Cumberland Precise Point Positioning - Float Deployed 2019-07-24

The Precise Point Positioning Float AR 37 was deployed on 2019-07-24 at Cumberland. Cumberland is located in the Comox Valley on Vancouver Island in British Columbia. This device is a Precise Point Positioning - Float. These precise point positioning processors are modules as part of an aggregate systems for the Earthquake Early Warning (EEW) installations. Within these processors, specially designed filters are applied to Global Navigation Satellite System and accelerometer input data. The processors output supports epicentre location and magnitude estimates for the larger earthquake detection system. This category corresponds to the floating point ambiguity resolution (AR) stream. It was deployed on a fixed platform. Data from this deployment were archived and made available through Ocean Networks Canada's Oceans 2.0 digital infrastructure, with quality assurance and derived data products following established practices.

精密单点定位浮点模糊度解算37号设备（Precise Point Positioning Float AR 37）于2019年7月24日部署于坎伯兰（Cumberland）。坎伯兰坐落于不列颠哥伦比亚省温哥华岛上的科莫克斯谷（Comox Valley）。该设备为精密单点定位-浮点型设备（Precise Point Positioning - Float）。此类精密单点定位处理器作为地震预警（Earthquake Early Warning, EEW）集成系统的组成模块，服务于地震预警设施部署。在该类处理器中，针对全球导航卫星系统（Global Navigation Satellite System）与加速度计（accelerometer）输入数据应用了定制设计的滤波算法。处理器的输出结果可支持大型地震监测系统开展震中（epicentre）定位与震级估算工作。该数据集类别对应浮点模糊度解算（Floating Point Ambiguity Resolution, AR）数据流。该设备部署于固定平台。本次部署产生的数据已完成归档，并通过加拿大海洋网络（Ocean Networks Canada）的Oceans 2.0数字基础设施对外开放；数据的质量保证与衍生产品生产均遵循既定行业规范。
