BENGALURU: State-run defence electronics major Bharat Electronics Limited (BEL) has signed a memorandum of understanding with space technology startup Bellatrix Aerospace to jointly design, develop and manufacture satellite systems and payloads, with a focus on the emerging very low Earth orbit (VLEO) regime.“The agreement aims to combine BEL’s experience in mission-critical electronics and defence payloads with Bellatrix’s expertise in satellite propulsion and subsystems to develop next-generation satellite platforms suited for VLEO operations,” BEL said Thursday.VLEO refers to orbital altitudes below traditional low Earth orbit, typically between about 150 km and 450 km above the Earth. Satellites operating in this region can offer higher-resolution imaging, lower communication latency and reduced launch costs, but require advanced propulsion systems to counter atmospheric drag.Under the partnership, the two companies plan to develop integrated satellite solutions that can support both strategic and civilian space missions. The collaboration is expected to strengthen indigenous capabilities in satellite platforms designed for VLEO operations.BEL said the tie-up reflects a broader effort to combine the manufacturing depth of established public sector firms with the agility and innovation of emerging deep-tech startups in the space sector.“BEL has decades of experience in developing advanced electronics, radars and communication systems for defence and strategic programmes. Bellatrix Aerospace, headquartered in Bengaluru, specialises in electric and green propulsion systems for satellites,” BEL said.The memorandum was exchanged between BEL general manager Rashmi Kathuria and Bellatrix Aerospace CEO and chief technology officer Rohan M Ganapathy.Representatives from both organisations said the partnership is expected to accelerate innovation and support the development of indigenous satellite systems tailored for next-generation space missions.
