Claim:
1. A computer-implemented method comprising: determining that an aerostat is located within a first atmospheric layer, wherein a first wind-velocity measure is indicative of wind velocity in the first atmospheric layer, determining an altitude of an atmospheric layer boundary between the first atmospheric layer and a second atmospheric layer, wherein a second wind-velocity measure is indicative of wind velocity in the second atmospheric layer, and wherein the second wind-velocity measure differs from the first wind-velocity measure by at least a threshold amount; determining a desired location for the aerostat; and during at least a portion of a flight towards the desired location, causing, by a controller, the aerostat to traverse back and forth across the atmospheric layer boundary while remaining within a predetermined vertical distance from the atmospheric layer boundary in order to achieve a desired horizontal trajectory.
