Arun Raj K M did a nice profile of HEX20, a Kerala-based space startup.
Here are the highlights from that story in English. These are translations made by Gemini. I’ve added a few links that could help you understand the backstories behind the names like Mayavi and Dinkan.
- News Anchor: Mayavi and Dinkan are the names of new satellites built by a Keralite startup. This is the next leap for HEX20, which successfully completed two CubeSat missions in a short period. Based in Thiruvananthapuram, this small startup is exploring new opportunities in the space market through the innovative concept of ‘CubeSat as a Service’.
- Arun Raj: Their business model helps other companies conduct in-orbit technology demonstrations using CubeSats. The satellite bus (chassis) and core technologies belong to HEX20, allowing clients to integrate their own experimental or observational payloads as needed. HEX20 opens up massive opportunities for companies aiming to execute complex space missions. Without the huge costs and complexities of building a full satellite from scratch, clients can evaluate their technology’s capabilities and refine their hardware at lower risk.
- HEX20 has launched two CubeSats into space so far: Nila last year, and KOYO (Kinetic Optical Yaw Observer) this past July. Both were launched aboard SpaceX Falcon 9 Transporter rideshare missions. KOYO was built for Taiwan’s National Central University.
- Dr. Manu Mohan (Tech Manager, HEX20): KOYO stands for ‘Kinetic Optical Yaw Observer’. It primarily carried payloads from Taiwan’s National Central University. As it orbits Earth, the satellite tumbles, so the initial payload was meant to measure its angular velocity or tumbling rate. We planned an operational lifespan of 6 months. According to UN guidelines, satellites in orbit must de-orbit within 25 years; at an altitude of 590 km, we expect it to naturally de-orbit in 5–6 years.
- Thomas C. Francis (Mechanical Engineer): For instance, KOYO is a 3U CubeSat measuring 300 mm x 100 mm x 100 mm. It gets deployed in space from inside a canister deployer. The first task is making sure it fits precisely into the deployer through accurate manufacturing. To withstand launcher vibrations and shocks, we conduct rigorous vibration and simulated space environment testing.
- Muhammed Saydali (Senior Electrical Engineer): We categorize our satellite buses into two main platforms based on mass and application: AX and NX. The NX platform accommodates satellites in the 20–50 kg range, whereas KOYO and Nila are built on the AX platform.
- Anamika A. Kamath (Electrical Engineer): The immediate upcoming mission is NILA-3, an In-Orbit Demonstration (IOD) testing a water-steam propulsion system developed by UK-based OOMSpace. That will launch within a few months this year. Following that are Mayavi and Dinkan. MAYA-V1 stands for ‘Multi Application Yearly Assimilated Vehicle 1’, which will form a series of satellite buses. DINK-N1 stands for ‘Direct Imaging Network Node 1’ and marks our entry into the 50 kg microsatellite class. We are targeting a late 2027 launch for these.
- Abhijith Sureshkumar (Ground Station Engineer): HEX20’s ground station is set up at the nearby Marine Engineering College. We currently operate two ground station setups capable of handling both UHF commercial and amateur bands. Since future missions like MAYA-V1 and DINK-N1 demand higher data rates, we are expanding our ground station capabilities to support higher frequency bands.
- Arun Raj: While many space startups keep mission data confidential, HEX20 stands out by making real-time KOYO telemetry available to the public via koyo.hex20.space.
- Shinjith George (Senior Electrical Engineer): We maintain a Class 8 cleanroom suited for integrating satellites up to 30 kg. Having finished KOYO, we are currently integrating NILA-3 here. Environmental tests—such as vibration and thermal-vacuum testing—are conducted at the IN-SPACe facility in Ahmedabad.
- Arun Raj: Beyond Low Earth Orbit (LEO) missions, HEX20 plans to expand into deep-space missions and larger satellite platforms. Collaborative missions with international partners, including the UAE Space Agency, are also in the pipeline.
