It weighs about 15 kilograms and has the volume of a standard fridge.
While it may be sitting in a Canberra office overlooking Northbourne Avenue, if all goes to plan, come next year it will be launched into space, helping to manage air traffic control from above the ground.
Canberra satellite manufacturer Skykraft says it has completed work on a prototype of a spacecraft chassis that will help to launch a constellation of 210 satellites into orbit.
The constellation will be used to help monitor air traffic control operations across the globe, providing continuous coverage for planes flying at any altitude.
Skykraft managing director James Prior said the constellation would be connected with satellites on the ground.
"It will help to provide a seamless stream of data around the world," Mr Prior said.
"It takes out the need for ground-based infrastructure and antennas, and will be able to see over large stretches of water and the communication with the aircraft is the same."
Work on developing the chassis for the spacecraft has been under way by the Canberra team for several months.
Among the tests carried out have been vibration tests at Mount Stromlo, simulating what the chassis would go through as it's launched into space.
Mr Prior said it's hoped the constellation of satellites will lead to safety improvements for air traffic control operations across the world.
"There's some big efficiencies that can be made and it will be secure and instantaneous, so we don't have some of the problems associated with the disappearance of Malaysian Airlines flight MH 370," Mr Prior said.
"It won't prevent it from happening, but it would flag to the system at the point the aircraft went missing and where there would be anomalies."
It's hoped the constellation will be sent into orbit in June next year, with the launch happening overseas.
Further vibration tests will be conducted in coming months to ensure nothing breaks off the chassis upon the launch into space.
"A lot of work goes into how to put the constellation up and how it ensures that the satellites are always able to talk between themselves and adapt if there's any damage," Mr Prior said.
Skykraft received $1 million from the ACT government in September 2019 to help develop the constellation.
ACT Space Industries Minister Mick Gentleman said the completion of the prototype chassis was a major milestone for the project.
"This is one of many projects putting Canberra at the forefront of Australia's space industry," Mr Gentleman said.
