nav (a1)

On sea-based mobile ARM deployments, several instruments depend on the ship’s current position and "attitude". The NAV system reads the ship’s current position (latitude and longitude) as well as its "attitude" (roll, pitch, and yaw angles). This data is collected for both near-real-time and post-deployment processing of instrument data.在海基移动ARM部署作业中，多台仪器的运行依赖船舶的当前位置与“姿态”信息。导航系统（NAV）可读取船舶的当前位置（经纬度）以及其姿态参数，包括横摇角、纵摇角与首摇角。此类数据会被采集，用于仪器数据的近实时处理与部署后处理。
