Ocena vpliva megle na kakovost relativne določitve položaja z GNSS : diplomska naloga = Assessment of the effect of fog on GNSS relative positioning quality : graduation thesis
Šinkovec, Anja, 1996-
Na kakovost določitve položaja točke z GNSS vpliva več dejavnikov. Eden od njih je troposferska refrakcija, ki predstavlja zakasnitev signala GNSS v troposferi. Za odstranitev vpliva so do sedaj ...razvili številne modele troposferske refrakcije, v katerih je glavni problem modeliranje vsebnosti vodne pare v ozračju, saj se ta nenehno časovno in prostorsko spreminja. V najnižji plasti troposfere se vodna para lahko kondenzira v meglo. Cilj diplomske naloge je ugotoviti, ali ta meteorološki pojav znatno vpliva na kakovost relativne določitve položaja z GNSS. S tem namenom smo v programu Leica Infinity obdelali 10-dnevna opazovanja GNSS s treh stalno delujočih postaj, ki se nahajajo v Ljubljanski kotlini, kjer se megla pogosto pojavlja. Končni rezultat so bile koordinate dveh novih točk, ki smo jih določili z metodo radialne izmere. Vpliv megle smo ocenili na osnovi primerjave izračunanih koordinatnih razlik za posamezno točko. Rezultati kažejo, da prisotnost megle bistveno ne vpliva na kakovost relativno določenega položaja z GNSS.
