OrbAstro (Orbital Astronautics Ltd) is a space technology company focused on compressing the upfront cost and lead-time to get from business idea to revenue generation, for companies utilising satellites.


OBC contains an Ultrascale+ based OBC (4GB RAM, 256GB high-speed storage), full ADCS, reaction wheel controls, magnetorquer controls, star-trackers, camera interfaces, full SDR S-/X-band (up to 150Mbps), GPS, optical data link control & processing, and Kintex FPGA for heavy data-processing and AI applications. The baseline system provides a total processing power exceeding 2 TFLOPs. Fault tolerance (SEU and SEL protection) implemented on both hardware and software. Most of the systems are based on TMR for fault-tolerant logic. EDAC is implemented on all memory units.

We have developed high-gain X-band and Ka-band reflectarray antennas for use on the OrbAstro ORB-6 class satellites (~10kg) and larger. These antennas mirror the effectiveness of dish antennas in a lighter, flatter design. They also offer wider bandwidth and greater efficiency than patch antenna arrays. Coupled to our Ultrascale+ based SDRs, these RF systems are compelling. They will be operational in orbit from October onwards. The example shown is our 29.3dBi X-band variant associated with our ORB-50 class satellites (~100kg).
