When any one tracing positional Pi except the tracking initiation position P1, by the communication antenna 2 before the ship is located at
Most strong tracking sense Di-1 when one tracing positional Pi-1 is known as 0:00 direction, first passes through the gyroscope 8, measures institute
Communication antenna 2 is stated in the deviation angle α and offset direction of the signal transmitting and receiving direction d relative to the 0:00 direction at current time,
The signal transmitting and receiving direction d for controlling the communication antenna 2 in the following manner again is rotated in horizontal plane to signal peak direction:
It sets the step pitch angle of the second stepper motor 3-2 to its one or more minimum step angles, controls
The second stepper motor 3-2 drives the signal transmitting and receiving direction d of the communication antenna 2 more towards being reversed for the offset direction
Secondary rotation (such as: in Fig. 2, signal transmitting and receiving direction d tracing positional Pi at is relative to 0:00 direction i.e. most strong tracking sense
The offset direction of Di-1 is that counterclockwise, then the signal transmitting and receiving direction d for controlling the communication antenna 2 is rotated clockwise),
And the angle rotated each time is step pitch angle set by the second stepper motor 3-2, also, same what is rotated each time
When, by the communication antenna 2, the mobile communication signal that receives is compared after rotating each time, until compare obtain it is described
Certain rotating character of communication antenna 2 closes signal peak condition, then by the signal transmitting and receiving direction d of the communication antenna 2 in this time
The direction of rotation is denoted as the signal peak direction, and the signal transmitting and receiving direction d for controlling the communication antenna 2 is rotated in horizontal plane
To the signal peak direction, the signal peak direction, that is, communication antenna 2 is located at current tracing positional in the ship
Most strong tracking sense Di when Pi；Wherein, the signal peak condition are as follows: rotated respectively to preceding n times from certain primary rotation
It is rotated with rear n times, the signal strength of mobile communication signal received by the communication antenna 2 is in the trend weakened one by one, N
Value for positive integer, N is bigger, then the most strong tracking sense Di traced into more accurate but required calculation amount is also got over
Greatly.
In addition, the size of step pitch angle set by the second stepper motor 3-2, depends on the deviation angle α, it is described
Deviation angle α is bigger, then set step pitch angle is bigger, to avoid " too small step pitch angle causes the communication antenna 2
Rotation speed it is excessively slow, cause the signal transmitting and receiving direction d of the communication antenna 2 to fail to be located at current trace bit in the ship
The problem of being rotated when setting Pi to the most strong tracking sense Di "；But set step pitch angle can not be excessive, with
Avoid the accuracy of the most strong tracking sense Di traced into too low.
