Spherical Panoramic Image Payload Design for Stratospheric Ballooning

---

Abstract

The 2017 total solar eclipse inspired innovation in design and implementation in stratospheric ballooning techniques and payloads to fully document the unique near-space experience. The Arkansas BalloonSAT team, as part of the Eclipse Ballooning Project, designed and fabricated a spherical panoramic image payload using computer aided design (CAD) software to capture images of the eclipse from the high altitude balloon. The light, durable, and water resistant mount consisted of a polyurethane-coated UV-resin based enclosure that housed six Hero 4 Session GoPro cameras, and a relative inertial measurement unit (IMU) PCB equipped with GPS. The cameras’ lenses faced radially outward on the six faces of a cube. The IMU/GPS PCB system computed the absolute orientation of the cameras, which allows the time-lapse pictures to be stitched together into a relatively stable spherical video. The batteries for this system experienced a voltage drop during flight as the payload temperature dropped below -60 degrees Celsius resulting in an auto-shutdown procedure disabling the system before eclipse totality. Future designs for this model will include a temperature regulation or insulation system to prevent this voltage drop.
