We discuss various methods for acquiring optical links in space using a dedicated acquisition sensor. Statistical models are developed and simple analytical equations derived that compare the performance between a single- and dual-spiral scan approach as well as between sequential and parallel acquisition of link chains. Simple derived analytical equations allow relating essential search parameters such as track width, variance of the uncertainty distribution, capture radius, and scan speed to…

Impact of spectral noise shape and correlations of laser beam jitter on acquiring optical links in space.

We investigate how the probability of acquiring an optical link between a scanning and a target spacecraft depends on the spectral shape, power, and dimensionality of the beam jitter, as well as on…

Laser link acquisition demonstration for the GRACE Follow-On mission.

An inter-satellite laser link acquisition scheme for GRACE Follow-On is experimentally demonstrated, which optimizes the alignment between beams to allow a smooth transition to differential wavefront sensing-based auto-alignment.

Beaconless satellite laser acquisition - modeling and feasability

A detailed model of the acquisition process is developed and used to show that a diffraction-limited beam can be used for acquisition under some circumstances involving benign vibration environments, and the same methodology is used to determine an optimal beam divergence in other cases.

Acquisition time calculation and influence of vibrations for microsatellite laser communication in space

The time needed to finish the acquisition process and start tracking is examined, including the distribution function of satellite position, the size of the uncertainty area, the number of possible satellite positions, and the detection ability of a CCD.

Acquisition system for microsatellites laser communication in space

Optical communications is a very complex task between satellites because of the small laser beam divergence and the large distance. Also, the vibrations of the satellites due to satellite internal…
