초록

Innovative new methods in connection with lighter-than-air (LTA) free floating platforms, of facilitating legal transmitter operation, platform flight termination when appropriate, environmentally acceptable landing, and recovery of these devices are provided. The new systems and methods relate to rise rate control, geo-location from a LTA platform including landed payload and ground-based vehicle locations, and steerable recovery systems.

1. A method comprising: determining a location of a target balloon;determining locations of one or more neighbor balloons relative to the determined location of the target balloon, wherein the target balloon comprises a communication system that is operable for data communication with at least one of the one or more neighbor balloons;determining a desired movement of the target balloon based on the determined locations of the one or more neighbor balloons relative to the determined location of the target balloon, wherein the desired movement of the target balloon comprises a desired horizontal movement of the target balloon; andcontrolling the target balloon based on the desired movement of the target balloon, wherein controlling the target balloon based on the desired movement of the target balloon comprises controlling an altitude of the target balloon based on the desired horizontal movement of the target balloon. 2. The method of claim 1, wherein controlling the altitude of the target balloon based on the desired horizontal movement of the target balloon comprises: determining that the desired horizontal movement of the target balloon can be achieved by exposing the target balloon to ambient winds of a particular velocity;determining that ambient winds of the particular velocity are likely to be available at a particular altitude; andadjusting the altitude of the target balloon to attain the particular altitude. 3. The method of claim 1, wherein the target balloon and one or more neighbor balloons are high-altitude balloons. 4. The method of claim 1, wherein the target balloon and one or more neighbor balloons are part of a mesh network of balloons. 5. The method of claim 4, further comprising identifying any balloons in the mesh network that are within a predefined distance from the target balloon as the one or more neighbor balloons. 6. The method of claim 4, further comprising identifying any balloons in the mesh network that are within a communication range of the target balloon's communication system as the one or more neighbor balloons. 7. The method of claim 1, wherein the desired movement of the target balloon comprises a desired direction of movement. 8. The method of claim 1, wherein the desired movement of the target balloon comprises a desired velocity. 9. The method of claim 1, wherein the desired movement of the target balloon comprises a desired distance of travel in a desired direction. 10. The method of claim 1; wherein the communication system comprises a radio frequency (RF) communication system. 11. The method of claim 1, wherein the target balloon comprises an airfoil. 12. The method of claim 1, further comprising: determining a location of at least one of the balloons with respect to a geographic border; andmaking a flight termination decision based at least in part on the determined location with respect to the geographic border. 13. The method of claim 12, wherein the determined location with respect to the geographic border comprises a determined protective distance from an international border. 14. A non-transitory computer readable medium having stored therein instructions executable by a computing device to cause the computing device to perform functions, the functions comprising: determining a location of a target balloon;determining locations of one or more neighbor balloons relative to the determined location of the target balloon, wherein a desired movement of the target balloon comprises a desired horizontal movement of the target balloon; andcontrolling the target balloon based on the desired movement of the target balloon, wherein controlling the target balloon based on the desired movement of the target balloon comprises controlling an altitude of the target balloon based on the desired horizontal movement of the target balloon. 15. The non-transitory computer readable medium of claim 14, wherein the target balloon comprises a communication system that is operable for data communication with one or more other balloons in a mesh network of balloons, and wherein the functions further comprise identifying a plurality of balloons in the mesh network of balloons as the plurality of neighbor balloons. 16. The non-transitory computer readable medium of claim 14, wherein controlling the target balloon based on the desired movement of the target balloon comprises controlling an altitude of the target balloon. 17. A balloon, comprising: a communication system operable for data communication with one or more other balloons in a mesh network of balloons; anda controller coupled to the communication system, wherein the controller is configured to:(a) determine the balloon's location;(b) determine locations of one or more neighbor balloons relative to the balloon's determined location, wherein the one or more neighbor balloons are in the mesh network of balloons; and(c) determine a desired movement of the balloon based on the determined locations of the one or more neighbor balloons relative to the balloon's determined location, wherein the desired movement of the balloon comprises a desired horizontal movement of the balloon; and(d) control the target balloon based on the desired movement of the target balloon by controlling an altitude of the target balloon based on the desired horizontal movement of the target balloon. 18. The balloon of claim 17, further comprising: an altitude-control system that is operable to adjust an altitude of the balloon, andwherein the controller is configured to control the altitude-control system based on the desired horizontal movement of the balloon. 19. The balloon of claim 17, wherein the controller is configured to determine the balloon's location using a satellite-based positioning system. 20. The balloon of claim 17, wherein the controller is configured to determine the locations of the one or more neighbor balloons based on information received through the communication system. 21. The balloon of claim 17, further comprising: a transceiver, configured and arranged to communicate at least with a ground station. 22. The balloon of claim 21, wherein the transceiver is further configured and arranged to broadcast balloon data, wherein the balloon data comprises position information and corresponding time information. 23. The balloon of claim 21, wherein the transceiver is configured and arranged to operate on a selected one of a plurality of frequencies. 24. The balloon of claim 23, wherein the selected one of the plurality of frequencies is selected on the basis of a location within a determined geographic area. 25. The balloon of claim 23, wherein the determined geographic area is determined at least in part based on broadcast regulations governing at least a portion of the geographic area.
