ORB-12 Strider [OrbAstro]
ORB-12 Strider is a 12U CubeSat built by OrbAstro to test a propulsion system for Aliena-Aurora and many internally developed subsystems.
Orbital Astronautics Ltd (OrbAstro), a satellite and in-orbit service provider, has signed a contract with Aliena to fly its AA Multi-modal all-electric AOCS propulsion system onboard an OrbAstro ORB-12 (12U-class satellite) scheduled for launch in September 2022.
The ORB-12 Strider mission will carry a variety of payloads for in-orbit testing and demonstration, the primary of which will be the Aliena-Aurora (AA) propulsion system.
Aliena has collaborated with Aurora Propulsion Technologies of Finland to develop a multi-modal attitude and orbit control system (AOCS). The propulsion segment will include Aliena's MUlti-Staged Ignition Compact (MUSIC) Hall thruster and Aurora's ARM resistojets, which will share a common back-end architecture for propellant, electronic control, and fluidics.
The AA multi-modal all-electric AOCS propulsion system will allow customers with the most stringent mission requirements to benefit from the MUSIC Hall thruster's low-thrust-high-impulse mode of operation as well as the ARM resistojets' high-thrust-low-impulse mode of operation. This system streamlines the propulsion architecture, enabling dual mode propulsion in a compact and integrated product for formation flying satellite operations and advanced operations that rely on propulsion as an enabler.
Aside from the AA AOCS payload, OrbAstro will be testing a number of internally developed subsystems on the satellite, some of which are new and some of which are second or third generation, including:
