    • A method comprising determining coordinates of a first point rigidly attached to a rigid body floating on the sea surface in a desired coordinate reference frame; measuring orientation parameters of the rigid floating body to determine 3D offset in the coordinate reference frame of the first point to any point on or rigidly attached to the body; applying a 3D coordinate shift from the first point to a second point rigidly attached to the body, thus determining coordinates of the second point in the desired reference frame; determining a distance from the second point to one or more devices that are components of a seismic acquisition spread, by comparing transmission times of a signal to recording times of transmitted signals and multiplying by a signal propagation rate; and determining relative positions of components of the spread to each other and to devices rigidly attached to the rigid body.
    • 一种方法,包括确定在期望的坐标参考系中刚性附着到漂浮在海面上的刚体的第一点的坐标; 测量所述刚性浮体的定向参数以确定所述第一点的坐标参考系中的三维偏移到刚体或刚性地附接到所述体的任何点; 应用从第一点到刚性附接到身体的第二点的3D坐标移位,由此确定期望参考帧中的第二点的坐标; 通过将信号的传输时间与传输信号的记录时间进行比较并乘以信号传播速率来确定从第二点到作为地震采集扩展的组成部分的一个或多个设备的距离; 以及确定涂层的组分相互之间的相对位置以及刚性地附接到刚性体的装置的相对位置。

    • Methods and systems for estimating one or more orientation parameters of a seismic apparatus are described. One method comprises initiating an acoustic signal from an acoustic transmitter in a marine seismic spread comprising a streamer, the streamer having at least two nodes separated by a fixed distance; measuring a first and a second difference in acoustic arrival times at the nodes for the acoustic signal; and using change in the second difference from the first difference to estimate orientation of the streamer. It is emphasized that this abstract is provided to comply with the rules requiring an abstract, which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).
    • 描述用于估计地震装置的一个或多个取向参数的方法和系统。 一种方法包括在包括流光船的海洋地震展开中发起来自声发射器的声信号,所述拖缆具有至少两个分开一定距离的节点; 测量声信号的节点处的声到达时间的第一和第二差; 并且使用与第一差异的第二差异的改变来估计流光的方向。 要强调的是,该摘要被提供以符合要求摘要的规则,这将允许搜索者或其他读者快速确定技术公开的主题。 提交它的理解是,它不会用于解释或限制权利要求的范围或含义。 37 CFR 1.72(b)。
