Methods and systems are disclosed herein that may help to provide location-aware caching and/or location-specific service profiles in a balloon network. An exemplary method may be carried out by a balloon that is at a location associated with the first geographic area in a balloon network that includes a plurality of defined geographic areas, and may involve: (a) determining that a location-aware cache of a balloon should be updated with user-data associated with the first geographic area; and (b) in response to determining that the location-aware cache should be updated: (i) sending a location-aware cache-update request; (ii) receiving, as a response to the location-aware cache-update request, user-data that corresponds to the first geographic area; and (iii) storing the user-data that corresponds to the first geographic area in a location-aware cache of the balloon.

Exemplary embodiments may involve hierarchical balloon networks that include both optical and radio frequency links between balloons. An exemplary network system may include: (a) a plurality of super-node balloons, where each super-node balloon comprises a free-space optical communication system for data communications with one or more other super-node balloons and (b) a plurality of sub-node balloons, where each of the sub-node balloons comprises a radio-frequency communication system that is operable for data communications. Further, at least one super-node balloon may further include an RF communication system that is operable to transmit data to at least one sub-node balloon, where the RF communication system of the at least one sub-node balloon is further operable to receive the data transmitted by the at least one super-node balloon and to transmit the received data to at least one ground-based station.

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.

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.
摘要:
A balloon that includes an envelope with a gas contained within the envelope, as well as a payload connected to the envelope wherein the envelope has a first portion that has a first absorptive or reflective property with respect to allowing solar energy to be transferred to the gas within the envelope, and a second portion that has a second absorptive or reflective property with respect to allowing solar energy to be transferred to the gas within the envelope where the second absorptive or reflective property is different than the first absorptive or reflective property, and wherein the envelope is rotatable to allow a preferred ratio of the first and second portions of the envelope to be positioned facing the sun.

This disclosure relates to the use of a mobile device in connection with a balloon network. A disclosed method includes communicating with an antenna structure coupled to the housing of a mobile device. Additionally, the antenna structure may have an omnidirectional radiation pattern when the housing in a first position. The method may also include detecting a reconfiguration the housing of the mobile device. Further, the method also includes communicating with the antenna structure with the reconfigured housing. The antenna structure may have as directional radiation pattern when the housing in a second position. When in the second position the mobile device may be configured to communicate with a balloon network and when the mobile device is in the first position the mobile device may be configured to communicate with a cellular network.

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.

Methods and systems involving an incentivized recovery of balloon materials are disclosed herein. An example system may be configured to: (a) determine a landing location of a balloon, where the balloon has been configured to operate as a node in a balloon network; (b) detect a removal event corresponding to the balloon ceasing to operate as a node in the balloon network and descending to the landing location; and (c) in response to detecting the removal event, initiate a transmission of a recovery-assistance signal that is comprised of (i) location data corresponding to the landing location of the balloon and (ii) an indication of an incentive to recover the balloon.
