Fleet Space has spent $12 Million since 2015 on R&D to develop the world’s most advanced beam-steering antenna and to miniaturise its satellites’ communications payload. These make it possible to deliver its Nebula space-based data network using a 10kg nanosatellite where previously this level of connectivity was only possible with a 100kg satellite.
The company, which has already launched four nanosatellites, has applied for a $5 million grant under the Department of Industry, Science, Energy and Resources’ Modern Manufacturing Initiative (MMI) to help it make the jump. Fleet Space plans to build a new factory with more than double the space for R&D and manufacturing and has partnered with the University of Adelaide’s Institute of Photonics and Advanced Sensing, local company Redarc Electronics, Hawker Richardson in Melbourne and NSW-based Lintek to build the industrial capability to manufacture these nanosatellites in Australia.
The Nebula service for utilities, mining and energy companies uses satellites to connect sensors monitoring critical infrastructure such as remote mine sites, alternative energy sites, gas pipelines and rurally dispersed electricity pylons with central base stations, 24 hours a day. This also allows operators to conduct geological surveys and operate unmanned vehicles such as drones remotely from a proper control centre, rather than having to visit a distant, inaccessible site.
This is the Industrial Internet of Things (IIoT) and it’s transforming the ability of Australian companies to manage and control remote assets in real time, says Ms Tata Nardini. The full constellation of 140 nanosatellites could generate a lifetime revenue of $2.8 billion, she estimates.
The heart of Fleet Space’s 10kg Centauri-series satellites is its Nebula System, consisting of the smart, lightweight, low-power communications payload and antenna, ground-based Portal satellite modem and the Nebula Network Management System. The company designs all of these, including the advanced on-board Artificial Intelligence system that manages them, itself in Adelaide. However, it is forced to get the antenna and some of the complex electronics manufactured by space-qualified specialist suppliers in Switzerland.
In order to achieve seamless global coverage, the company needs a constellation of 140 satellites in Low Earth Orbit (LEO). Up to 50 will need to be replaced each year due to the rate of orbital decay associated with LEO as well as battery and solar panel degradation. A fifth satellite in Fleet Space’s constellation, Centauri 3, will be launched from New Zealand in just days, with two more scheduled for launch this year and 16 in 2022-23.
