About
The ODALISS TTC is an embedded CubeSat radio communication module, based on a fully configurable integrated half-duplex VHF/UHF transceiver and designed to simplify space-to-ground communications. It functions as an advanced radio transceiver capable of communicating within the VHF and UHF bands, with full remote reconfiguration capability via command from the On-Board Computer or the ground station. It is powered by a Cortex®M4 CPU, offering a wide set of commands for configuration flexibility. Key features include high reception sensitivity and transmission power, the possibility for redundant configuration to increase reliability, and a nominal mode using a non-proprietary protocol based on packet radio like AX.25. It also supports a beacon mode with periodic beacons using 2FSK Radioteletype (RTTY). The unit is designed for integration into CubeSats and operates within a wide temperature range.
