On the line of one mark rod 3 and second mark rod 4, the direction-finding device is used to measure first mark rod 3 and described
The azimuth of the line of second mark rod 4.
Normally, the rotating disk 1 is rotatably installed on tripod or other kinds of support.The antenna substrate 2,
Position relationship between first mark rod 3, the second mark rod 4 and direction-finding device is relatively fixed.
The antenna substrate 2 is generally rectangle or ellipse, and mark rod and direction-finding device are typically placed along long axis direction.
, it is necessary to be aligned to the first mark rod 3, the original utilized in addition during direction finding during progress initial orientation before direction finding
Reason be the line of two mark rods with when the center line of direction finding optical device 7 is aligned, to measure the line of two mark rods
Azimuth., it is preferable that the center of the line of first mark rod 3 and second mark rod 4 and the antenna substrate 2
Axis is overlapped.
In order to ensure typically to be spaced one between the accuracy of initial orientation and the accuracy of direction finding result, two mark rods
Fixed distance.Orientation equipment is also related to the distance for treating direction finding optical device 7 when this is apart from general and direction finding, if both
It is distant, then also should be apart from each other between two mark rods, if both is closer to the distance, between two mark rods
Can be at a distance of more closer.Also there is certain requirement additionally, due to the size of antenna substrate 2, it is too small can not to ensure the essence of alignment
Degree, too conference cost inconvenient for use is too high.The length of general antenna substrate 2 is at 1-3 meters or so.
Specifically, when carrying out direction finding based on said structure, it is possible to use double GPS direction findings, can also using electronic compass or
Person's fibre optic gyroscope carries out direction finding.

Rotation.So, when alignment, electric rotating machine driving rotating disk 1 rotates, so that drive antenna substrate 2 and mark rod to rotate,
When the line of the first mark rod 3 and the second mark rod 4 is with when the center line of direction finding optical device 7 is aligned, treating that direction finding optics is set
The laser of standby 7 luminescence unit outgoing reaches the first light-receiving list of the second mark rod 4 by the light hole of the first mark rod 3
Member, now the first light receiving unit of the second mark rod 4 detects optical signal, so as to control the electric rotating machine to stop the rotation.
Keep present orientation constant, azimuth is measured using direction-finding device.
But the initial alignment of above-mentioned external optical orientation equipment is (i.e. by the first mark rod 3 with treating direction finding optical device 7
Center line alignment) still need manual-alignment, and in order to realize automatic initial alignment, can the first mark rod 3 light hole
Second light receiving unit is also installed at position, and automatic travelling device is installed (such as by motor-driven in frame bottom
Pulley), second light receiving unit is communicated to connect with the automatic travelling device.The automatic travelling device drives support row
Walk and (can usually be walked along the perpendicular direction of the center line with treating direction finding optical device 7), when the second light of the first mark rod 3
When receiving unit detects optical signal, show that now the first mark rod 3 is complete with treating that the center line of direction finding optical device 7 is overlapped
Into initial alignment.Now control the automatic travelling device stop motion.
Further, in order to ensure the accuracy being aligned, it can also be provided with first mark rod 3 luminous single
Member, the luminescence unit can outgoing it is parallel with the line of the first mark rod 3 and the second mark rod 4 or overlap it is coloured swash
Light, the 3rd light receiving unit is provided with the centerline for treating direction finding optical device 7, described when aligned to treat direction finding optics
The 3rd light receiving unit in equipment 7 can receive the laser of the luminescence unit outgoing on first mark rod 3.
Further, the antenna substrate is foldable design, when needing to carry out direction finding, the antenna substrate expansion；
