Abstract

Abstract The Nordic Geodetic Commission (NKG) has launched a joint NKG GNSS Analysis Centre that aims to routinely produce high qualityGNSS solutions for the common needs of the NKG and the Nordic and Baltic countries. A consistent and densified velocity field is needed for the constraining of the gla-cial isostatic adjustment (GIA) modelling that is a key component of maintaining the national reference frame realisations in the area. We described the methods of the NKG GNSS Analysis Centre including the defined processing setup for the local analysis centres (LAC) and for the combination centres.We analysed the results of the first 2.5 years (2014.5-2016). The results showed that different subnets were consistent with the combined solution within 1-2 mm level. We observed the so called network effect affecting our reference frame alignment. However, the accuracy of the reference frame alignment was on a few millimetre level in the area of the main interest (Nordic and Baltic Countries). TheNKGGNSS AC was declared fully operational in April 2017.

北欧和波罗的海全球导航卫星系统分析中心的初步结果

北欧大地测量委员会(NKG)启动了一个联合GNSS分析中心，旨在为NKG以及北欧和波罗的海国家的共同需求提供高质量的GNSS解决方案。一个一致和致密的速度场需要约束冰川均衡调整(GIA)模型，这是维持该地区国家参考框架实现的关键组成部分。我们描述了NKG GNSS分析中心的方法，包括为本地分析中心(LAC)和组合中心定义的处理设置。我们分析了前2.5年(2014.5-2016)的结果。结果表明，不同子网在1 ~ 2mm范围内与组合溶液一致。我们观察到所谓的网络效应影响我们的参考框架对齐。但是，在主要感兴趣的地区(北欧和波罗的海国家)，参考系对准的精度只有几毫米。kggnss AC于2017年4月宣布全面运行。
