Next-generation digital phased array satcom ground stations.
Over the next decade, tens of thousands of small satellites will be launched into non-geostationary orbits, mostly deployed as constellations. All these satellites need to communicate with the ground at specific, pre-allocated and shared radio frequency bands, increasing downlink capacity from gigabits per second (Gbps) to terabits per second (Tbps).
Ground stations are the epicentre and bottleneck of any space system. A ground station typically comprises a parabolic dish that receives data from a single spacecraft as it passes overhead. The ground station market is aggressively expanding capacity now to cater to the small satellite constellations’ real-time connectivity requirements.
Transitioning from parabolics to digital phased array technologies will enable the industry to scale quickly to meet the demands of satellite constellations. Our solution, a cryogenically-cooled digital phased array, can support thousands of electronically-steered beams simultaneously for transmission tracking and/or adaptive nulling.
This system is a cryogenically-cooled phased array utilising software defined radio tracking and nulling technology, as a satellite ground station service. This creates enormous flexibility and additional degrees of freedom in the availability of data and functionality of space-derived downstream services.
We have several patents related to the system’s core components.
We are exploring options to establish a joint venture with an ‘anchor’ partner to produce systems and operate them as a service. Interested investors are encouraged to contact CSIRO’s Commercialisation team to explore potential investment.
