    Abstract: The positions of balloons in a communication network of balloons, such as a mesh network of high-altitude balloons, may be adjusted relative to one another in order to try to maintain a desired network topology. In one approach, the position of each balloon may be adjusted relative to one or more neighbor balloons. For example, the locations of a target balloon and one or more neighbor balloons may be determined. A desired movement of the target balloon may then be determined based on the locations of the one or more neighbor balloons relative to the location of the target balloon. The target balloon may be controlled based on the desired movement. In some embodiments, the altitude of the target balloon may be controlled in order to expose the target balloon to ambient winds that are capable of producing the desired movement of the target balloon.

    Abstract: A balloon may include an optical-communication component, which may have a pointing axis. A pointing mechanism could be configured to adjust the pointing axis. The optical-communication component could be operable to communicate with a correspondent balloon via a free-space optical link. For example, the optical-communication component could include an optical receiver, transmitter, or transceiver. A positioning system could be configured to acquire a first location, which could be based on the location of the balloon. A controller could be configured to acquire a second location, which could be based on a location of the correspondent balloon. The controller may determine an approximate target axis based on the first location and the second location. The controller may control the pointing axis of the optical-communication component within a scanning range based on the approximate target axis to establish the free-space optical link with the correspondent balloon.
