The idiographic behave is that after certain distance propagation, the signal strength of sky wave will exceed the strength of ground wave apparently, it makes the receiver lock on the sky wave by error and the positioning result will deviate from the actual position.

其具体表现为：在传播一定距离后，天波信号强度远大于地波，导致接收机错误的锁定在天波上，使系统解算结果偏离实际载体位置。
