THE PROTOCOL FOR EVERYTHING
SoRC Link is a family of communication systems designed to provide complex connectivity within devices developed by the SoRC team. It covers a wide range of functions, from reliable real-time telemetry transmission and on-device data logging to internal communication between individual rocket subsystems.
For wireless transmission, LoRa technology is used in combination with frequency hopping spread spectrum (FHSS), which significantly increases the system’s resistance to interference and improves communication reliability.
The SoRC Link protocol itself is designed to be transmission-medium-independent and can operate over various communication interfaces, such as radio links, USB, Bluetooth, Wi-Fi, or, for example, the CAN bus.
APPLICATIONS
Development of SoRC Link began during the ELA rocket project with the goal of creating a more reliable solution for real-time telemetry. Originally, it was a simple data serialization protocol, but it has gradually been expanded to include additional features such as bidirectional communication with command support, packet delivery acknowledgment, and ensuring data integrity and confidentiality through signing and encryption.
SoRC Link is currently used in the ELA, Dart, ELA-CS, Doge V2, and CALA rockets, as well as in the CanSat Junior educational kits and other internal team equipment, such as the engine test stand.
Along with the protocol, a modular dashboard was developed that allows for easy handling of telemetry data from various sources, both in real time and during post-flight analysis.
