通过墨卡托投影,将船舶所处位置地理坐标转换平面坐标,再由平面坐标转换为屏幕坐标,同时将海图按Inmarsat系统作用区域进行划分,推导出每块区域边缘曲线公式,从而可以判断出该船所在的洋区以及与卫星之间的距离,以选择对应卫星进行通信。
In hydrographic sweeping survey,considering that the surveyed route in design project description is a longer route which is composed of two geodetic coordinates,methods of Mercator projection,UTM(Universal Transverse Mercator) projection and Gauss-Kruger projection were adopted to eliminate the direction deviation of sweeping survey,and conform to the conventional way of sweeping survey as well.
