渔获运输船动态监控数据

渔船与渔获运输船需要进行渔获转载工作，渔船关注相关运输船后，系统为渔船提供关注的渔获运输船最新状态信息及相关提醒，比如开始航行提醒、停泊提醒，距离提醒、预计航程等1、根据渔船和运输船的位置、地球极半径和赤道半径运用椭圆体上计算两点距离算法精确计算椭圆体地球上两个船的距离，根据经纬度位置、航速和航向计算得出相对航速、相对航向、真方位角，再计算出最近会遇距离和最近会遇时间，并根据最新船位实时刷新数据。
2、运输船航速大于3节时，提示渔船运输船口已开航，持续减到3节以下后提示渔船运输船已停航。
3、运输船距离渔船5海里后，提示渔船运输船即将到达。

For fishing vessels and fishery transport vessels engaged in fishery catch transfer operations, after a fishing vessel follows a relevant transport vessel, the system provides the fishing vessel with the latest status information and related reminders of the followed transport vessel, including sailing start reminders, berthing reminders, distance reminders, estimated voyage, etc.
1. Accurately calculate the distance between the two vessels on the ellipsoidal Earth using the two-point distance calculation algorithm on the ellipsoid, based on the positions of the fishing vessel and the transport vessel, as well as the Earth's polar radius and equatorial radius. Calculate the relative speed, relative course, and true bearing based on their longitude and latitude coordinates, speed over ground, and course over ground, then derive the closest point of approach (CPA) distance and time to closest point of approach (TCPA), and refresh the data in real time based on the latest vessel positions.
2. When the speed of the transport vessel exceeds 3 knots, send a reminder to the fishing vessel that the transport vessel has departed. After its speed continuously decreases to below 3 knots, send a reminder to the fishing vessel that the transport vessel has stopped sailing.
3. When the distance between the transport vessel and the fishing vessel reaches 5 nautical miles, send a reminder to the fishing vessel that the transport vessel is about to arrive.
