Each CubeSat employs a unique antenna, called a Vector Sensor Antenna (VSA), to measure all six electromagnetic degrees of freedom of incoming HF radiation via a combination of loop, dipole and monopole antennas. The VSA payload stows into a 13.7 cm by 8.7 cm by 11.5 cm volume within the 6U spacecraft, and through a series of deployments, makes a 4 m by 4 m by 2.3 m antenna array. The relatively large antenna element deployment from such a small initial volume is achieved using fiberglass composite tape springs which unroll to form the antenna elements. These tape springs fall into a class of structural elements called High Strain Composites (HCS), which are becoming more commonly used in space missions. This paper describes the development, testing and integration of the AERO-VISTA VSA payload second generation prototype.
