BEL and Bellatrix Aerospace Sign MoU to Develop Indigenous VLEO Satellite Technologies
Bharat Electronics Limited (BEL) and Bengaluru-based startup Bellatrix Aerospace signed a Memorandum of Understanding (MoU) to jointly design, develop, and manufacture satellite systems and payloads for Very Low Earth Orbit (VLEO) operations.
The partnership combines BEL's decades of experience in advanced electronics and mission-critical defence payloads with Bellatrix Aerospace's innovative satellite propulsion technology — specifically its air-intake electric propulsion system.
The collaboration aims to build indigenous VLEO satellite capabilities that have applications in high-resolution Earth observation, secure communications, and defence surveillance.
The MoU is part of India's broader push to commercialise space technology under the IN-SPACe regulatory framework and operationalise the Indian Space Policy 2023.
Bharat Electronics Limited (BEL): Profile and Defence Role
BEL is a Navratna Defence Public Sector Undertaking (DPSU) under the Ministry of Defence, established in 1954. It is India's primary manufacturer of advanced electronic systems for defence and strategic applications — including radar systems, communication equipment, electronic warfare systems, and satellite ground systems.
BEL brings the manufacturing scale, quality systems, and defence-grade reliability that Bellatrix Aerospace's novel propulsion technology needs to transition from prototype to deployable satellite systems.
Very Low Earth Orbit (VLEO): Definition and Strategic Significance
VLEO refers to orbital altitudes between approximately 100 and 450 kilometres above Earth's surface — lower than the conventional Low Earth Orbit (LEO) band of 400–2,000 km. VLEO satellites have distinct advantages: higher resolution imaging, lower signal latency, and smaller antenna requirements for ground communication. However, they face engineering challenges: significant atmospheric drag requires continuous propulsion to maintain orbit.
The BEL-Bellatrix MoU specifically targets VLEO — a frontier orbital regime with significant defence and commercial applications that India currently lacks indigenous capability to exploit.
IN-SPACe and India's Private Space Ecosystem
The Indian National Space Promotion and Authorisation Centre (IN-SPACe) is an autonomous body under the Department of Space (DoS), established in June 2020 to enable private sector participation in India's space economy. It functions as a single-window regulator and promoter for Non-Governmental Entities (NGEs) in space activities. The Indian Space Policy 2023 provided the formal framework for industry participation in satellite manufacturing, launch services, and ground systems.
Key Details
- IN-SPACe mandate: promote, enable, authorise, and supervise space activities of NGEs (private companies, startups, academia).
- Indian Space Policy 2023: delineates roles — ISRO focuses on R&D and national missions; NSIL (NewSpace India Limited) commercialises ISRO technology; private sector handles commercial satellites and launch vehicles.
- FDI in space sector: raised to 74% automatic route (for satellite manufacturing and operations) — further liberalised from the earlier 49% ceiling.
- India Space Fund: Rs 1,000 crore VC fund announced in Union Budget 2024 for space startups.
- Bellatrix Aerospace: founded 2015, IISc alumni startup; raised Series A funding; IN-SPACe authorised; first satellite launch targeted 2026.
The BEL-Bellatrix MoU is a textbook example of the collaborative model envisioned by IN-SPACe: a defence DPSU partnering with a private space startup to develop indigenous dual-use (civilian + defence) satellite capability within the Indian Space Policy framework.
- BEL: Navratna DPSU under Ministry of Defence; established 1954; revenue ~Rs 20,000 crore (FY2025).
- Bellatrix Aerospace: founded 2015; Bengaluru-based; IISc alumni startup; IN-SPACe authorised entity.
- VLEO altitude: 100–450 km (vs. LEO: 400–2,000 km).
- Bellatrix propulsion innovation: Air-Breathing Electric Propulsion (ABEP) — uses atmospheric air as propellant, enabling extended VLEO operations.
- IN-SPACe: established June 2020 under Department of Space; India's single-window space regulator for private sector.
- Indian Space Policy 2023: formal framework separating ISRO (R&D), NSIL (commercialisation), and private sector (commercial) roles.
- FDI in satellite manufacturing: 74% via automatic route (liberalised 2024).
- India Space Fund: Rs 1,000 crore (Budget 2024) for space startups.
- VLEO imaging advantage: ~2.5x better resolution vs. LEO for the same sensor at lower altitude.
