我们开发了一种多频率、多全球导航卫星系统(GNSS)定位仪器,针对冰冻圈的自主应用进行了优化。与市售方案相比,该仪器的功耗要求更低,成本和重量也更小,简化了现场使用和相关物流。在本文中,我们评估了极地环境中相对于通常用于冰川学应用的大地测量接收器性能的几个基线方面。对定位精度和相对精度的评估显示,该仪器具有毫米至厘米级(“大地测量级”)的质量,使其成为GNSS冰川学和地球物理应用(如监测地表高程变化和冰流)的竞争性替代方案。在格陵兰冰原的现场测试中,这些仪器的阵列也证明了整个极地冬季的稳健性,并满足了功率和可靠性要求。
We developed a multi-frequency, multi-Global Navigation Satellite System (GNSS) positioning instrument optimized for autonomous applications in the cryosphere. At lower power requirements and a fraction of the cost and weight compared to commercially available options, this instrument simplifies field usage and associated logistics. In this paper, we assess several baseline aspects of performance in a polar environment relative to geodetic receivers commonly used for glaciological applications. Evaluations of precision and relative accuracy of positioning show millimeter to centimeter-level (‘geodetic-grade’) quality of this instrument, making it a competitive alternative for GNSS glaciological and geophysical applications such as monitoring surface elevation change and ice flow. An array of these instruments, tested in the field on the Greenland Ice Sheet, also demonstrated robustness throughout the polar winter and met power and reliability requirements.
