摘要

在大地测量学中，高度(海拔)的确定面临着直接归因于测量方法和使用的大地水准面解的问题。由于CROPOS的可靠性以及大地水准面确定技术的不断进步(其外部和内部精度的提高)，使用CROPOS_VRS_HTRS96 VPPS服务的GNSS观测成为克罗地亚日常大地测量实践中最常用的高度确定方法。本文描述了利用CROPOS_VRS_HTRS96 VPPS服务和几何水准在萨格勒布市地区建立33个GNSS/水准点。本文还分析了GNSS观测的质量，分析和比较了克罗地亚共和国、HRG2000和HRG2009官方大地水准面解决方案的大地水准面波动与GNSS/水准测量获得的已建立的GNSS/水准测量点的波动，并简要概述了萨格勒布市垂直网络的现状。

Accuracy validation of official Croatian geoid solutions over the area of City of Zagreb

Height (altitude) determination in geodesy is faced with problems that are directly attributed to the method of measurements and used geoid solutions. Due to the reliability of CROPOS as well as growing progress in geoid determination (increase of their external and internal accuracy), GNSS observations using CROPOS_VRS_HTRS96 VPPS service became most commonly used method of height determination in Croatian every day geodetic practice. This paper describes establishment of 33 GNSS/levelling points using CROPOS_VRS_HTRS96 VPPS service and geometric levelling at the area of the City of Zagreb. It also gives the analysis of the quality of performed GNSS observations, analysis and comparison of the geoid undulations from official geoid solutions of the Republic of Croatia, HRG2000 and HRG2009 with undulations obtained by GNSS/levelling for established GNSS/levelling points and brief overview of current state of vertical network of the City of Zagreb.
