Indian space propulsion startup Bellatrix Aerospace has announced a successful early milestone for its newly launched satellite, Harbinger, confirming that the spacecraft has established communication and begun transmitting data from orbit.
In a statement shared shortly after launch, the company said, we have signal! revealing that Harbinger successfully “spoke back” to ground stations during its very first orbital pass.
The satellite, launched aboard a Falcon 9 rocket as part of SpaceX’s Transporter-16 rideshare mission, is currently operating at an altitude of around 510 km above Earth.
Engineers confirmed that the spacecraft locked onto signals and transmitted clean data at a ground station elevation of 14 degrees. Early performance metrics have also met expectations, with Carrier-to-Noise Ratio (CNR) readings of approximately 30 dB during orbit 5 and 45 dB during orbit 6, indicating strong and stable communication links.
Harbinger is a technology demonstration satellite designed to validate key in-orbit systems and propulsion technologies developed by Bellatrix.
Such missions are critical because space conditions cannot be fully replicated on Earth, making real-time orbital data essential for testing performance, reliability, and system behaviour.
The company emphasised that every subsystem aboard Harbinger, from design and manufacturing to integration and testing, was developed entirely in-house.
This marks a significant step for India’s private space sector, showcasing growing capabilities in end-to-end satellite and propulsion system development.
The mission has now entered the LEOP (Launch and Early Orbit Phase), a crucial stage during which engineers closely monitor the spacecraft’s health, stabilise operations, and begin initial system checks.
Industry experts note that successful early communication is one of the most critical milestones for any satellite mission. With Harbinger already transmitting data as planned, Bellatrix has demonstrated a strong start, paving the way for further testing of its advanced propulsion technologies in space.
The development shows India’s expanding footprint in the global commercial space ecosystem, as private players continue to achieve increasingly complex milestones in orbit.
