29. LGC open-source: a strategy to share adjustment software and algorithmic development (T24)

Guillaume Kautzmann (CERN)

LGC (Logiciel Général de Compensation) is a software that computes position estimates and associated statistics based on observations obtained by CERN surveyors. Since the mid-1980s, LGC has been a crucial tool to perform geodetic computations in various contexts - from simple levelling campaigns to advanced monitoring projects. The CERN Geodetic Metrology group continues to maintain, improve,...

30. CoToLiP, a new tool to handle each of the six degrees of mutual situation between any two integral features. (T25)

ToLiP, or minimum set of situation features made of (at most) a poinT On a Line In a Plane, has been introduced as an intermediate object between any integral feature's geometry and the coordinate system representing its situation (location and orientation). CoToLiP is the tool to deal with the composition of two ToLiPs. The paper gives background on how this is built and used to encode...

58. Calibration of a New Generation of High Speed and High Precision Measuring Instrument - Vision Measuring Instrument (A3)

CEPC, the next generation of particle colliders which is in planning. The storage ring of CEPC is 100 km long, and the collimation accuracy between adjacent precollimation units is better than 0.1mm. The measurement speed of traditional laser tracker measurement method can not meet the requirements of construction period. This report presents a new measuring instrument based on photogrammetric...

59. Multilateration Method for Pre-Alignment of High Energy Photon Source Storage Ring (A4)

In order to achieve 10μm pre-alignment accuracy of high energy photon source (HEPS) storage ring in transverse and vertical, four laser trackers were used for set up a four-station multilateration measurement system. Experiment results show that the absolute position measurement accuracy is within 7.1μm. Three pre-alignment standard workstations have been established. And the laser...
