CHORUS deployable antennas are configurable UHF or VHF antennas for CubeSats ranging from 1U to 16U, featuring linear double-dipole or turnstile layouts and a triple-redundant deployment system.
CHORUS Deployable Antenna
CHORUS deployable antennas are configurable UHF or VHF antennas for CubeSats ranging from 1U to 16U, featuring linear double-dipole or turnstile layouts and a triple-redundant deployment system.
Description
CHORUS deployable antennas are designed for CubeSat platforms, offering full configurability in either UHF or VHF frequency bands. They support various form factors, from 1U up to 16U, and can be configured with linear double-dipole or turnstile layouts. The antennas are highly modular and adaptable to different mission requirements. A key feature is their reliable operation, ensured by a triple-redundant deployment system. This system incorporates two fully independent and separately controllable circuits (primary and secondary), enhancing the robustness and success rate of antenna deployment in space.
