The Indian Space Research Organisation (ISRO) successfully launched its third and final developmental flight of the Small Satellite Launch Vehicle (SSLV-D3) on August 16, 2024. The launch, conducted from the Satish Dhawan Space Centre in Sriharikota, India, placed two satellites, EOS-08 and SR-0 Demosat, into orbit, marking the completion of the SSLV's development phase. This achievement enables the rocket's operational use by Indian industry and NewSpace India Limited (NSIL).
The primary payload, EOS-08, is an Earth observation satellite developed by ISRO's U R Rao Satellite Centre. The satellite was placed into a 475-kilometer low Earth orbit about 13 minutes after liftoff. EOS-08 is equipped with three advanced payloads: the Electro Optical Infrared Payload (EOIR), the Global Navigation Satellite System-Reflectometry payload (GNSS-R), and a SiC UV Dosimeter. These instruments will support a variety of Earth and atmospheric monitoring tasks, including disaster management and environmental surveillance. EOS-08 also features several new technologies, including an integrated avionics system and flexible solar panels, which will be demonstrated during its mission.

The secondary payload, SR-0 Demosat, developed by Space Kidz India, is a 0.2kg CubeSat designed for educational and amateur radio purposes. Deployed into the same orbit as EOS-08, SR-0 Demosat is equipped with an Inertial Measurement Unit (IMU) and a LoRa digipeater. The satellite's mission includes raising awareness about amateur radio and nano satellites among students, transmitting health telemetry, and serving as a Digital Packet Store and Forward System for radio amateurs worldwide. Additionally, SR-0 Demosat will act as a demonstration unit to qualify a new CubeSat deployer, reflecting Space Kidz India's innovative approach to space technology.
Space Kidz India, which developed SR-0 Demosat, has a history of launching educational satellites. The SR-0 Demosat continues this tradition, serving both educational and amateur radio communities. Operating on a 437.400 MHz downlink, the satellite supports various digital communication modes, including 9k6 FSK AX25, 4FSK SSDV, and 38k4 LoRa. This allows radio amateurs globally to engage with the satellite and collect valuable data. SR-0 Demosat's telemetry dashboard can be found on the SatNOGS website: https://db.satnogs.org/satellite/WZIT-9333-7102-4860-3049.

ISRO Chairman S. Somanath highlighted the precise placement of the satellites, noting that the successful deployment of both EOS-08 and SR-0 Demosat underscores the SSLV's readiness for operational missions. The SSLV, known for its low cost, quick turnaround, and flexibility, is suited for launching mini, micro, and nano satellites, which are increasingly in demand for commercial and educational purposes.
The SSLV-D3 launch represents a key step in India's space program. With the successful deployment of EOS-08 and SR-0 Demosat, ISRO has demonstrated its capability to deliver a range of payloads into orbit, meeting the growing needs of the global small satellite market. This mission also highlights the potential of space technology to inspire the next generation of engineers and scientists while advancing the capabilities of the amateur radio community.
