Port Alberni Precise Point Positioning - Float Deployed 2022-03-24

The Precise Point Positioning Float AR 20 was deployed on 2022-03-24 at Port Alberni. Port Alberni is a city located on Vancouver Island. 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 3.0 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20型设备（Precise Point Positioning Float AR 20）于2022年3月24日部署在阿尔伯尼港（Port Alberni），该港市坐落于温哥华岛。本设备属于精密单点定位-浮点型（Precise Point Positioning - Float）设备。此类精密单点定位处理器为地震预警（EEW）集成系统的组成模块。在该类处理器中，会对全球导航卫星系统（Global Navigation Satellite System）与加速度计的输入数据施加定制化滤波处理。该处理器的输出可为大型地震探测系统提供震中位置与震级估算结果。本数据集对应浮点模糊度解算（AR）数据流。该设备部署于固定平台。本次采集的数据已完成归档，并通过加拿大海洋网络（Ocean Networks Canada）的Oceans 3.0数字基础设施对外共享，其质量保障流程与衍生数据产品均遵循行业既定规范。
