Description (Dublin Core)

hrv U radu su opisana fizikalna svojstva i poboljšanja GPS-antene Zephyr Geodetic. Ta antena omogućava vrlo precizna mjerenja, s vrlo malim smetnjama, jer umanjuje utjecaj multipath efekta. Osim toga, ima više pobudnih mjesta tako da su u njoj manja zaostajanja signala. Iz usporedbe te antene s poznatom Choke ring antenom, vidi se, da se sa Zephyr Geodetic antenom postižu rezultati usporedivi s Choke ring antenom, a djelomično i bolji na malim elevacijskim kutovima satelita (Krantz i dr. 2001b). Stoga ne čudi da su mjerenjima koja su izvedena sa Zephyr Geodetic antenom na kalibracijskoj bazi Geodetskog fakulteta Sveučilišta u Zagrebu postignuti izvrsni rezultati (Solarić i dr. 2008).
eng The paper describes physical properties and improvements of the GPS-antenna Zephyr Geodetic. It enables very precise measurements, with very small disturbances because it reduced the influence of multiple effects. Apart from that, the antenna has got more enhancing items so that there are lees signal delays present. From the comparison the antenna with well known Choke ring antenna it can be seen that there are results obtained with Zephyr Geodetic antenna comparable with the results obtained with Choke ring antenna, and they are partly even better at smaller elevation angles of the satellite (Krantz et al. 2001b). It is therefore no wonder that the results obtained with the measurements performed with Zephyr Geodetic antenna at the calibration base of the Faculty of Geodesy, University of Zagreb, are excellent (Solarić et al. 2008).
