The ongoing contribution of the Greenland Ice Sheet (GIS) to sea level rise is of continuing interest to the scientific community, policymakers, and the population at large. Geodetic determination of ice sheet mass loss is at the center of research on GIS contributions to sea level rise. There are many means for determining mass loss, but almost all rely on some form of satellite positioning, generally using the Global Navigation Satellite System (GNSS) or its subset Global Positioning System (GPS). The goals of the workshop are to 1) determine the community need for the current GNSS observation network in Greenland, 2) outline the science requirements for the network design, 3) define the path forward for the existing GNSS network, and 4) identify improvements to the existing network that will benefit the broader science community. Per broader impacts, the workshop will bring together investigators using data produced by the current network along with potential new investigators who can make use of GNSS network data. The workshop conveners plan to recruit participants from a spectrum from junior to senior scientists, and increase the diversity of the workshop participants wherever possible, by including funded invitations.The objective of this workshop is to convene a 1.5 day workshop at NASA Goddard Space Flight Center in January 2017, with the purpose of defining a path forward for a Global Navigation Satellite System (GNSS) observation network in Greenland. The workshop will be held in conjunction with the 2017 NASA PARCA (Program for Arctic Regional Climate Assessment) Meeting. The goals of the workshop are to elucidate the current state of the GNSS network, illustrate the current uses of the network data (e.g., geodesy, crustal deformation, atmospheric modeling, space weather) and identify potentially new uses of the data, and determine the optimal configuration of the network moving forward (e.g., the ideal number of stations, the placement of stations, the replacement and upgrade of stations, and data management).

格陵兰冰盖（GIS）对海平面上升的持续贡献是科学界，政策制定者和整个人口的持续兴趣。冰盖质量损失的大地测定是GIS对海平面上升的贡献的研究中心。确定质量损失的方法有很多，但是几乎所有人都依赖某种形式的卫星定位，通常使用全球导航卫星系统（GNSS）或其子集全球定位系统（GPS）。 研讨会的目标是1）确定社区对格陵兰岛当前GNSS观察网络的需求，2）概述网络设计的科学要求，3）定义现有GNSS网络的前进道路，4）确定改进到现有的网络，将使更广泛的科学界受益。通过更广泛的影响，研讨会将使用当前网络生成的数据以及可以利用GNSS网络数据的潜在新调查人员将调查人员聚集在一起。研讨会召集人计划通过包括资助的邀请函来招募从初级科学家到高级科学家的参与者，并尽可能地增加研讨会参与者的多样性。该研讨会的目标是在NASA Goddard太空飞行中心举行1.5天的工作坊。 2017年1月，为格陵兰岛的全球导航卫星系统（GNSS）观察网络定义了前进的道路。 该研讨会将与2017年NASA PARCA（北极地区气候评估计划）会议共同举行。研讨会的目标是阐明GNSS网络的当前状态，说明了网络数据的当前用途（例如，地球，地壳变形，大气建模，空间天气）并确定数据的潜在使用，并确定数据的新用途，并确定网络向前移动的最佳配置（例如，位置的理想数量，位置的位置，替换和升级电台以及数据管理）。
