| Tab | Tcb | Tdb | x | y | z |
| Tab1 | Tcb1 | Tdb1 | x1 | y1 | z1 |
| Tab2 | Tcb2 | Tdb2 | x2 | y2 | z2 |
| Tab3 | Tcb3 | Tdb3 | x3 | y3 | z3 |
| Tab4 | Tcb4 | Tdb4 | x4 | y4 | z4 |
| ... | ... | ... | ... | ... | ... |
It should be noted that above-mentioned default time set and the mapping relations of coordinate set are pre- to be stored to the first movement

Specifically, if feedback signal includes the time point that the second mobile terminal sends feedback signal, the first movement
For terminal when receiving the feedback signal, the first mobile terminal records receive the time of the feedback signal, are then based on connecing again
The time difference of the time and the time point of feedback signal carrying of the feedback signal are received, the first mobile terminal and second can be obtained
The distance of mobile terminal.If being provided with 3 receiving points on the first mobile terminal, this 3 receiving points are respectively received the feedback letter
Number time it is different, therefore, the distance of this 3 receiving points to the second mobile terminals is also different.It is each according to this 3 receiving points
From the coordinate position of the distance to the second mobile terminal and this 3 receiving points, it may be determined that the second mobile terminal is relative to
The orientation of one mobile terminal.For example, as shown in figure 3, a, d and c point are 3 fixed receiving points on the first mobile terminal, a, d
A fixed face is formed with c points.E is the second mobile terminal, and the distance that a, d and c arrive e points respectively is Lae、Lde、Lce.So root
According to Lae、Lde、Lce, the coordinate of a points, the coordinate of d points, the coordinate of the coordinate of c points and e points e points can be calculated relative to a, d
The orientation in fixed face is formed with c points.The orientation is relative bearing of second mobile terminal relative to the first mobile terminal.
