    • PURPOSE: A tactical data link system based on a point to multi-point network and a tactical data transmission method thereof are provided to form an improved communications system in comparison with a method using a physical layer address, thereby preventing the decrease of transfer efficiency due to a 15-bit overhead. CONSTITUTION: Tactical data link(Link-16) units(501,502,503) each have an allocated track number(TN). The tactical data link unit transmits a data packet using an IP server/client method. A gateway(504) supports connection between networks using a point-to-multipoint method through each tactical data link unit having the allocated track number and a Link-16 network. A router is connected to the gateway. The router routes the data packet from a source IP address to a destination IP address. An IP server(505) receives the data packet using a point-to-point method.

    • The present invention relates to a method for coping with GPS radio disturbance. The method comprises the steps of: receiving a GPS signal in a transmitting system from a satellite through a GPS receiver, determining whether the status of the received GPS signal is normal, and determining whether an initial GPS deception has occurred if the status of the received GPS signal is normal; using the position data of target data including the same track data as the track data of the transmitting system as the position data of the transmitting system if the initial GPS deception has occurred, setting the predetermined value of position quality included in ship data as zero, and setting the value of a GPS spoofing indicator which indicates that the initial GPS deception has occurred as one; and determining whether the value of the GPS spoofing indicator is set as one if the initial GPS deception has not occurred, and setting the value of the position quality included in the ship data as a value greater than zero if the value of the GPS spoofing indicator is not set as one. [Reference numerals] (AA) Receive a GPS signal (every second); (BB) Transmit ship data (every six seconds); (CC) Receive target data (every three seconds); (DD) GPS deception track; (EE) Normal track; (FF) Ship position = GPS data position; (GG) The initial GPS deception occurs (over 琯); (HH) Set Gpq = 0; (II) Transmit ship data where Gpq = 0; (JJ) Continue GPS deception (over 貫); (KK) Ship position = Target data position; (LL) Release GPS deception (below 貫); (MM) Set Gpq > 0; (NN) Ship position = GPS data position; (OO) Transmit ship data where Gpq > 0
    • 本发明涉及一种应对GPS无线电干扰的方法。 该方法包括以下步骤:通过GPS接收机从卫星在发射系统中接收GPS信号,确定所接收的GPS信号的状态是否正常,以及如果所接收的GPS信号的状态是否已经发生初始的GPS欺骗, GPS信号正常; 如果发生初始GPS欺骗,则使用包括与发送系统的轨道数据相同的轨道数据的目标数据的位置数据作为发送系统的位置数据,将船舶数据中包括的位置质量的预定值设置为零, 并设置GPS欺骗指示器的值,表示初始GPS欺骗已经发生为一个; 并且如果没有发生初始GPS欺骗,则确定GPS欺骗指示符的值是否被设置为一,并且如果GPS欺骗指示符的值,则将包括在船舶数据中的位置质量的值设置为大于零的值 没有设置为一个。 (附图标记)(AA)接收GPS信号(每秒); (BB)发送船数据(每6秒); (CC)接收目标数据(每三秒钟); (DD)GPS欺骗轨道; (EE)正常轨道; (FF)船位= GPS数据位置; (GG)最初的GPS欺骗发生(超过琯); (HH)Set Gpq = 0; (II)发送Gpq = 0的船舶数据; (JJ)继续GPS欺骗(过贯); (KK)船位=目标数据位置; (LL)发布GPS欺骗(下文); (MM)设置Gpq> 0; (NN)船位= GPS数据位置; (OO)发送船舶数据,其中Gpq> 0
