Details
The Global Navigation Satellite System Radio Occultation (GNSS-RO) technique is important for atmospheric observation. CubeSats offer a low-cost alternative, yet their small size restricts antenna performance.
This study introduces a 0.5-meter deployable antenna that fits inside a 1U (10 cm × 10 cm × 10 cm) CubeSat. Deployment tests show geometric stability, and the measured directivity reaches 13.07 dBi, representing a 61 % improvement over a commercial GNSS-RO patch antenna.
