HEX20 has signed a strategic collaboration with Singapore based Transcelestial to deploy a next-generation optical communication network in orbit, leveraging HEX20’s DINK-N 50–100 kg class satellite platform.
As part of the partnership, Transcelestial’s laser-based inter-satellite communication (ISL) payloads will be integrated into HEX20’s DINK-N Earth Observation constellation. This architecture will enable high-speed data transfer directly between satellites, significantly enhancing the way large volumes of Earth observation data are processed and relayed, without reliance on repeated ground station passes.
The first two nodes of the satellite network is targeted for launch in 2027 and is designed to support the growing global demand for near real-time insights from space.
“This collaboration marks a significant leap towards building a future ready satellite network capable of processing and transmitting large volumes of data with low latency from orbit,” said Dr. Amal Chandran, Chief Executive Officer of HEX20. “By integrating high-speed optical inter-satellite links with a robust RF fail-safe, we are enabling near real-time data handling paving the way for faster, more resilient space operations.”
The partnership also underscores the strengthening India–Singapore space technology corridor, bringing together HEX20’s modular satellite platforms and Transcelestial’s advanced laser communication systems to address the needs of global commercial and defence missions.
HEX20 extends its sincere appreciation to IN-SPACe and Dr. Vinod Kumar for their continued support, particularly in enabling international collaborations. This engagement reflects the growing role of Indian space startups in delivering globally relevant missions and shaping next-generation space infrastructure.
As demand accelerates for faster, more reliable data delivery from orbit across Earth observation, communications, and security domains, the HEX20–Transcelestial collaboration positions optical networks as a critical backbone for the next generation of space systems, driving a shift toward smarter, more responsive, and globally connected space infrastructure.
