Method of communication link acquisition using search pattern
摘要
說明書
After the designations are determined, the secondary device initiates a secondary search pattern using the second optical system 250 of the secondary device while the primary device transmits a beacon beam 24. The secondary search pattern is a series of frame positions forming an outward spiral that are ordered in increasing distance from a starting frame position. The one or more processors 210 of the secondary device may determine the starting frame position based on a best estimate of the location of the first optical system of the primary device. In particular, the starting frame position may be where a frame captured by the secondary device may be centered on the best estimated location.
The series of frame positions of the secondary search pattern may be arranged at intervals from the starting frame position in relation to an estimated misalignment, such as, for example, double the estimated misalignment or more or less. For example, the estimated misalignment may be estimated to be 0.30 degrees, and the series of frame positions of the secondary search pattern may be arranged at approximately 0.60 degrees intervals.
