摘要： Disclosed herein are embodiments of a balloon-based positioning system and method. In one example embodiment, a system includes a group of at least three balloons deployed in the stratosphere and a control system configured for: determining a first set of spatial relationships relating to the group; determining a second set of spatial relationships relating to at least a portion of the group and to a reference point; determining a position of the reference point relative to the earth; using the determined first set, the determined second set, and the determined position of the reference point relative to the earth as a basis for determining a position of a target balloon in the group relative to the earth; and transmitting the determined position of the target balloon relative to the earth.

摘要： Example methods and systems for determining failure modes of balloons within a balloon network are described. One example method includes: (a) determining at least one cohort balloon of a first balloon, where the first balloon is operating as part of a balloon network and where each cohort balloon shares at least one property with the first balloon, (b) determining at least one expected failure mode based at least in part on at least one failure of at least one cohort balloon, (c) determining a predicted failure mode of the first balloon based at least in part on the at least one expected failure mode, and (d) causing the first balloon to operate within the balloon network based at least in part on the predicted failure mode of the first balloon.
