Hyderabad-based Dhruva Space and Bellatrix Aerospace, two Indian space startups, have achieved significant milestones in their recent experiments conducted on the Indian Space Research Organisation’s (ISRO) PSLV Orbital Experimental Module (POEM). Dhruva Space successfully tested its ‘Launching Expeditions for Aspiring Payloads – Technology Demonstrator’ (LEAP-TD) on ISRO’s platform, validating the P-30 platform and its integral subsystems in orbit. The experiments, conducted on the spent PS4 stage, included subsystems such as the On-Board Computer, Ultra High Frequency (UHF) TT&C Module, UHF Beacon, Attitude Control System, and Power Distribution Board. Bellatrix Aerospace, supported by the Defence Research and Development Organization (DRDO), successfully tested its high-performance green propulsion system, aiming to reduce satellite costs and enhance India’s space capabilities.
Dhruva Space’s LEAP-TD qualification is a significant achievement, setting the stage for hosted payload solutions. This approach allows entities beyond primary satellite operators to own a portion of the spacecraft, such as sensors, instruments, or transponders. The successful validation of key subsystems in orbit paves the way for the startup’s inaugural LEAP satellite mission (LEAP-1), scheduled for launch in the near future. Sanjay Nekkanti, CEO of Dhruva Space, emphasized the advantages of their hosted payload offering, including reduced timelines, rapid access to space, cost savings, risk mitigation, and various levels of payload command and control through their Telemetry, Tracking, and Command (TT&C) ground facilities.
ISRO’s POEM platform serves as a host for in-orbit experiments conducted by space startups, university students, and research institutes. This initiative optimizes the spent PSLV rocket stage, providing standard interfaces and packages for the design, development, and validation of experimental payloads. The successful experiments showcase the collaborative efforts between ISRO and private space enterprises, contributing to the growth of India’s space sector.
Bellatrix Aerospace’s achievement in testing a high-performance green propulsion system aligns with eco-friendly technology development supported by DRDO’s Technology Development Fund. This breakthrough is expected to lower satellite costs and enhance India’s space capabilities. The DRDO’s role in promoting such advancements reflects a commitment to fostering innovative solutions in the country’s space industry.
India’s space exploration efforts received additional recognition with the launch of XPoSAT on January 1, 2024, using ISRO’s PSLV-C58 rocket. Developed by Bengaluru’s Raman Research Institute, XPoSAT exemplifies India’s strides in space technology and exploration. Overall, these recent achievements underscore the collaborative and innovative spirit within India’s space community, contributing to advancements in space technology and capabilities.
