If the determined level of confidence is less than the threshold level of confidence, the one or more processors 210 of the secondary device may move the second optical system 250 of the secondary device to a next frame position in the secondary search pattern 700 using the pointing hardware 260 and repeat the frame acquisition and beacon detection process described above. For instance, if the one or more processors 210b of the second communication device 200b determine that there is a 10% level of confidence that a beacon beam 24a is at the location captured from the starting frame position 0, then the second optical system 250b is moved to position 1 using pointing hardware 260b, the next frame position in the secondary search pattern 700.
The one or more processors 210 may be configured to rotate through every frame position in the secondary device until a beacon beam 24 is detected. After the last frame position of the secondary search pattern 700 is reached with no detection of the beacon beam 24 of the primary device, the one or more processors 210 of the secondary device is configured to repeat the secondary search pattern 700.
