Zero-pressure solar balloons, aka heliotropes, have become an attractive platform for atmospheric science and aero-seismology research as they provide a low-cost, long-duration areal platform for stratospheric infrasound research. In many instances, multi-balloon swarms provide a much-needed capability for simultaneous multi-point observations. For example, a single balloon does not provide the full picture for atmospheric gravity wave observations, often requiring multiple launches. Likewise, a single balloon sensor array is also undesirable for infrasound source detection due to the wavelength of infrasound forcing a single balloon array construction to be too large and cumbersome to implement. This is not the case for a muti-balloon array, with each balloon carrying one or two small infrasound microphones, since it is then possible to perform back azimuth event locations on infrasound signals. Back azimuth and source detection utilizing a multi-balloon array strongly depend on the lateral distance between each sensor. Due to variations in balloon and payload construction, the float altitude of these platforms can vary by several kilometers leading to large amounts of lateral drift from each other over the duration of the flight. This lateral drift limits the time from launch that a balloon array can be used to reliably find the back azimuth of a signal. To combat this drift, a solar balloon vent system is being developed and tested along with a LoRa-based communication and control system to minimize the vertical separation of a balloon array and, as a result, reduce the lateral drift between each balloon. This research discusses component design and integration, algorithm development, and system validation over several flights.
