The invention discloses a ship shielding prediction method in satellite communication, which belongs to the technical field of maritime satellite communication, and comprises the following steps: dividing a voyage into a plurality of road sections, and setting the longitude and latitude of a satellite and the longitude and latitude of a starting point and an ending point of each road section; obtaining a shielding course angle range of the ship in the road section according to the longitude and latitude of the starting point and the ending point of each road section; obtaining the course angle of the ship in the road section and the mast shadow length according to the longitude and latitude of the starting and ending points of each road section; the course angle corresponding to each road section is compared with the shielding course angle range, and the road section with the course angle within the shielding course angle range and the mast shadow length larger than zero is listed as a shielding path, so that a captain and communication personnel can be helped to prepare for satellite communication shielding in advance, and the execution of a navigation task is prevented from being influenced; the method is of great significance to ship navigation tasks.
本发明公开了一种卫星通信中船只遮挡预测方法,属于海上卫星通信技术领域,其包括将航程划分为多个路段,并设置卫星经纬度以及每个路段的起止点经纬度;根据每个路段的起止点经纬度得到船舶在该路段的遮挡航向角范围;根据每个路段的起止点经纬度得到船舶在该路段的航向角以及桅杆阴影长度;对比每个路段对应的航向角与遮挡航向角范围,将航向角处于遮挡航向角范围内并且桅杆阴影长度大于零的路段列为遮挡路径,从而可以帮助船长和通信人员提前为卫星通信遮挡做准备,避免航行任务执行受到影响,对于船舶航行任务具有重要的意义。
