On 26 November, 2022, at 11:56 am, onboard ISRO PSLV-C54, Dhruva Space launched the Thybolt Mission to validate its P-DoT Satellite Platform and to enable many more amateur radio enthusiasts to be able to operate, test and learn in the journey of the company's first satellite mission. Dhruva Space anticipates this will encourage individuals, institutions and corporations to embrace the knowledge that amateur radio can contribute to their overall development.
The Thybolt Mission uses Dhruva Space's P-DoT Satellite Platform for conducting a sequence of technology demonstrations, as well as to enable advancements in research, constellation development and application agnostics use by customers.
To drive the success of this mission, Dhruva Space leverages technologies developed indigenously by the company across the Space, Launch and Ground Segments.
The Thybolt-1 and Thybolt-2 satellites are made on the Dhruva Space-developed P-DoT system. This is a 0.5U Spacecraft bus that includes a communication payload to enable rapid technology demonstration and constellation development for multiple users. It also demonstrates Store-and-Forward functionality for authorised users in the amateur frequency band.
This compact, scalable platform leverages a powerful processor and Space-grade components that enables high agility as well as reliable and robust operations.
The payload used on the satellite is a novel Store-and-Forward payload receiving messages from sensor nodes or remote Ground Stations; it also stores the aforementioned messages on-boardflash memory for downlinking them at a network connected ground station.
Amateur radio is a popular technical hobby and volunteer public service that uses designated radio frequencies for non-commercial exchange of messages, wireless experimentation, self-training, and emergency communications.
Amateur Radio – also known as HAM (the combined initials of scientists Hertz, Armstrong, and Marconi) Radio – is the only hobby governed by an international treaty. As a radio amateur, one is able to transmit radio signals on a number of frequency bands allocated specifically to the radio amateurs. One such use-case is communication through amateur space satellites or with the International Space Station (which carries an amateur radio station).
