of Precision (DOP) coefficient. This error is decomposed into two types of errors: the signal in space ranging error called URE (User Range Error) and the user equipment error UEE. The detailed analyses of URE, UEE, UERE and DOP coefficients, and the changes of DOP coefficients in different days are presented in this paper.
