    Abstract: The technology relates to free-space optical communication systems that correct for errors in tracking and pointing accuracy to maintain connection integrity. Such systems can both proactively and reactively correct for errors in tracking performance and pointing accuracy of terminals within the system. An aspect includes receiving information indicative of at least one external disturbance associated with a communication device. A determination is made for a proactive estimation indicative of a first error associated with an effect of the at least one external disturbance at a current timestep. A determination is made for a reactive estimation indicative of a second error associated with the effect of the at least one external disturbance at a previous timestep. A final control signal is determined based on the proactive estimation and the reactive estimation. A controller is able to actuate an optical assembly of the communication device based on the determined final control signal.

    Abstract: The disclosure provides for a communication system that includes one or more sensors and one or more processors. The one or more processors are configured to receive, during a first timeframe, a first indication of an error rate of a communication link, a second indication of an amount of received power at a remote communication system, and one or more measurements related to the state of the communication system. The one or more processors are then configured to estimate a plurality of disturbance values to the communication system according to the one or more measurements and the second indication. Each disturbance value is associated with a set of components of the communication system. The one or more processors are configured to adjust a beam divergence of a beacon beam or a communication beam transmitted from the communication system based on the plurality of disturbance values and the first indication.

    Abstract: The disclosure provides for a method for reacquiring a communication link between a first communication device and a second communication device. The method includes using one or more processors of the first communication device to receive historical data related to the first communication device and an environment surrounding the first communication device. The one or more processors are then used to determine one or more trends in the historical data related to fading of the communication link. Based on the one or more trends, the one or more processors are used to determine a starting time and an initial search direction for a search for the communication link. The one or more processors then execute the search at the starting time from the initial search direction.

    Abstract: Aspects of the disclosure provide a system comprising a first optical communications terminal. The first optical communications terminal comprising a telescope comprising one or more lenses; a movable photonics integrated circuit (PIC) assembly positioned relative to the telescope comprising an optical phased array (OPA); and one or more processors configured to move the moveable PIC assembly; wherein the moveable PIC assembly is configured to move by at least one of i) rotating, or ii) moving along a path, and iii) moving closer to or further from a telescope of the first optical communications terminal.

    Abstract: The disclosure provides a method for adjusting an optical link alignment of a first communication device with a remote device. The method includes transmitting or receiving an optical signal; receiving one or more measurements of at least one environmental factor at the first communication device or the remote device; and receiving or detecting an apparent amount of alignment of the optical signal. Then, by one or more processors of the first communication device, determining an estimated error attributable to optical cross coupling and an actual amount of alignment of the optical signal based on the apparent amount of alignment and the estimated error. Next, adjusting the first communication device based on the actual amount of alignment to correct for optical cross coupling.
