    摘要： Example embodiments may facilitate altitude control by a balloon in a balloon network. An example method involves: (a) causing a balloon to operate in a first mode, wherein the balloon comprises an envelope, a high-pressure storage chamber, and a solar power system, (b) while the balloon is operating in the first mode: (i) operating the solar power system to generate power for the balloon and (ii) using at least some of the power generated by the solar power system to move gas from the envelope to the high-pressure storage chamber such that the buoyancy of the balloon decreases; (c) causing the balloon to operate in a second mode; and while the balloon is operating in the second mode, moving gas from the high-pressure storage chamber to the envelope such that the buoyancy of the balloon increases.

    摘要： 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.

    摘要： 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.

    摘要： A balloon having an envelope and a payload positioned beneath the envelope. The envelope comprises a first portion and a second portion, wherein the first portion allows more solar energy to be transferred to gas within the envelope than the second portion. The balloon may operate in a first mode in which altitudinal movement of the balloon is caused, at least in part, by rotating the envelope to change an amount of the first portion that faces the sun and an amount of the second portion that faces the sun, and wherein the control system is further configured to cause the balloon to operate in a second mode in which altitudinal movement of the balloon is caused, at least in part, by moving a lifting gas or air into or out of the envelope.

    摘要： 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 controller could be configured to determine a predicted relative location of the correspondent balloon. The controller may control the pointing mechanism to adjust the pointing axis of the optical-communication component based on the predicted relative location so as to maintain the free-space optical link with the correspondent balloon.
