CERN complex alignment - geodesic measurements • Theodolites, tachometers, trackers and reflectors • Angles • Distances dR3 • Levels and staffs ϕ • Offsets to horizontal planes d • Ecartometers dR2 H2 • Offsets to vertical planes H1 β • Tilt sensors dH • Inclinations dR1 ß 3
In-field acquisitions - Divergences & similarities Measurement: Repetitive Diversify Tolerances: Well-defined Variable Sequence: Controlled Non-existent Main user: Industrial Support CERN STAFF Coord. System: Global Local Most processing: Postpone Immediate Business model: Elements, points, networks, geodetic measurements,… Instrument: Communication librairies Calculation: Survey Software dependencies 4
Main drawbacks • From 90’s, in VB6 and VBA ≈ 600 lines • GUI are French only • Not “touch screen” friendly • Maintenance 14 levels of • New instruments + computing libraries replacement conditional >>> double implementation statements • Performed by several surveyors >>> duplicate parts + Procedural and OO programming T he The challenge S urvey U nified • Unify survey data acquisition tools; N otebook for • Facilitate the maintenance; A lignment and M easurement • Open doors to more up to date interfaces. I nterventions Rewriting of a single application that fulfil all the constraints 5

Status of the development First iterations • Design Artefacts • Prototype • Managers & dependencies; • Ecartometry, levelling & Theodolite. Next iterations • Architectural choices + implementation: • Tilt measurement; • Guided modules. 16
Summary & Outlook 2 data acquisition software >> TSUNAMI (2 user modes) • Development in progress… • Global architecture delivered >> Satisfy constraints + ensure quality • Most core functionalities implemented • Full-scale tests (next year) • CERN survey team >> feedback >> Corrections and adjustments • First version >> next long shutdown • Architecture + documentation >> ease the maintenance • Achieved modularity >> stimulate extensions >> reuse of code in future projects. 17
Thank you for your attention. Thank you. 18
