Gilmour Space Technologies was founded as a Singapore-based venture in 2012 and later established its Australian operations around 2013, with the primary headquarters now located in Yatala, Queensland, near the Gold Coast. The company’s core mission is to offer affordable and sovereign space access, focusing on delivering small satellite launch services using Australian-developed technologies, especially its three-stage Eris orbital launch vehicle, designed to place payloads into low Earth orbit.

From its early days, Gilmour Space demonstrated innovation through hybrid propulsion systems and experimentation with 3D-printed fuel, notably launching Australia’s first privately developed hybrid rocket in 2016. The company’s aspirations span multiple key focus areas: not only satellite launch services via the Eris rocket, but also satellite bus platforms (like the modular G-Sat for ride-sharing payload deployments), advanced propulsion systems combining hybrid and liquid-fueled stages, and the creation of infrastructure such as its Bowen Orbital Spaceport, Australia’s first licensed commercial orbital launch facility

Strategic alliances and collaborations have been central to Gilmour Space’s progress. In 2018, the company signed a reimbursable Space Act Agreement with NASA to further space research, development, and educational initiatives. A statement of strategic intent with the Australian Space Agency followed in 2019, underscoring its commitment to boosting Australia’s sovereign space capabilities. The company’s investor base features prominent names like Blackbird Ventures, Main Sequence Ventures, and internationally Fine Structure Ventures, along with backing from superannuation funds like HESTA, Hostplus, and NGS Super. On the commercial front, Gilmour has secured launch contracts, such as with Space Machines Company for a 35 kg payload to orbit, showcasing its services in payload deployment for other New Space firms. Additional technical and manufacturing support comes from partners, including RUAG Space and Ansys, aiding in avionics, navigation, and systems modeling.

Gilmour Space Technologies offers a distinctive suite of products and services woven together in a seamless, end-to-end framework that spans from satellite hardware to launch execution—all built with an emphasis on Australian innovation and sovereignty. At the forefront of their offering is the Eris orbital launch vehicle, a three-stage rocket purpose-built to deliver up to approximately 300 kg of payload into low Earth orbit, or around 215 kg into sun-synchronous orbit. Its hybrid-propulsion architecture combines proprietary solid fuel and liquid oxidizer engines that power the first two stages, while a precisely controlled, liquid-fueled third stage refines orbital insertion. The Eris design emphasizes manufacturability, operational simplicity, and competitive pricing, underpinned by their own avionics and launch software.

Complementing the spacecraft launcher is ElaraSat, Gilmour’s modular 100-kg small-satellite bus, also known as G-Sat. Designed for ride-sharing and flexibility, this platform enables payloads ranging up to ~125U to be stacked or integrated as single or multiple units. The satellite bus has already demonstrated its capability in orbit, most notably with the MMS-1 mission, carrying a hyperspectral sensor developed in partnership with CSIRO and successfully launched aboard a SpaceX Transporter ride-share mission.

Their service offerings include fully integrated orbital launch services for commercial and governmental small satellite operators, including dedicated launches via Eris as well as rideshare arrangements to reduce customer cost by sharing payload space. Gilmour also couples these launch services with its own satellite platforms, offering a true turnkey “launch plus spacecraft” solution. Gilmour has forged robust collaborative partnerships to enhance its offerings. The company teamed up with Exolaunch, leveraging their rideshare and small-sat deployment infrastructure to expand Eris’s deployment capabilities and provide in-space transportation services. They have also joined forces with Inmarsat, utilizing its InRange satellite-based telemetry system to ensure real-time launch data coverage without needing extensive ground station infrastructure. Gilmour operates the Bowen Orbital Spaceport, Australia’s first commercial orbital launch facility, located in North Queensland. This uniquely positioned spaceport allows direct launch access into a wide range of orbits, further reinforcing the company’s complete vertical integration.

Gilmour Space Technologies embodies Australia’s leap from being a participant in the global space industry to becoming a true enabler of sovereign access to orbit. By advancing hybrid propulsion systems, developing versatile small-satellite platforms, and establishing the nation’s first licensed orbital launch site, the company has not only created a pathway for domestic satellite operators but also positioned Australia as a competitive force in the international launch market. Its blend of technological innovation, strategic partnerships, and commitment to affordable, sustainable space access underscores a contribution that extends beyond rockets and satellites; it represents the forging of a new era for Australia’s role in space exploration and commercialization.
