Laser Communications: Transcelestial Powers Light-Speed Connectivity in NT
Transcelestial’s laser communications system shows how resilient, scalable connectivity can drive commercial impact in Northern Australia.
At this year’s Northern Territory Defence Week, a live technology demonstration offered a glimpse into the future of communications infrastructure—one where signal jamming is no longer a threat, and fibre-speed data transmission is possible without physical cables.
The centrepiece was CENTAURI, a proprietary laser communication system from Singapore-based deep tech startup Transcelestial. During the live test, two laptops joined a Google Meet call—one via standard Wi-Fi, the other through CENTAURI. When a jamming device disrupted all radio-based signals, the Wi-Fi laptop froze and dropped out. The CENTAURI connection remained uninterrupted.
This wasn’t just an impressive technical display—it was a clear business case for secure, high-speed connectivity in mission-critical sectors.
Laser Communications: Commercial-Grade Connectivity, No Cables Required
CENTAURI uses laser communications via free-space optical (FSO) technology, transmitting data through the air using light. That means it doesn’t rely on spectrum and is inherently immune to jamming and interception. With speeds of up to 40 Gbps, it delivers fibre-grade performance without the time and cost of laying physical infrastructure.
For industries operating in remote, complex, or high-security environments—such as defence, mining, energy, logistics, and telecommunications—this represents a step-change in capability. It provides immediate, secure and scalable data transmission, even in locations where conventional networks can’t reach or where interference is a risk.
CENTAURI isn’t an experimental solution—it’s a commercially deployed product already in use across Singapore, India, the Philippines, Malaysia, Taiwan, Indonesia, and Australia.
A Global Startup with Strategic Investors
Transcelestial was founded in 2016 by Rohit Jha and Mohammad Danesh. Today, the company is backed by a strong bench of strategic investors, including Airbus Ventures, In-Q-Tel, Wavemaker, SEEDS Capital, Kickstart Ventures, and Paspalis Capital—an early believer in the company’s regional potential.
Paspalis’s investment reflects a wider commitment to innovation-led economic growth in Northern Australia. As CENTAURI scales, its ability to strengthen sovereign capability and improve remote-area connectivity aligns with long-term infrastructure and development goals in the region.
For investors, Transcelestial represents a well-placed opportunity in a global growth market: high-throughput, low-latency connectivity for defence, enterprise, and public infrastructure.
Building a Space-Based Network
CENTAURI is just the beginning. Transcelestial is now developing a “Cloud in Space”—a low Earth orbit (LEO) satellite network that uses the same FSO technology to deliver fast, secure, non-spectrum-based internet globally.
Unlike conventional satellite internet systems that use radio frequencies (e.g. Starlink), this new architecture avoids congestion and interference entirely. The result: ultra-secure, non-jammable, and low-latency connectivity, ideal for governments, corporations, and communities requiring sovereign data assurance.
This space-based expansion offers massive potential for regional Australia, particularly where terrain or distance has made traditional network build-outs unviable.
Darwin: A Strategic Gateway for Innovation
The decision to demonstrate CENTAURI at NT Defence Week—and in Darwin specifically—is no coincidence. Northern Australia sits at the intersection of defence strategy, regional development, and connectivity demand.
The Darwin Innovation Hub (DIH) has been instrumental in enabling this convergence. Through its Landing Pad service, DIH offers soft-landing support for international startups entering the NT market. From strategic introductions to co-working spaces and advisory services, the DIH Landing Pad has helped startups like Transcelestial gain traction and navigate local networks with confidence.
For DIH, the CENTAURI demo underscores the region’s potential to be more than just a testbed. With the right support and investment, Darwin can lead Australia in scaling emerging technologies that solve real infrastructure challenges.
It also reinforces the power of venture-backed innovation to drive long-term impact across industry, government, and community.
Enabling Growth Where It’s Needed Most
CENTAURI’s ability to maintain a live video feed under jamming conditions is more than a technical feat—it’s a commercial proof point. From emergency response to remote operations and national security, the demand for secure, fast, scalable communications are only increasing.
Transcelestial’s laser communications technology meets that need. It is ready now, cost-efficient, and designed to scale…
