Very Low Earth Orbit (VLEO) Spacecraft Operations

P2.27


Project Leaders: Patrick Wang – Space Ops Australia

Participants: Space Ops Australia, The University of Sydney

Very Low Earth Orbit (VLEO) is a region of space above the Kármán line and up to The International Space Station at approximately 450km altitude. This region is a challenge to operate in due to atmospheric effects limiting the total lifespan of a typical satellite.

This project will investigate the development of a purpose-built attitude and orbit control system (AOCS) for operation in VLEO to create new mission opportunities, improving data products and communication services. The operational advantage of closer proximity to ground and high revisit rates will bring enhanced commercial products and capabilities to consumers, expanding the ease and access to space.

The new AOCS will bring innovation on orbital control in regions of significant atmospheric density, coupling new propulsion methods and attitude manoeuvring concepts for sustainment of new small satellite operations.
