Preizkus instrumenta Leica Nova MS50 po standardiziranemu postopku ISO 17123-5 : diplomska naloga = Testing of the Leica Nova MS50 instrument according to the standard procedure ISO 17123-5 : graduation thesisVračar, IrisRazvoj merskega instrumentarija v geodeziji je privedel do tega, da je terenski zajem meritev hiter. Večinoma gre za elektronske naprave, ki poleg merskih senzorjev vključujejo tudi procesorske in ... pomnilniške enote. Torej pri geodetskih instrumentih razpolagamo dejansko z mini računalniki, ki omogočajo preračun merskih vrednosti v končne rezultate že na terenu. Pri elektronskih tahimetrih v postopku polarne izmere merimo polarne količine do posameznih točk: horizontalne smeri, zenitne razdalje in poševne dolžine. S preračunom v instrumentu dobimo in hkrati izvozimo ''merjene'' koordinate točk. Kakšna je natančnost merjenih koordinat z izbranim tahimetrom, preverimo s standardiziranim postopkom, ki je predpisan s strani Mednarodne organizacije za standardizacijo % ISO. Ravno za potrebe določitve natančnosti tahimetrov pri določanju koordinat točk je bil razvit standardiziran postopek oziroma standard ISO 17123-5. Dokument, v katerem je zapisan standard ISO 17123-5:2018, predpisuje postopek terenskih meritev in izračuna, ki ga uporabljamo za določitev in ocenjevanje natančnosti merjenja koordinat z elektronskim tahimetrom ter z dodatno opremo, ki je pri meritvah potrebna. Postopek je nastavljen tako, da omogoča testiranja kateregakoli elektronskega tahimetra ter da minimizira vpliv atmosfere. V diplomski nalogi smo izvedli dva terenska preizkusa: poenostavljeni ter popolni preizkus. Vsak preizkus smo izvedli na dva načina: z oziroma brez (ročne) uporabe avtomatskega viziranja tarč. Poskušali smo v večji meri upoštevati vse predpise standardiziranega postopka ter na koncu določili oceno natančnosti merjenih koordinat. Empirično določeni standardni odklon smo v postopku statističnega testiranja primerjali z natančnostjo, ki jo podaja proizvajalec instrumenta. Upoštevali smo tudi vse dodatne vplive, ki slabšajo natančnost, da bi na koncu določili realno natančnost koordinat polarno merjenih točk.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - [Ljubljana : I.
