About
The CHORUS-01 is a versatile deployable antenna system designed for CubeSats, offering several configurations to meet diverse mission needs. The CHORUS-01-LP features linear polarization with 2x dipoles, supporting two independent frequencies within the 150 – 930 MHz range, and is suggested for 1U-2U-3U CubeSats. The CHORUS-01-CP provides circular polarization with a turnstile configuration, one independent frequency, and the same frequency range. For more complex requirements, the CHORUS-01-M offers linear polarization with 4x monopoles, supporting four independent frequencies, while the CHORUS-01-MD combines 2x monopoles and 1x dipole for three independent frequencies. All versions boast a bandwidth of 20dB, typical VSWR 0 dBi, and operate on a 3.3/5 V voltage supply with an I2C interface. The system is designed for reliability with a dual redundant deployment system, redundant power lines, and deployment feedback on each antenna element. It offers easy integration with resettable HDRM, multiple apertures for testing, and is compatible with platforms from 1U to 16U, allowing for top solar panel integration. Customization options include configurable UHF or VHF bands, customizable deployment sequences, and custom mounting holes.
